Technical data for TSE-52 twin screw extruder:

1) Screw diameter: 51.5mm. L/D = 40

2) Main drive motor: AC 55Kw, Speed regulated by ABB transducer imported from Switzerland.

3) Screw rotary speed: 50~500rpm

4) Screw shaft is made of high-strength alloy 40CrNiMoA.

5) The barrels are equipped with bimetallic liners (45#steel+α101), processing heat treatment. HRC=60~62. The material of screw elements is high-speed steel W6Mo5Cr4V2, nitrogen treatment. HRC=58~60. The barrels includes feeding section, degassing section and close section.

6) Length of each barrel is 210mm, totally 10 pieces of barrels.

7)The 1st barrel is the main feeding vent, the 6th is for degassing, 9th is two screw extruders for the production of modified starch section , and the others are closed barrels.

8)Casting copper heaters for 2.3th barrels. The others are equipped with casting aluminum heaters. All heating power: ~30kw.

9) 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 sump

10) 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.
