          • “Beyond the Limits“
            SIEBTECHNIK has combined for solids separation from liquids and also for dewatering of solids the particular advantages of sedimentation and filtration into combination centrifuges.
            By employing our combination machines the separating efficiency is increased, compared with filtering centrifuges. In addition, also the efficiency of solids dewatering is increased and, therefore, the energy costs of the drying process are reduced. In case of an existing system it is possible to increase production capacity by exchanging a conventional machine against a combination machine.

            All SIEBTECHNIK combination centrifuges are adapted individually to the production environment and plant requirements.
            In the combination machines the solids are separated by sedimentation in a solid-wall section. After that it is possible to wash the product in the screening section and to dewater it up to the severable dewatering limit. The selection of the type of machine is governed by machine parameters, g-number, holding time and cake height.
            These combination machines have successfully operated in numerous industries and various applications. In the polymer industry this includes materials like polyoxymethylen (POM) and also copolymers and biopolymers. Regarding organic compounds amino acids, carboxylic acid derivates and in the foodstuff industry mono sodium glutamate (MSG) are processed.
              • TURBOSCREEN screen bowl decanter centrifuge

              • Customized according to specific application
                On standard solid bowl screen centrifuges the screening section is connected to the small diameter of the solid bowl cone and the diameter of the screen is identical. This design has the disadvantage of a low volume in the dewatering section of the centrifuge. This leads to a high solids load and the lowest centrifugal force at the solid outlet.

                The SIEBTECHNIK TEMA TURBOSCREEN screen bowl decanter centrifuge, is in screen-diameter and -design adapted to the specific application.
                The solid materials are separated by means of sedimentation in the solid bowl and thickened. This is followed by our special designed and dimensioned screen. Bearings on both sides allow high centrifugal forces and long residence times.
                Centrate, filtrate and solids are discharged in separate outlets.

                Advantages
              • CONTHICK screen decanter

              • Efficient separation plus pre-thickening
                The SIEBTECHNIK CONTHICK screen decanter is a combination machine consisting of a solid bowl in the product feed zone and a screen bowl fitted downstream.
                Solid materials are separated by sedimentation in the solid bowl and thickened. The product can then be washed and dewatered up to the mechanically separable dewatering limit. A further special feature of the CONTHICK is its overhung mounting. This design enables easy cleaning and fast access to the parts in contact with the product. As a result, maintenance costs and maintenance times are considerably reduced.
                The second stream of liquid is drained off through a separate drainhole.

                Advantages
                • Continuous operation
                • High yield/minimum loss of solid matter

                • CENTRIFLEX

                • The SIEBTECHNIK CENTRIFLEX centrifuge is a laboratory centrifuge designed for many different uses.

                  The CENTRIFLEX can be used to test the separability of suspensions in the centrifugal field. The choice of a type of centrifuge and the dimensional scaling of the centrifuge are possible on the basis of such laboratory tests. With our laboratory centrifuge filtering and sedimenting centrifuges as well as continuous centrifuges or centrifuges with batchwise operating mode can be simulated by appropriate tests. For this suitable beaker inserts are used in the centrifuge.
                  The CENTRIFLEX can also be used for many kinds of preparatory work.
                  When fitted with the appropriate accessories, they can be used for filtration, washing, clarification, for the continuous separation of two liquids and for the preparation of emulsions.
                  • Multifunctional laboratory centrifuge
                  • High g force (6000 g)
                • CENTRILAB

                • The CENTRILAB was developed on the basis of the CENTRIFLEX laboratory centrifuge and is used solely for testing the separability of suspensions in the centrifugal field. The choice of a type of centrifuge and the dimensional scaling of the centrifuge are possible on the basis of such laboratory tests. Practically every type of centrifugal separating apparatus can be tested and/or simulated very easily with the CENTRILAB, using a small quantity of material.

                  Unlike the CENTRIFLEX the CENTRILAB stands out for its considerably shorter starting and stopping times. It is possible to accelerate the product to be tested to maximum g force in under a second. In this way continuous centrifuges, which as a rule are operated with short material dwell times, can be very precisely copied in the test or in simulation.
                  • Portable test centrifuge
                  • Extremely short start/stop times
              • Sample taking and Sample preparation systems

                  • Sampling Equipment for Conveyor Systems

                      • Slotted-vessel samplers

                      • The slotted-vessel sampler is implemented for sampling materials at the belt head or in the downpipe. This sampling principle is based on a slotted-vessel with defined intake slot vertical to the dropping material stream that records the material stream’s entire thickness at a constant speed.

