Technical Parameters

 

  HKY-75 Co-Rotating Parallel Twin Screw Extruder

1.Main Motor:

1.1 Manufactured by large motor factory in China: AC motor, power 110KW, 1500rpm;

1.2 Cooling mode: fan cooling; ambient temperature≦40℃; Install Height≦1000m;

 

 

2. Gearbox:

2.1 New structure gearbox, high torque, high speed;

2.2 Spline sleeves between the output shafts and screw shafts;

2.3 Use imported brand bearings; Integrated thrust bearing assembly is Luoyang Brand;

2.4 The bearing and gears are forced to adopt the immersion oil-lubrication system. Oil pump motor power 0.75kW;

★Before delivery, the gearbox has been filled with lubricate oil. Fill the lubricate oil to the oil level once it declines during transportation, fill. Set up the extruder only after confirmation of the commissioning personnel of our company.

 

3. Feeder:

3.1 motor power 2.2kw, Japan YASKAWA frequency inverter for the speed regulation system;

3.2 SS hopper;

4. Screw Elements:

4.1 Kneading blocks are made by CNC machining center, same size for different batches, with good replacement and self-cleaning quality;

4.2 Involute gear teeth connection for the screw elements;

4.3 Screw diameter: 71mm;L/D=36;barrel numbers:9;screw rotating speed:500r/min;

4.4 Material of screw elements: W6Mo5Cr4V2, hardness: HRC60-62。

 

 

 

5. Barrel：

5.1 The barrels are made by CNC machining center and the aligning pin and inner hole is completed by machining center in one time. Inner hole is grade 6, which is a high precision. After assembly, the concentricity error is 0.05mm, thus greatly enhance the self-cleaning of screw and reduce energy consumption;

5.2 The barrels are equipped with stainless steel integral shielding which are secure, good-looking and power frugal;

5.3 The barrels are lined with bimetal alloy liner,hardness,HRC60-62

5.4 The 2nd and 3rd barrels adopt cast-copper heaters. Other barrels adopt cast-aluminum heaters. The barrels use soft water cooling;

5.5 The first barrel is feed barrel and the rest are closed barrel;

 

 

 

 

 

6. Barrel Temperature Control System:

6.1 Heating and cooling is controlled by temperature control meter through the solid-state relay or electromagnetic valve, thus form a closed-loop system to control the barrel temperature. The temperature control accuracy is ±1℃ and control the flow by stop valve;

6.2 Two cooling water pipes. All the cooling pipes and joints are of stainless steel; Soft water circulation system, including heat exchangers, 0.75kw water pump, stainless steel external tank.
