Two Stage Recycling Extruder Machine for PVC Plastic Granules Pellets

Two Stage Recycling Extruder Machine for PVC Plastic Granules Pellets

The characteristics
1.The first stage is SHJ twin screw extruder with out die.Via the combination of barrel and screw, the extruder can exert  its sturdy capacity to make the thermo sensibility material like PVC melting, compounding,dispersing and decentralizing beneath the situation of no again pressure
two.The CZPT phase is SJ one screw extruder.Since of the lower rotating pace, it can full melting,compounding lengthways and forming srands steadily, avioding more than heating.

Two phase air cooling extruders

Mix the high velocity and extensive mixing of processing and the lower speed, reduced temperature, and reduced shear of solitary screw processing
Best for compounding of heat and shear-sensitive components.
PVC compounds for cable, shoe sole, clear container, and medical purposes EVA defend cable compounds
CZPT black master batches of PE, EVA, and so on.

Comprehensive information for SP75-one hundred eighty:

7) 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.
2.Single extruder SJ-180/85-90-22
1)180mm L/D = 28, rotary speed is 6~65rpm.
two)Main drive motor: AC 90Kw. ABB transducer,.
three)The material of barrels and shafts is nitride steel (38CrMoAlA).
4)Water-cooling inside the core of shafts.
five)Casting aluminum heaters, All heating power: ~36kw
6Enlarged screen changer  , material through 72 hours’ nitrogen treatment . The channel is short, with little melt left and easy to clean.
seven)Tailor-made flange:connect the single and twin screw extruder.
