PE PP PVC film plastic recycling machine double stage extruder
Two Stage Extruder
ZL series, that’s two stage compounding extruder consisted of two parts. Mainly there are three types of two stage extruder combination:
1.Single screw main extruder machine-single screw submachine
2.Single screw main pelletizing machine-twin screw submachine
3.Twin screw main pelletizing machine-single screw submachine
The first two types are widely used for recycled plastic granulating.
And the third type for heat-sensitive material like PVC, POM, XLPE etc.
The twin screw extruder (SJSL-) at the first stage is to realize good shearing and compounding for material, and then the extrusion and pelletizing by YD single screw extruder (second stage). The new, scientific and advanced design and structure can avoid material decomposition caused by material overheating
Application of Twin-Single Screw Extruder
Carbon black master batch
PVC cable, PVC transparent bottle and blood transfusion tube materials
PE silicon hydride crosslink cable material, peroxide crosslink cable material
Wood- plastic blending material
Heat-sensitive polymeride.
