Quotation and Configuration of SHJ-75B(44: 1) twin-screw extruder (underwater pelletizeing system)

I. SHJ75B technical parameters

Twin-screw extruder length-diameter ratio 44: 1

Twin-screw extruder motor power 132KW AC

II. Machine configuration

I)SHJ 75B twin-screw extruder

A. One set of SHJ-75B twin-screw metering feeder

B. Gearbox(high speed and high torque series)

1)Reduction factor 2.5: 1

2)Output shaft rotation speed: MAX600RPM

3)Input shaft rotation speed: MAX1500RPM

C. Lubrication oil cooling system

D. Motor of host machine

1)Motor of host machine: 132KW(AC motor)

2)Motor speed ( MAX): 1500RPM

E. Screw

1)Screw diameter: Φ 71mm, max. Diameter D=Φ 71mm, min. Diameter d=Φ 47mm, D/d=1.51, center distance: A=60mm, torque: T=1050N. M, torque coefficient: T/A? =4.86.

2)L/D =44: 1

3)Screw with modular structure

4)The screw core shaft is made of 40CrNiMoA, and the screw thread components connect with the core shaft in an involute curve, which features high intensity, large load, and easy disassembly and assembly.

5)The screw components are made of high quality high-speed tool steel, W6Mo5Cr4V2, that receives heat treatment with vacuum hardening at high temperature.

6)Whole hardness: HRC62-64

F. Charging barre

1. The barrel body is made of #45 steel, and the “∞ ” shape hole is lined with wearing proof alloy a-101(Fe – Cr – Ni -B+Carbide), hardness: HRC60 – 64, barrel length: L = 290mm/section.

2. The first cylinder is used for feeding materials barrel, 9th cylinder for vacuum barrel, the 10th cylinder for extrusion barrel and the other cylinders are of closed mouth type. And the concentricity of all barrel bodies is below 0.025mm.

3. Soft water circulation system

H. Heating system(0-400oC. )

Test the fusing temperature with the fusing temperature thermal couple, and test the materials pressure with the pressure sensor.

I. Vacuum Degasifier

J. Electrical control system

K. Interlock control system

1. Only after the oil lubrication system interlocks with the host machine, i. e., the oil pump starts up, can you start up the host machine.

2. Only after the feeding system interlocks with the host machine, i. e., the host machine starts up, can you start up the feeding machine.

3. When the pressure system interlocks with the host machine, i. e., reaches overpressure, both the host machine and feeding machine should stop operation.

4. When the electric current interlocks with the host machine, i. e., reaches over current, both the host machine and feeding machine should stop operation.

II)One set of cutting auxiliary machine
