Single screw extruder

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.

Two-stage single screw extruder

The application of two-stage granulation system in the work of recycling: It is composed of two sets of single screw extruders to recycle heavy dirty raw materials or greater output.

Features of Two-Stage Re-Pelletizing System

1. Segmented filtering principle, fore filtering in the first extruder, and fine filtering in the second extruder, to reduce the frequency of filtering sieves changing.

2. Thanks to separated filtering system in two-stage extruder, system can realize steady extrusion job.

Has one more volatilization between first and second extruder.

Second stage’s extruder can present low temperature extrusion, which can guarantee the final production’s quality.

Plastic performance keeping

Thanks to precise temperature controlling and optimized plasticization design, ASE-Pro system ensure the reliable quality output of plastic granules.

Process

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.

Granulation Methods

According to the quantity and type of materials, the production line can be equipped with three kinds of granulation methods: water circumferential cutting, water-cooled stretching, automatic stretching or underwater granulation.
