Technical Parameters

Configuration Of KY-65 Co- Rotating Parallel Twin Screw Extruder Machine Group

1. Main Motor： 1.1 Manufactured by WanNan motor factory; 1.2 AC motor, power 90KW, rpm 600r/min; 1.3 Cooling mode; Fan cooling; Environment temperature≦40℃; Install Height≦1000m;
2. Gearbox: 2.1 New structure gearbox, high torque, high speed; material of gearbox is QT450; 2.2 The gear is grade 6, which is a high precision. High speed overloading hard-tooth surface. The materials are 20CrNi2MoA and 20CrMnMo,carburizing heat treatment of gears HRC60-62; 2.3 Involute gear teeth couplings between the output shafts and screw shafts; 2.4 Use imported brand bearings. Integrated thrust bearing assembly is Name Luoyang. 2.5 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 Forced feeder, with Nidec inverter; 3.2 AC motor, power 1.5kw;
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 Screw elements use Involute to connect; 4.3 Screw element diameter: 62.4mm; L/D=44:1; numbers of barrels:11; 4.4 Screw rotating speed: 600r/min. 4.5 Material of screw element: 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 is bimetal integral alloy sleevet: 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 (1) barrel is feed barrel, the sixth (6) barrel is nature exhaust, the tenth (10) barrel has vacuum exhaust mouth, the eleventh (11) is extrusion barrel and the rest are closed barrels.
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.
7. Vacuum System: 7.1 External stainless steel vacuum condensation pot; 7.2 Water ring vacuum pump, motor power 1.5kw; 7.3 Field pipe layout;
