Sp75-180 PVC Cable Grade Material Plastic Compounding Machine

Sp75-180 PVC Cable Grade Material Plastic Compounding Machine

The traits
1.The first phase is SHJ twin screw extruder without having die.By way of the mixture of barrel and screw, the extruder can exert  its sturdy capability to make the thermo sensibility material like PVC melting, compounding,dispersing and decentralizing under the problem of no again force
2.The CZPT phase is SJ solitary screw extruder.Simply because of the reduce rotating velocity, it can total melting,compounding lengthways and forming srands steadily, avioding more than heating.

Two stage air cooling extruders

Merge the substantial pace and in depth mixing of processing and the low velocity, low temperature, and lower shear of one screw processing
Best for compounding of heat and shear-sensitive resources.
PVC compounds for cable, shoe sole, transparent container, and medical apps EVA shield cable compounds
CZPT black learn batches of PE, EVA, and so forth.

In depth data for SP75-a hundred and 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
8) 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
one)180mm L/D = 28, rotary speed is 6~65rpm.
2)Main drive motor: AC 90Kw. ABB transducer,.
3)The material of barrels and shafts is nitride steel (38CrMoAlA).
4)Water-cooling inside the core of shafts.
5)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.
7)Tailor-made flange:connect the single and twin screw extruder.