                        Advantages
                        • Simple and low-maintenance design
                        • High tolerance of unwanted materials in the product stream
                        • Application-specific drives for the slotted-vessel carriage using steel chains, rubber-block chains or toothed belts

                      • Hammer sampler

                      • Operating Behavior & Mechanical Characteristics
                        The hammer sampler is implemented for sampling materials from belt conveyors. The hammer sampler guides this sampling frame, which is closed on one side, in a circular movement through the material stream as it moves along the belt. In doing so it automatically removes from the belt a representative cross-sectional sample corresponding to that of the sampling frame.

                        Advantages
                        • A simple, low-maintenance and very operationally reliable construction
                        • Reliable removal of the fine contents from the belt bottom by the integrated brush and scraper
                        • No conversion from 3-piece to 5-piece roller stand necessary
                        • Hardly any expenditure for changes to existing belt installations for retrofitting
                        • Reliable monitoring of the position of the sampling hammer
                        • Reliable stopping of the sampling hammer by means of the disk brake fitted to the geared motor
                        • Lower primary sample quantities compared with slotted-vessel samplers
                        • Available for all belt widths, speeds and conveyor performances usual in the market

To be able to secure sufficient representativeness, the product flows to be sampled must be homogeneous in terms of the different grain sizes. Sampling is carried out by means of a sample collecting pipe protruding in the material flow.

                          This sample collecting pipe is provided with openings, into which the material can drop permanently. At the time of sampling, the screw-conveyor first of all empties the sample collecting pipe in the direction of the material flow. After a defined emptying time, the screw reverses and conveys the sample material dropped into the sample collecting pipe to a pipe socket outside the principal pipe.

                          Advantages
                          • Sampling from the material stream
                          • Low-wear and low-maintenance design
                        • Clinker sampler, Type KPN

                        • Operating Behavior & Mechanical Characteristics
                          Together with the piston sampler, the clinker sampler ranks amongst those samplers removing a selective sample from the material flow. For this purpose, a sampling spoon, which is filled with sample material over a defined period of time, is run into the product flow pneumatically. When the sampling spoon is drawn back, it is removed inside the sampler housing by a piston and the material sample pre-classified over a rigid sieve grid. The fine material thus obtained can be taken over for further analysis at a pipe socket. The coarse parts are taken over at a further pipe socket and fed to the principal material flow again.

                          Advantages
                          • Sampling from material flow
                          • Low-wear and low-maintenance design+
                        • Piston sampler, Type KoPN

                        • Operating Behavior & Mechanical Characteristics
                          The piston sampler ranks amongst those samplers which remove a selective sample from the material flow. To be able to secure sufficient representativeness, the product flows to be sampled must be homogeneous in terms of the various grain sizes. Sampling is carried out by means of a sample collecting pipe protruding in the material flow. This sample collecting pipe is provided with an opening, into which the material can drop permanently. At the time of sampling, a pneumatically actuated piston is pressed from the waiting position in the direction of the material flow by the sample collecting pipe. The sample collecting pipe is emptied over the material flow to then, on the return, take along the sample material just dropped in. The sample material can be taken over at a pipe socket outside the main pipe.

                          Advantages
                          • Sampling from the material stream
                          • Low-wear and low-maintenance design
                        • Downpipe slot vessel sampler, Type FLPN

                        • Operational behaviour and mechanical characteristics
                          Representative sampling is carried out by a slotted vessel that is guided by a pneumatic linear drive via a rod at constant speed through the complete chute cross-section. The multiple sealing of the rod bushing and the enclosure of the drive mean that the drive is not directly exposed to the product and thus remains practically free of wear. The passage speed of the spoon can be adapted to individual requirements by adjustable valves on the drive.
                          After the passage of the spoon, the sampling spoon is turned through the product flow via the sample discharge chute and thus emptied. The rotary movement is initiated mechanically by means of adjustable stops and therefore does not require any further drive.

                          Advantages
                          • Representative sampling from product flow
                          • Low-wear and low-maintenance design
                        • Downpipe swivel sampler, Type FSPN

                        • Operating Behavior & Mechanical Characteristics
                          Representative sampling is carried out by a slotted vessel that is swivelled through the material flow in a circular movement at a constant speed. While the slotted vessel is rotated through the material flow, a sample is removed from the material flow and collected in the slotted vessel. This sample is subsequently emptied by the movable base over the sample discharge chute. After being completely emptied, the slotted vessel swivels back into the waiting position. With this sampler as well, the waiting position lies outside the principle material flow to protect the slotted vessel from wear.

