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.
