Technical Parameters

KY-75 Co-Rotating Parallel Twin Screw Extruder

1.Main Motor：

1.1 Manufactured by WanNan motor factory;

1.2 AC motor, power 55KW;

1.3 Cooling mode; Fan cooling; Environment temperature≦40℃; Install Height≦1000m;

2. Gearbox：

2.1 New structure gearbox, high torque, high speed;

2.2 Splined sleeve to connect with the Screw;

2.3 Use imported brand bearings. Integrated thrust bearing for load sustainability

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

2.5 Speed: 100 – 400RPM.

3. Barrel：

3.1 The barrels are made by manufacturing center and the aligning pin and inner hole are completed by manufacturing center in one time. Inner hole is 6 grade 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;

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

3.3 The barrels are produced with bimetallic alloy cover：HRC60-62;

3.4 The barrels (except feed barrel) adopt cast-aluminum heaters. The barrels use soft water cooling.

3.5 The first (1) barrel is feed barrel, the fifth (5) barrel is extrusion barrel and the rest barrels are closed-mouth barrel.

4. Barrel Temperature Control System：

4.1 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 c1 and control the flow by stop ℃ valve;

4.2 Two cooling water pipes. All the cooling pipes and joints are of stainless steel.
