SP compounding PVC extruder machine:

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.

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

1)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.
