Parallel co-rotating twin screw extruders have excellent mixing performance, good self cleaning performance and flexible modular configuration characteristics which make them suitable for processing different types of material systems, and are extensively used in fields of polymer processing, foodstuff processing and chemical products, especially for various high molecular materials. In most cases, parallel co-rotating twin screw extruders are used as mixing equipments. ln processing high molecular materials, the modification process and master batch preparation of polyolefin materials and engineering plastics require sufficient and intensive mixing, which differs depending on material systems, Excellent equipment performance, reasonable mixing process, advanced combination technique and rich processing experience are the key factors determining the success and efficiency of mixing.

This parallel double screw masterbatch granulate production line is applicable for most kinds of thermoplastic products with or without filling. As a water ring formed outside the die set plate , the die set plate does not contract cooling water, which ensures homogeneous die set plate temperature. Even at very low output, the discharge from the die set can still remain even and normal. the die set surface hot pelletizing system not only ensure saturated and good looking appearance of the material grains, it also makes the equipment structure compact and reduces equipment space as the material grains enter the cooling water ring immediately after pelletizing.
1. Plastic compounding, reinforcing, color masterbatch
2. Capacity: 10-1500kg/h
3. High torque/speed