                          Advantages
                          • Representative sampling from product flow
                          • Low-wear and low-maintenance design
                        • Downpipe/ slurry sampler, Type FPN/TPN

                        • Operating Behavior & Mechanical Characteristics
                          Representative sampling is carried out by a sample chute that is guided in a circular movement through the material flow at a constant speed. While the sample chute is rotated through the material flow, a partial material flow is continuously separated and led off. The thus obtained sample material is collected via a pipe socket and further processed. While the waiting position of the sample chute between two samplings is inside the material space, it is, however, outside the principle product flow, so that direct contact between the sample chute and material flow is prevented and wear on the sample chute reduced.

                          • Operating characteristics & mechanical features
                            This slotted-vessel sampler is used for taking samples of slurry at free pipe, chute or sump outlets. This sampling principle is based on a slotted vessel that has a specified inlet gap set perpendicular to the inflow of material and can cover the full thickness of the slurry flow at a constant speed.
                            The slotted-vessel sampler moves from one of its stand-by positions, through the suspension flow and stops in the opposite position. As the sampler moves through the product flow at a constant speed, a representative sample is taken. The sample taken is diverted away and taken up in a trough. The sampler’s stand-by position is outside the slurry flow.

                            Advantages
                            • Sampling from material flow

                            • Rotary pipe divider

                            • Operating Behavior & Mechanical Characteristics
                              With the rotary pipe divider, the uniformly added material stream is distributed into a funnel-shaped cone via a sloped rotating pipe.
                              The cone has recesses in the divider circle. The product passing through this recess is designated the “sample”, the material collected via the funnel the “rejects”.
                              The openings for the sample can be closed by means of a slide plate, resulting in a variably adjustable dividing ratio.
                              The rotary pipe divider can be implemented for easily pourable material not tending to plug. This divider can be cleaned through large inspection openings

                              Advantages
                              • Variably adjustable dividing ratio
                              • Low-wear and low-maintenance design
                              • Designed with increased accessibility, so minimum cleaning time
                            • Rotary divider

                            • Operating Behavior & Mechanical Characteristics
                              The rotary divider has a vertically appointed disk provided with openings which is rotated by a motor.
                              The sample material is uniformly fed to the divider via a dosage unit and guided onto the rotating disk. It passes through the opening in the disk as a “sample” or is deflected by the disk as a “reject”.
                              The dividing ratio (1:2 up to 1:130 depending on the type concerned) in this divider can no longer be varied after production due to the simple design.
                              The divider is used for dividing dosable, pourable and hardly caking materials.

                              Advantages
                              • Low-wear and low-maintenance design
                            • Turnstile divider

                            • Operating Behavior & Mechanical Characteristics
                              The turnstile divider is a divider that, with slight modifications, can be used for practically all products from cokes in lumps, plugged fine coal right up to super-fine-milled quick lime. The sampled material can be transferred to the divider’s charging area without prior dosing, since it is thoroughly mixed and dosed prior to the dividing stage proper by the inwardly-directed raking arm.
                              The material transferred to the middle of the divider plate via the first raking arm is now uniformly transported in a spiral movement outwardly over the edge of the plate by a second raking arm and drops onto a conically worked sheet housing, which is partly recessed. The product dropping onto this recess is designated the “sample”.

                              Advantages
                              • Very reliable operation even with wet and sticky products
                              • Low-wear and low-maintenance design
                              • Designed for increased accessibility, so minimum cleaning time
                              • Variably adjustable dividing ratio
                              • By arranging two dividers one behind the other dividing ratios of well over 1:1000 can be achieved.

                              • Sample collectors

                              • Should samples be collected only at protracted time intervals, we offer the possibility of keeping them in so-called sample collectors of the most varying sizes until they are collected.
                                The sample bottles are placed in a roundabout and are turned to the next empty bottle when filled.
                                In the extensive range, you will find machinery and devices for transporting the samples, such as space-saving and encapsulated special belts, for screen analysis, drum tests, and further laboratory instruments for preparing the obtained samples for analysis.

                                Advantages
                                • Large selection of sizes

                              • Operational behaviour and mechanical characteristics
                                The TR500 sample dryer is used for the chargewise drying of wet bulk materials. Drying of the wet bulk material is done by means of a heating plate that is made to shake by an unbalance motor. The arrangement of the unbalance motor causes the material to be continuously turned over throughout the drying process and so repeatedly presented to the hot plate. Heat is fed to the hot plate by means of thermal oil that is heated up by means of a temperature control unit with a heat range of between 50 °C and 180 °C.

