The structure of twin screw granulator

The transmission system in the twin-screw granulator, its function is to drive the screw, during the extrusion process, to supply the required rotational speed and torque of the screw, which is usually composed of bearings, motors and reducers. The screw is the main structure of the plastic granulator, which is related to the production efficiency of the plastic granulator. It is made of corrosion-resistant, high-strength alloy steel.

The hopper is equipped with a cutting device at the bottom, which can cut and adjust the material flow, and is equipped with a calibration metering device and an inspection hole on the side. Machine head and mold, the machine head is used to convert the plastic melt from rotary motion to parallel linear motion, smoothly and evenly introduce it into the mold sleeve, and give the plastic a certain molding pressure; the machine head is made of carbon steel jacket and alloy steel. The inner sleeve is formed, and the formed mold is installed in the machine head. The barrel is usually made of pressure-resistant, heat-resistant, high-strength, corrosion-resistant, strong and wear-resistant alloy steel or a composite steel pipe lined with alloy steel. It is a metal cylinder. During operation, the barrel and The screw can realize the crushing, melting, plasticizing, softening, etc. of the plastic, and can continuously and evenly convey the rubber material to the molding system.
