   Two-screw stem motor power 132KW DC

II.  Machine configuration:

       SHJ 95 twin-screw extruder

1.Gearbox

1)       Reduction factor: 3.75:1

2)       Output shaft rotation speed?MAX400RPM

3)      Input shaft rotation speed: MAX1500RPM

4)       The compact host machine features integrated speed reduction and torque transfer with a design of parallel three axles. SKF bearings are used in the reducer, torque transfer device and as the radial bearing in the output shaft.

2. Lubrication oil cooling system

1)       Motor of oil pump 1.1KW

2)       Lubrication oil model: Hai Brand 6402 made in Shanghai, mediums load gear oil, model: 85W/90GL - 4.

3)       Brand name: xi' an Oil Pump Plant

4)       Condenser model:SL - 415

5)       Lube oil pump model:CB – B16

3. Motor of host machine

1)       Motor of host machine: 132KW?DC motor)

2)       Motor speed ( MAX):1500RPM

4. Screw stem

1)       Screw stem diameter:?91mm

2)       L/D = 40:1

3)       Screw stem 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

5.Charging barrel

1)  The barrel body is made of #45 steel, and the "8" shape hole is lined with wearing proof alloy a-101?Fe - Cr - Ni –B +Carbide?, hardness: HRC60 - 64, barrel length: L = 360mm/section.

2)  The first cylinder is used for feeding materials, the 10th cylinder for extrusion, the 9th cylinder for vacuum and the other cylinders are of closed mouth type.

3)  Soft water circulation system

3.1 The barrel uses soft water cooling.

3.2 The soft water tank separates with the body, which facilitates cleaning and service.

10)  The electric control cabinet controls the temperature control system, the driving system and the interlock control system.

8. 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 overcurrent, both the host machine and feeding machine should stop operation.
