Rigid PVC plastic pellets making machines

This PVC pelleting production line is composed by a conical twin-screw extruder and the correspondingly pelletizing downstream equipment, it is suitable for the pelletizing of PVCraw materials with wood powder or other additives. The pelletizing downstream equipment is the die face cutter, air transferring unit, vibration separating and cooling unit. This pelletizing downstream equipment has the features of high automation and high production efficiency. The screw and barrel, made of 38CrMoAlA , are made through smithing, tempering, double aging, nitriding treatment. Differences from others: screw edge is tempered after rough finish with good harden ability, and double aging reduce efficiently stress. Meanwhile, through accurate processing, phases of the screw edges have small error. The barrel and screw have high universal property. The structure of screw is different to different materials. And except the PVC powder recycling pelleizing line,we also have the pla…
