Technical Parameters

HKY65 Twin Screw Extruder Granulator

1. Main Motor: 1.1 Made in China; 1.2 AC motor, 90KW power, 1500r/min speed; 1.3 Cooling method: Fan cooling; Ambient temperature ≤40℃; Installation height ≤1000m;
2. Gearbox: 2.1 New structure gearbox, high torque, high speed, gearbox material is QT450; 2.2 Gear precision is grade 6 (Chinese standard), belonging to high precision. High-speed, heavy-load hardened gear surface. Materials are 20CrNi2MoA and 20CrMnMo, gears are carburized and heat-treated to a hardness of HRC60-62; 2.3 The output shaft and screw shaft are connected by involute gears; 2.4 Imported brand bearings are used. The integrated thrust bearing assembly is named Luoyang. 2.5 Bearings and gears adopt a forced oil immersion lubrication system. Oil pump motor power is 0.75kW; 2.6 Body oil seal: Taiwan Hansheng brand; 2.7 Pipeline condenser, cooling area is 1.8 square meters;
3. Screw Elements: 3.1 The mixing blocks are manufactured by a CNC machining center, with identical dimensions across different batches, exhibiting good interchangeability and self-cleaning properties; 3.2 A helical gear connection ensures power transmission between the screw shaft and the screw elements; 3.3 Screw component diameter: 62.4mm; L/D ratio = 40; Number of barrels: 10 3.4 Screw speed: 600 r/min; 3.5 Screw component material: W6Mo5Cr4V2, hardness: HRC60-62.
4. Barrel: 4.1 The cylinder is manufactured by a CNC machining center, with the locating pin and inner hole completed in one operation. The inner hole is grade 6, ensuring high precision. After assembly, the concentricity error is 0.05mm, significantly improving the screw's self-cleaning ability and reducing energy consumption; 4.2 The cylinder is equipped with a stainless steel integral shield, ensuring safety, aesthetics, and energy efficiency; 4.3 The cylinder is a bimetallic integral alloy sleeve: HRC60-62; 4.4 The second and third barrels use cast copper heaters, while the rest use cast aluminum heaters. All barrels are cooled with soft water. 4.5 The first (1) barrel is the feed barrel, the sixth (6) is for natural venting, the ninth (9) has a vacuum vent, and the tenth (10) is the extrusion barrel.
