Rigid PVC Compounding Double Screw Extruder Machine Large Capacity

Configuration & Features

Up-stage is the twin screw extruder, compounding and extruding the material inside, then free falling into down-stage larger size single screw extruder for compression, low speed, cooling down extruding pelletizing, the two-stage installed to vertical “T” type.

Twin screw is for conveying, high efficiency compounding and shearing dispersing, no counter pressure because of no die head, which avoid temperature peak and ensure high output. Single screw is for cooling and high pressure, low speed extruding and pelletizing.

Excellent compounding effectiveness and high output, because of two stage design. 

Application:

Heat sensitivity polymers material processing, such as PVC cable compounds, transparent material, PE cross linking compound, PE shielded cable and foam material for shoes etc.
