The attributes
1.The first stage is SHJ twin screw extruder without die.By way of the blend of barrel and screw, the extruder
can exert its powerful capability to make the thermo sensibility substance like PVC melting, compounding,dispersing and
decentralizing beneath the condition of no again force
two.The CZPT stage is SJ one screw extruder.Since of the decrease rotating velocity, it can full melting,
compounding lengthways and forming srands steadily, avioding in excess of heating.

Attributes:
Merge the substantial velocity and in depth mixing of processing and the reduced pace, reduced temperature, and low
shear of single screw processing
Excellent for compounding of warmth and shear-sensitive resources.
Application:
PVC compounds for cable, shoe sole, clear container, and medical apps EVA shield cable
compounds
CZPT black master batches of PE, EVA, and many others.

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
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-one hundred eighty/eighty five-ninety-22
one)180mm L/D = 28, rotary speed is 6~65rpm.
