The basic structure of single screw extruder mainly consists of the transmission system, feeding system, extruding system, heating system, and cooling system, as well as nose and mouth molds.

Transmission System The transmission system, whose purpose is to achieve the required torque and uniform RPM of the screw, is an important part for extruder to complete the extrusion process under specific conditions (such as die head pressure, screw rotation, extrusion, temperature, etc). The transmission system is composed of motor, reducing unit transmission and bearing system.
