ACT Conical twin screw extruder recycling machine

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.
