ASE Single screw extruder recycling machine

Lumps or thick flakes after crushed, conveyed into the single screw extruder by screw loader, then, compress, plasticize in the extruder and removed volatiles and moisture by vacuum system, after filtering through the filtration system, to pelletize into granules. Depending on the different screw diameters of single screw, the typical capacity can cover from 100kg/h to 1000kg/h,Loading motor power: 2.2 kw. Conveying pipe made with stainless steel material, pipe inner thickness is 2mm, pipe diameter is 102mm

By screw’s rotation, the plastic material goes forward, to finish the processing of compacting, melting, homogenization. Material of screw adopts qualified nitride steel(38CrMoAlA), process of CNC, with nitride treatment, has the ability of corrosion resistance and wear-resisting. With the specialized design of screw, even running with high speed, the material of polyolefin can be well melted under lower temperature and lower melting pressure.

It is part of screw pair, made of nitride steel, inner surface with nitriding treatment, to present higher surface hardness and better wear-resisting. The hot energy generated by heaters transmits through the barrel to the inside plastic materials, makes the plastic melting; with the temperature sensors and cooling fans which assembled on each heating zone.

Its function is to remove the low molecule and remain moisture from the melts which happened during the plastic raw material melting.

The vacuum degassing system consists of vacuum pump, vacuum room, filtering tank, pressure guage and pipelines. Vacuum pump is water ring type, forms the high negative pressure by the water sealing, suitable to waste gas and water enforcingly separate.

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. the requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.

Water ring pelletizing system set as the standard granulating method. self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. The production line can be equipped with three kinds of granulation methods: water circumferential cutting, water-cooled stretching, automatic stretching or underwater granulation.

Advanced dewatering vibration sieve combining with horizontal- type centrifugal dewatering present high-performance dried pellets and lower energy consumption.

Final output: Plastic granules
