Machine configuration

A SHJ-35 twin-screw extruder, length-diameter ratio 40:1; power of the main motor (AC): 18.5KW.

1,SHJ-35 twin-screw metering feeder.

1) Feeding motor is an AC motor, main feeding motor power: 0.75KW.

2) Regulating system isDANFOSS inverter.

3) Reduction ratio: 17:1

4) The motor and reduction machine are straightly connected. The feeders with horizontal agitator can steadily feed and not to be bridge formatted. Both the feeder and hopper are stream-lined. Thus, it is easier to feed and wipe.

2. Gearbox

1) Reduction factor: 2.5:1

2) Output shaft rotation speed: MAX600RPM

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. Imported bearings are used in reducer, torque transfer device and as the radial bearing in the output shaft.

3. Lubrication oil cooling system

1) Motor of oil pump: 0.55KW

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

3) Condenser model: SL-303

4) Lube oil pump model: NB-B10

4. Motor of host machine

1) Motor of host machine (AC motor): 18.5KW

2) Motor rotating speed (MAX): 1500RPM

5. Screw

1) Screw diameter: 35.6mm

2) L/D: 40:1

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, which receives heat treatmentwith vacuum hardening at high temperature.

6) Whole hardness: HRC58~62

6. Charging barrel

1) The barrel body uses water-cooling and is made of #45 steel, which is lined with alloy bush,barrel length: L=150mm/section, 10 sections in total.

2) The first cylinder is used for feeding materials barrel, 6th cylinder for exhausting barrel equipped with exhausting block, 9th cylinder for vacuum barrel, the 10th cylinder for extrusion.

3) The other cylinders are of closed mouth type.

8. Vacuum degasifier

1) SK-0.15 water ring vacuum pump. Zibo Lianyi Vacuum Pump Factory

2) Motor for driving power: 0.75KW (AC)

3) Air suction amount (MAX):0.9m3/h

9. Soft water circulation system

1) The barrel uses soft water cooling.

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

3) Electromagnetic valve imported from Italy.

4) Water pipe is copper pipes coated with chrome.

5) Cooling method: water cooling.

6) Water cooling pump: 0.55 KW

10. 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.

11. Screen changer system

Manual screen changing

12. Die

Die equipped with manual quick-operating hinge screen changer.

13. Auxiliary system for pelletizing

1) Stainless steel tank: 400mm*3m(4 sets of tank spare parts) one set

2) Air knife (0.75KW) one set

3) Power of LQ-60 pelletizer motor (2.2KW) one set

B. Electrical control system

1) 3 phase 380V, AC 50 Hz.

2) Main electric control components areCHNTproducts.

3) Control buttons areCHNTproducts.

4) The main motor is an AC motor with a power of 18.5KW.

5) The speed regulator in the host machine isDANFOSSinverter.

6) The speed regulator in the feeding machine isDANFOSS inverter.

7) The temperature control meter is the Japan RKC product which is intelligent.

8) Pressure meter range: 0-25Mpa.