                                The material to be dried is fed onto the middle of the shaking, heated dryer and spread over the heating plate. The dryer is emptied by changing the direction in which the unbalance motor is rotating, so changing the shaking movement and enabling the dried bulk material to be removed.
                              • Air slide sampler

                              • Operating Behavior & Mechanical Characteristics
                                在这些采样空气活塞取样器等级remove a selective sample from the material flow of an air slide conveyor system. To be able to secure sufficient representativeness, the product flows to be sampled must be homogeneous in terms of the conveyor width. Sampling is carried out by a sample collecting pipe protruding in the material flow that is provided with openings. Normally, these openings are turned in the direction of conveyance and close against a sealing gasket. At the time of sampling, the sample collecting pipe with its openings is turned against the direction of conveyance, so that sampling material can flow in. The sample material thus entered is discharged downwards through the air slide conveyor system by means of the sample collecting pipe.

                                Advantages
                                • Sampling from the material stream
                                • Low-wear and low-maintenance design
                            • Automation

                            • Continuously increasing demands on quality of raw materials and final products in industry ask for modern processing techniques, more accurate control and optimisation of production processes and, finally, monitoring of product quality.

                                • Automatic Moisture Analyser System (AMAS)

                                • This fully automatic system can determine the moisture content of bulk-material samples of up to 6 kg in weight. For this purpose, the AMAS can be integrated in an automatic sampling unit, thereby allowing the analysis to be carried out immediately after the sample has been taken from the material.
                                • Automatic screening and strength testing system (ASST)

                                • The automatic screening and strength testing machine is used for fully automatic grain size analysis and determination of the impact resistance of sinter, coke and other dry bulk materials.

                                    • Pneumatic tube system – fully automatic transportation of bulk material samples
                                      The fully automatic transportation of bulk material samples to the laboratory is undertaken by our pneumatic tube systems designed and produced individually for your physical circumstances.
                                      The sample material delivered from the samplingsystem is automatically filled into a carrier and subsequently transported to the required position by a tube system that may well be several hundred metres long. There, the carrier is automatically opened, and the sample discharged.

                                      Advantages
                                      • Fully automatic transport of your samples
                                      • Individually adapted to suit your space conditions
                                      • Can be combined with automatic sample processing systems
                                • Comminution Equipment

                                • For size reduction of differently hard products we can provide a selection of different comminution equipment: hammer mills, double-roller and single-roller mills, jaw crushers, cone crushers, continuously working vibrating disc mills and eccentric vibrating mills. From crushing to milling down to analysis fineness, we do have in our program the machine fitting your needs.

                                  When selecting the best suitable size reduction unit the product and the quality characteristic to be analysed are always the decisive factors.
                                    • Eccentric vibrating mills

                                    • The ESM has convincingly proven its performance in the most varied applications and feed materials in the field of mechano-chemical activation and micro-grinding,
                                      Only the single-tube eccentric vibrating mill of SIEBTECHNIK GmbH executes, through an exciter unit provided outside, inhomogeneous movements, comprising elliptical, circular and linear vibrations. The upshot is a high degree of loosening of the mill filling with very high impact load on the material to be ground, particularly with large amplitudes. The high specific energy input with a high degree of loosening of the mill filling is a decisive benefit of the single-tube principle, which, caused by the design, also makes a clear reduction in the mill mass and thus in the drive energy possible.

                                      Advantages
                                      • This modular design of the machine offers enormous advantages particularly with larger machines:
                                      • The mill can be split up into small units for transport and installation
                                      • The power train fitted completely on the outside of the mill body is freely accessible once the protective guards have been dismantled
                                      • All drive components and particularly the compact exciter units can be easily exchanged in case of maintenance, whereby downtimes can be considerably reduced compared to circular-oscillating mills
                                      • Furthermore, the grinding vessel modules considerably simplify the change of the grinding media and wear lining
                                      • The grinding vessel modules enable the grinding vessel lengths to be adapted to individual performance requirements or to changed performance requirements in the course of operation
                                    • Drum mills

                                    • The drum mills are used for fine and ultra-fine grinding of brittle materials. Discontinuous operated drum mills make, in addition to size reduction, homogenization of the material to be ground possible.
                                      Drum mills have a horizontal grinding drum rotating around a fixed center of rotation. Located in this cylindrical working space is a grinding-media filling, which is tumbled by the rotating grinding drum. The material fed is pulverized by the freely moving grinding-media primarily through pressure, impact and shearing action. Balls or Zylpebs are usually used. For special applications, steel rods can also be implemented in appropriately modified drum mills.

