    Composition and operation process

    Overview


    View Detail


    Feeding

    Feeding

    As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. 

    Shredding/Enforcing feeding

    Shredding/Enforcing feeding

    In collaboration with European shredders supplier, the specialized shredding rotors set to combine with single screw extruders, to pre-reduce, crush and enforcing feed various plasticsscraps; the plastic scraps can be in form of film, bottles, raffia, woven bag/non-woven, fabrics, purges, lumps; it is a universal system for all kinds of plastic scrap, in any kind of condition.

    Single Screw Extruder

    Barrel

    Because of the super L/D ratio, the single stage extruder in the production line can be used as a double- stage extruder. After the middle double-piston type screen filter, another filter can be added at the end. The double filter standard can improve the quality and performance of the final product particles.

    Single Screw Extruder

    Our unique design single screw extruder gently plasticizes and homogenizes the materials. Our bi-metal extruder has great anti-corrosion resistant, wear resistant and long life time.

    Intelligent Control 

     Remote Monitoring and Information Transmission

    System program remote monitoring and transmission system,bluetooth both are available for ACS plastic pelletizing line realizing functions of remote monitoring and information transmission.

     Intelligent Control

    Intelligence Start: One button only Following set logistical sequence and materials processing requirement, interlocked system modules can start by "one button only” Intelligence Stop: One button only Each related modular part in ACS system available to shut down by only one button. Emergency Stop Emergency stop function is available in ACS plastic pelletizing system in case that uncertain risk occurred during machine running.

    Filtration System


     None-Stop Piston Type Filter
    • A regular single-plate/piston double-station screen changer or non-stop double plate/piston four-station can be installed on head of extruder to present significant filtration performance.
    •  Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas.
    •  Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
    • Very low operation cost.


     Plate Type Filter

    The Plate type filter is made in a continuous type with two filter plates. There is at least one filter working when the screen is changing.Ring-shaped heater for consistent and stable heating.



    Self Clean Filter

    This model combines our self-developed self-cleaning filter.The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly contaminated materials re-pelletizing. SCF filtration system can handle and remove up to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and rubbers etc.


    Pelletizing System

    Die Head

    This is the most appropriate process for the need for better melt filtration and higher production. In the first stage,two or more single screw extruders can be designed for the two-stage pelletizing production line, and then they can enter the second-stage extruder at the same time.

     

    Water Ring Pelletizing System
    • Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure.
    •  RPM of rotatory blades is automatic based on melt extruding pressure.
    • Easy and fast pelletizer blades changeover, without adjustment work saves time
    Strand Pelletizing

    The strip-shaped Melted plastic strands passes through the cooling water tank and is quickly cooled and solidified. During the cooling process, the strip is pulled out by the traction device, maintaining a certain speed and stability. Then, the strip enters the pelletizer and is cut into pellets of a certain length by the rotating cutter.

     

    Under-Water pelletizing system

    Highly automatic pelletizing system. It is suitable for materials with high MFI and high production capacity requirements. This system includes pelletizer, valve, conveying pipeline, dewatering vibrating screen, silo.

     

    Vibration Dry

    Vibration Dry
    • Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption. 
    •  Assemble sieves: The sieves are installed and fixed by screws instead of welding, so you can change the sieves easily in the future.
    Plastic Particles

    Final output: plastic particles,the plastic pellets can be re-used for producing high quality plastic products once again.

     

    Packing System

    Packing System
    • Final qualified granules store here,the drying shaker together with the horizontal centrifuge can get a good drying result, and less energy consumption.
    • Capacity online monitoring & Quantitative weighting system.
