1.The first phase is TSE twin screw extruder with no die.Via the mix of barrel and screw, the extruder can exert its strong potential to make the thermo sensibility content like PVC melting, compounding,dispersing and decentralizing below the problem of no back strain
2.The CZPT stage is SJ one screw extruder.Simply because of the lower rotating velocity, it can complete melting,compounding lengthways and forming srands steadily, avioding above heating.

Two stage air cooling extruders
Blend the large pace and extensive mixing of processing and the low pace, low temperature, and low shear of one screw processing
Best for compounding of warmth and shear-sensitive materials.
PVC compounds for cable, shoe sole, transparent container, and medical purposes EVA shield cable compounds
CZPT black master batches of PE, EVA, and so forth.
Detailed knowledge for SP75-a hundred and eighty:
one.Main extruder:TSE-seventy five/500-one hundred ten–32
one) CZPT diameter: 71mm. L/D = 32
2) Main drive motor: AC 110Kw, Speed regulated by ABB transducer imported from Switzerland.
three) CZPT rotary speed: 50~500rpm
4) The barrels are equipped with bimetallic liners (45#metal+α101), processing heat treatment. HRC=sixty~sixty two. The material of screw elements is high-speed steel 38CrMoAlA, nitrogen treatment. HRC=fifty eight~60.
five).The 1st barrel is the main feeding vent, the 6th is for degassing, 9th is vacuum section , and the others are closed barrels.
six)Casting copper heaters for 2-3th barrels. The others are equipped with casting aluminum heaters. All heating power: ~50kw.

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
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-a hundred and eighty/85-ninety-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)Drinking 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.
7)Tailor-made flange:connect the single and twin screw extruder.