                                      Advantages
                                      • Low-wear and low-maintenance design
                                      • Can be used for thermically sensible or very hard product
                                      • Grinding finenesses stepply adjustable
                                      • End finesses of max. less than 2 mm
                                      • Optional separating device
                                    • Cone crusher

                                    • Cone crushers, slow-operation size reduction machines, are perfectly suited to produce cubic particle or to reduce heat-sensitive materials or very hard materials (such as corundum, ferrous Silicium, ore iron ores).

                                      Operating Behavior & Mechanical Characteristics
                                      The feed material is crushed between the slowly rotating cone and the static outer grinding ring. By rotating the feed funnel, the size of the slot between cone and ring can be adjusted as required, therefore achieving the fineness of material requested. Maximum final particle sizes of < 2 mm can be achieved due to the tooth system of the fine cone.

                                      Advantages
                                      • Low-wear and low-maintenance design
                                      • Can be used for thermically sensible or very hard product

                                    • Single-roller mill
                                      With the single-roller mills, brittle, soft to medium-hard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5.

                                      The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being minimised, so that, compared to the double-roller mill, coarser material can be drawn in.

                                      Double-roller mill
                                      With the double-roller mill, all brittle materials, such as, for example, ores, clinker, limestone, gypsum, aluminium oxide, glass, … can be reduced in size up to a Mohs’ hardness of approx. 8.5 with a reduction ratio from 1:2 to 1:5.

                                                  The motion of the grinding balls inside the barrels does also entail an intensive homogenization of the material.
                                                  The grinding process can be either dry or wet. The size and kind of the grinding balls determines the final particle size. Normally, the grain size of the feed material should be smaller than 2 mm. The final particle size which can be achieved is smaller than 1 µm, depending on the material.
                                                  As the grinding barrels are exchangeable, their material (steel or ceramics) can be chosen so that contamination by abrasion can mostly be avoided. The exchange of the grinding barrels with help of clamping devices is very user-friendly.
                                                  The vibrating frame with the maintenance-free unbalance motor is supported on springs and covered by a housing with sound isolation. The counterweight at the bottom of the housing ensures a solid support and a smooth operation of the machine.
                                                  The machine is controlled by a foil protected keyboard which is situated in the opening cover of the machine and offers the function “On/Off” and the possibility to determine the duration of the grinding process.

                                                • Operating Behavior & Mechanical Characteristics
                                                  Grinding in the disc mill is done between two roughly toothed grinding discs. One grinding disc is stationary, the other is rotated by a geared motor, thus exerting a shearing action on the material to be broken up. The gap between the two grinding discs determines the fineness of the material ground up. By means of an adjuster wheel with an integrated scale to alter the position of the stationary grinding disc the gap width between the two grinding discs can be repeatably set. The ground-up material falls into a glass bottle placed underneath the grinding discs.

                                                • Operating Behavior & Mechanical Characteristics
                                                  The feed material is crushed between the slowly rotating cone and the static outer grinding ring. By rotating the feed funnel, the size of the slot between cone and ring can be adjusted as required, therefore achieving the fineness of material requested. Maximum final particle sizes of < 2 mm can be achieved due to the tooth system of the fine cone.

                                                    • Our solution for classic applications
                                                      A SIEBTECHNIK circular-motion screening machine is the classic solution for process requirements in screen classification. It is a freely vibrating screening machine that vibrates in a circle and is mounted on helical compression springs. Screen box and unbalance mass are optimally coordinated in their mass ratios. This enables a harmonious vibrating motion to be transmitted to the screened material at all points on the machine. Speed and vibration amplitude of the machine can be varied specifically to suit the product and so ensure a lastingly perfect screening result. The robust construction using and combining standard component parts ensures high flexibility and enables customer-focused solutions. Moreover, machines can be constructed with a low-maintenance running time and a long service life.

