PE/PP/PS/ABS/PA Grinding Rigid Plastic Pelletizing Line / Extrusion Mahcine

PE/PP/PS/ABS/PA grinding rigid plastic pelletizing line   Our system has been specially designed for recycling medium and large quantities of heavy regrind materials (> 300 g/l) such as PE, PP, PS, ABS, PA and PC. From a feeding hopper, the material is transported directly into the extruder by a screw conveyor without being precut or compressed. The rate of material feeding is controlled automatically by the load on the extruder motor. The system is designed so that overloading and underloading are avoided. Solid foreign substances are filtered by a continuous melt filter available with or without backflushing system. Depending on the type and quantity of the material the line can be equipped with a water ring, strand or underwater pelletising system. The particular advantage of our system is that no heating or other treatment of the material is necessary before extrusion. A clear and easy-to-use touch screen ensures a comfortable starting and stopping process and operation of the line. Our system comprises five machine sizes which together cover an output range of 100 – 1800 kg/h. Each machine can be equipped with degassing, high vacuum, backflushing filter and pelletizing systems (strand, water-ring or udner-water). Process description 1. screw conveyor;  2.
