PVC Pelletizing Line

Case study of 80/156 UPVC pelletizing line

Pelletizing extruder for customized solutions

JINZE PVC pelletizing line adopts counter-rotating twin-screw extruders with output up to

800kg/h. The screw design can be customized according to your PVC formulations. You can

get wide output range by choosing from 51/105 to 92/188 conical twin-screw extruders. A broad

variety of PVC formulations can be processed by customized screw design. We also help to offer

suitable downstream equipments such as cutting die head, cooling devices and storage silos.  

Here is a case study of 80/156 UPVC compounding extrusion pelletizing line.