                                                      The SIEBTECHNIK excenter screening machine is ever ready for anything thanks to its fixed vibration amplitude. Excenter screening machines have been superbly proving their worth as pre-separators with stepped heavy perforated plates or a robust stepped grid under hard conditions for many years.
                                                      Pre-separators are preferably used before the first crushing stage in stone quarries, ore mines and slag processing plants. The stepped screen area enables the screened material to be well relayered.
                                                      In the case of feed material with long, thin and pointed bits that tend to jam we recommend for optimum results a stepped grid with slots that get larger in the direction of transport. Also 2-deck solutions are feasible and enhance the classifying process.
                                                      We build our excenter screening machines for you with nominal screen widths of up to 2100 mm and screen lengths of up to 4000 mm.

                                                      Advantages
                                                      • High feed
                                                      • Robust slotted grids for pre-screening of stone of all kinds
                                                      • Efficiently relieves loads on downstream comminuting units
                                                      • Reliable wear protection
                                                    • Hot Mineral Screening Machine

                                                    • Hot mineral screening machine by SIEBTECHNIK TEMA with improved dust guard
                                                      标准asphalt-bound制造基地and surface layers stationary, semi-mobile or mobile asphalt mixing systems are employed. These consist essentially of a dry drum, bucket conveyor, screening machine, aggregate silos, weighing and mixing equipment and a shipment loading system.

                                                      The aggregates, which make up about 80 to 90 per cent by weight of the asphalt formulation, are heated to the required temperatures in the burner-heated dry drum. The quality of the asphalt layer depends on, amongst other things, the quality of the binding materials and the correct grain composition of the largest component by volume, the grainy aggregates. For this reason the screening machine is of especial importance

                                                      The SIEBTECHNIK TEMA type HN screening machine has the advantage that the drive mounting is positioned outside the fixed dust guard enclosure and so outside the heating zone. Hot chippings at temperatures of up to 450 °C have been reliably screened with this system in numerous applications.

                                                      Here the right choice of screen cloth and the kind of screen cloth tensioning is also important.

                                                      The excellent accessibility of the machines in combination with dust guard covers that enable temperatures to be rapidly lowered are an important requirement for short down-times in cases of maintenance or repair. The dust guard available since 2001 in the new, split version with fully extendable chute carrier brings a further improvement on earlier systems here.

Also with a relatively high near-mesh-sized grain content and critical water content we recommend our multi-deck machines with up to 5 screen decks one above the other. The mostly monogranular screening, made possible by an especially steep screen deck tilt in the lower section, enables high specific screening performances and good classification accuracy, even with small screen holes.

The large number of nearly vertical throws, the lighter load on the decks and the large screen area enable finished products in analysis screen quality.

                                                      We build channel conveyors with top- or bottom-mounted drive units for extreme size requirements. The transport of coarse-grained or very hot feed material or the even loading of a downstream screening machine with feed material is nothing to these vibrating machines.

                                                    • Expert in density separation
                                                      The SIEBTECHNIK pulsator jig is specially designed for the separation of light material from heavy material in grain size > 1 mm. This includes the separation of harmful materials from e.g. sand and gravel, slags, building rubble and contaminated soils as well as the separation of different ores.

                                                    • Our non-vibrating systems for the processing of suspensions.
                                                      SIEBTECHNIK curved-screen systems (type ZB or ZBB) are dynamic dewatering and classifying screens, even though they contain no mechanically moved parts. The system consists of a stationary housing that is fitted with a concave-curved screen cloth. The systems have been specially developed for the separation of solid materials from process or waste water and achieve optimum results at a low cost.

                                                      Advantages
                                                      • High throughput, which even in continuous operation remains unchanged because of the self-cleaning action or a cleaning device.
                                                      • High separating accuracy because of the non-dependence on the specific weight of the solids and the solution – unlike with flow classification.
                                                      • Low installation costs thanks to small space requirement because of the compact construction combined with a high specific performance.
                                                      • Low running costs thanks to low-maintenance operation through the non-use of mechanically moved parts.

                                                    • Adaptable fine-screening specialist
                                                      The SIEBTECHNIK CONFLUX type C tumbler screening machine offers outstanding adaptation options to meet the most stringent requirements in fine-screening and ultrafine-screening technology. It is suitable for classifying, dedusting, dewatering and control-screening.
                                                      The CONFLUX is a round screening machine with a variable screen set-up and a co-vibrating drive motor with changeable vibration exciter.
                                                      The vibration patterns can be optimally set to suit the screened material and for the required screening result by simply shifting the unbalance weights of the lower vibration cell.
                                                      Depending on the number of grain separations required, up to three drums can be mounted on top of one another and so a maximum of 3 separating cuts and 4 size fractions achieved. Oversize and undersize grains are removed at the side, at separate discharge outlets.
