PVC Recycling Compounding Granules Making Two Stage Extruder

PVC Recycling Compounding Granules Making Two Stage Extruder

The qualities
1.The first phase is TSE twin screw extruder without die.By means of the mix of barrel and screw, the extruder can exert  its robust capability to make the thermo sensibility materials like PVC melting, compounding,dispersing and decentralizing beneath the condition of no again stress
two.The CZPT phase is SJ solitary screw extruder.Simply because of the decrease rotating speed, it can full melting,compounding lengthways and forming srands steadily, avioding more than heating.

Two stage air cooling extruders

Blend the higher velocity and substantial mixing of processing and the lower speed, reduced temperature, and lower shear of single screw processing
Excellent for compounding of warmth and shear-delicate resources.
PVC compounds for cable, shoe sole, clear container, and health care apps EVA protect cable compounds
CZPT black learn batches of PE, EVA, and so forth.

seven) Reducing and distributing gearbox:
  The gearbox reduces the motor speed to the speed of the screw shafts and distributes it to the two output shafts. This gearbox output torque can reach     4.8T/A3
    The gearbox consists of:
l Involute gear teeth couplings between the output shafts and screw shafts
l Integrated thrust bearing assembly, radial bearings of the output axis are NSK products 
l Bottom part of casing designed as oil sum
eight) Soft water cools the barrels with condenser.
      Material of input and output pipes is stainless steel. 
      Solenoid valve: imported products. 
      Manual valve: stainless steel. 
      The water pump motor in the soft water system is 0.55kw. 
      The soft water is distilled water.
