To realize automatic feeding of plastic flakes, screw loader and screw feeder are equipped with single screw extruder.
As standard design, plastic flakes conveyed into the screw feeder by the screw loader, we can also install magnetic frame as optional in screw loader storage silo in case material with metal inside;
Feeder motor is controlled by ABB/Schneider inverter; level sensor which installed in the hopper of screw feeder help realize automatic feeding.
A specialized conical twin screw extruder applied to gently melt the crushed plastic scraps. Capacity range from 400-2000kg/h.
Extrusion part consists of high torque gear-box, motor, screw&barrel, vacuum degassing system.
Screw&barrel adopts bi-metal material, which enable much longer life time.
Ceramic heater as standard heater installed on the barrel to heat and melt plastic scraps, air blower to cool the barrel. Optional infrared heaters, which is easy assembly and disassembly, faster heating and energy saving. More effective heat conduction. Longer service life. Maintenance-free, Lower energy, higher output capacity.
Soft plasticization concept runs through the screw design, which provides a strong guarantee for the extrusion of PVC.
Reliable two-stage screw core external circulation temperature control system ensures that different formulations can produce high quality PVC products;
It has high efficiency and low noise air cooling system as well as reliable and effective vacuum exhaust system, high precision, wide speed regulation, forced quantitative feeding system, high performance gear box for reducing torque distribution, perfect precise temperature automatic control system, precise and stable speed regulation system.
Conical twin-screw extruder has the characteristics of homogeneous plasticization, high yield, stable quality, wide range of application, long service life, direct molding of PVC powder, etc. With the corresponding moulds and auxiliary machines, all kinds of thermoplastics, especially hard polyvinyl chloride powder, can be directly extruded into plastic products such as pipes, plates, sheets, rods, membranes and profiles. The modification of various plastics and granulation of powder can also be completed.
The conical twin-screw extruder has stable performance, can make melt well plasticized and extruded at lower temperature. The barrel is equipped with cast aluminium heater, which has high thermal efficiency, fast and uniform temperature rise. It is also equipped with cooling fan.
The specially designed transmission part adopts a new type of variable frequency motor or direct drive current motor, which runs smoothly, transmits large torque and has high efficiency. Through imported frequency converter or DC speed regulator, stepless and stable speed regulation can be achieved with high accuracy and energy saving. Intelligent double display digital temperature controller is adopted, which has high control precision and small temperature fluctuation. It has functions of overload protection and fault alarm, constant temperature of oil circulation in screw core, oil cooling in barrel, and equipped with vacuum exhaust pipe device and quantitative feeding device.
|Machinery size||Speed(r/min)||Motor power(kw)||Capacity (kg/h)||Total installed power(kw)|
* 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.
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.
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.
* Self-adjusting pelletiziin head for the best granulate quolity and long uptime thanks to consistently correct blades oressure.
* RPM of rotatory blades is automatic based on melt extruding pressure.
* Easy and fast pelletizer blades changeover, without adjustment work saves time.
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.
* 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.
Final output: plastic particles,the plastic pellets can be re-used for producing high quality plastic products once again.
* 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.
