  • PRODUCT OVERVIEW

      • 水下切粒EUP、过程水分R AND DRYING SYSTEM EWT

      • ECON is the leading provider of underwater pelletizing technology with thermally insulated die plates. The die plate is fixed on the heated carrier body. The thermal insulation ensures that the melt in the die holes will not "freeze". ECON pelletizers are not sensitive to fluctuations in output, thus making the pelletizing process extremely reliable and guaranteeing high operating efficiency.

        In addition, the compactly and clearly designed ECON water treatment and drying system is an effective solution for drying the pellets. The continuous filtration of process water ensures low maintenance requirements. Because the pellet dryer is easily accessible and free of dead spots, material or color changes can be done quickly. The complete pelletizing line can be easily adapted to different production conditions, thus increasing your flexibility.

        • easily accessible pellet dryer, free of dead spots for simple and safe cleaning

        Types

        Generally, ECON's underwater pelletizers are offered in combination with the water treatment and drying system (EWT).

      • VIBRATION DRYING SYSTEM EVS

      • Especially for materials with high filler content (e.g. with glass fibers or with mineral fillers), the vibration drying system is an excellent alternative to the standard centrifugal dryer. The gentle drying of the pellets ensures little wear and a low amount of fines. A residual humidity as low as 0.05 % can be reached.

        Function
        The vibration drying system consists of two or three sequentially arranged vibrating screens. The first stage serves for dewatering the pellets. In a dehydrator, the pellets are separated from the process water before they enter the screen. The process water is cleaned by an automatic band filter and recirculated to the process.

        In the second stage, the pellets undergo further drying. Electrical damping registers are installed under the vibrating screen to generate a warm stream of air through the screens.

        An additional stage can be installed to treat highly hydroscopic materials with even more stringent requirements for residual humidity.

        Types

        The ECON vibration drying system is suitable for throughputs up to 3,000 kg/hr.

      • Air Pelletizer ELG, Water & Air Pelletizers EWA

      • The ECON air pelletizer was especially developed for processing wood and natural fiber compounds (such as WPC). Because water is used to cool and convey the pellets, processing wood-plastic compounds in an underwater pelletizing system requires a substantial amout of drying. Common drying methods are often unable to attain satisfactory levels of residual humidity.

        The air pelletizer was designed to use air to cool and convey the pellets and thus eliminate any need to dry the pellets. At the same time, the system benefits from the thermal insulation, resulting in a uniform cut and easy conveying of the pellets from the "cool" cutting surface, without generating chains or agglomerates.

        Among natural fiber compounds, the ECON air pelletizer is also well suited for processing PVC, which has a low inner specific heat, therefore requiring only minimal cooling.

        The air pelletizer can also be combined with the ECON underwater pelletizing system, resulting in the water & air pelletizer EWA. Especially for laboratory applications this combination provides benefits in terms of flexibility and space requirements. With only a few modifications, one system can be used for both underwater and air pelletizing. Within just a few minutes the machine can be converted from air to underwater pelletizing and vice versa.
        • all advantages of the thermal insulation technology
        • highest flexibility
        • two different applications combined in one machine

        Function
        The air pelletizing system consits of a pelletizing unit, a conveyor fan with noise reduction cover, piping and a cyclone and an electrical control system.

        融化是针对造球头the die plate installed, and the emerging melt strands are pelletized.. The pellets are moved by an air stream that is produced by the conveyor fan. By the air stream the pellets are dried and are discharged through the cyclone.

      • Pellet Dryer S+L

      • ECON's pellet dryers, S+L, can be combined with the ECON water treatment and drying system, but they are also suitable for stand-alone operation. These dryers are often used in the recycling industry to dry bulk or mill material or flakes. These centrifugal dryers are characterized by their compact design and sturdy construction. Depending on the temperature, size and structure of the material to be dried, residual humidities between 0.1 and 0.5 % can be attained.
        • compact design and sturdy construction
        • high throughput
        • gearless drive for maintenance-free operation

        Function
        The granules/water mixture is supplied to the drying chamber through the inlet case, which is incorporated as a sieve in the bottom. The granules are collected in the drying chamber by a rotor equipped with blades and are spirally conveyed upward through the sieve basket. The water is collected by bouncing and rolling the granules frequently on the sieve basket. The dried product leaves the dryer in the airflow through the tangentially arranged nozzle on the dryer top cover. The water outflow takes place through an outlet in the bottom of the housing or in the housing side.

        Types
        The pellet dryers are available with different input systems and/or several optional components (such as sound insulation), depending on your requirements. In addition, special gas or explosion proof and wear-protected designs are available.

      • Screen Changer ESD

      • With discontinuous screen changers, the screens are changed when the machine is stopped. The piston carrying the screen is moved out and the screen pack is switched.

        For melts with very low viscosity (e.g. PET or PA), the ESD has been further developed to the "ECON thermo sealer" (ETS). This model offers air cooling at the end of the pistons and is therefore leak-free, even with low viscosity materials.
        • approx. 65 % effective screen area for higher throughput
        • flow-optimized design of the melt channels
        • extremely low pressure build up protects material and screens
        • no dead spots for faster material changes

        Function
        To change the screens the machine has to be stopped. The piston carrying the screen is moved out hydraulically and the screen can be exchanged.

        Types
        The discontinuous screen changers are appropriate for throughputs from only a few kg/hr up to 2,500 kg/hr.

      • CONTINUOUS SCREEN CHANGER ESK

      • The continuous double-piston screen changer allows screens to be switched out during operation.
        • all thermoplastic materials can be processed
        • optimal design of the melt flow way - short melt residence time
        • low pressure build up - to prevent thermal variations of the melt
        • no dead spots for fast changes of material and color
        • operational reliability and long durability

        Function
        Normally, the melt is spread over both pistons, each containing one screen pack. After a defined maximum pressure is met, one piston is moved out hydraulically and the screen pack can be changed. Meanwhile, the complete melt is directed over the second piston. After exchanging the screen pack, the piston is moved back and the production process continues. Afterwards the procedure is repeated with the other piston.

        Types
        The discontinuous screen changers are appropriate for throughputs from only a few kg/hr up to 2,500 kg/hr.

      • CONTINUOUS SCREEN CHANGER WITH BACKFLUSH SYSTEM ESK B

      • The continuous double-piston screen changers with backflush system provide major advantages with their fully automatic cleaning of the screens as soon as a defined maximum pressure is met.
        • all thermoplastic materials can be processed
        • optimal design of the melt flow way - short melt residence time
        • low pressure build up - to prevent thermal variations of the melt
        • no dead spots for fast changes of material or color
        • approx. 75 % effective screen area
        • operational reliability and long durability

        Function
        The piston in the backflush unit redirects the melt flow, so only one piston with screens is currently being used in the production process. The other screen pack is flushed backwards, so any contaminants with only minimal melt are removed from the screens through the backflush unit. Afterwards the process is repeated with the other screen pack.

        Types
        连续与反冲系统屏幕改变者em are available for throughputs up to 3,750 kg/hr.
