Product Description

The characteristics
1.The first stage is SHJ twin screw extruder without die.Through the combination of barrel and screw, the extruder
can exert  its strong ability to make the thermo sensibility material like PVC melting, compounding,dispersing and
decentralizing under the condition of no back pressure
2.The second stage is SJ single screw extruder.Because of the lower rotating speed, it can complete melting,
compounding lengthways and forming srands steadily, avioding over heating.

Features:
Combine the high speed and extensive mixing of processing and the low speed, low temperature, and low
shear of single screw processing;
Ideal for compounding of heat and shear-sensitive materials.
 
Application:
PVC compounds for cable, shoe sole, transparent container, and medical applications EVA shield cable
compounds;
Carbon black master batches of PE, EVA, etc.

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.
