1. Introduction of Product

SHJ(D) Series Co-rotating Twin Screw Extruder Used For PVC,PE.PP,ABS,EVA,PET

Designed by CAD, the closely intermeshed screw elements have excellent self-wiping characteristics, and can be interchanged with each other easily. Our over many years of experience in screw design and software development enable us to realize efficient solids conveying, melting/plasticizing, mixing/compounding, dispersing, homogenization, devolatilization, pressure-buildup in twin-screw extruders, in accordance to the specific requirements of each process. To meet the increasingly demanding challenges from new materials and new processes, we are providing new types of screw elements accordingly. Screw elements are slid onto a spline shaft to achieve higher torque and higher screw channel volume for even higher throughput.

2. Description:

For most applications, the core shaft is made of 40CrNiMoA, the screw components are made of highly quality high speed tool steel, W6Mo5Cr4V2, that receives heat treatment with vacuum hardening at high temperature, whole hardness: HRC62-64. the barrel body is made of 45# steel, and the”∞”shaped hole is lined with wearing proof alloy a-101(Fe-Cr-Ni-B+Carbide), hardness HRC60-64. For applications with particular requirements, high corrosion-resistant and high wear-resistant materials of construction with special heat treatments are also provide for our customer to choose.

The key components in the electric control system are all imported very reliable instruments, providing interlock control system only after the oil lubrication system interlocks with the host machine, i.e., the oil pump start up, can you start up the host machine;  only after the feeding system interlocks with the host machine, i.e., the host machine starts up, can you start up the feeding machine. When the pressure interlocks with the host machine, i.e., reaches overpressure, both the host machine and feeding machine should stop operation; When the electric current interlocks with the host machine, i.e., reaches overcurrent, both the host machine and feeding machine should stop operation. Simulating control panel, PLC control, and PCC control are also provide upon request beside the standard control model.

Due to its low vibration and low noise level, the main extruder can be installed on most solid grounds with no need for any special base.

3. Equipment list

1.DC motor 110KW 

Transmission: Three axis parallel design , The part of deceleration and  torque divider are all in one.

Bearing: SKF Band    Oil lubrication  Inlet oil sealing device

We use spring pin to avoid overload and over current on drivetrain. We can also avoid overload and over current by connecting the main computer board of frequency converter which is imported.

2. 9 pieces of Wear-resisting bimetal barrel(the inner wall is made of wear-resistant alloy)

The Component of screw is made of High-Speed Tool Steel( W6Mo5Cr4V2). The material of Spindle is 40CrNiMo. Component and Spindle of screw are connected by the function of involute spli
