twin screw extruders have the extruder principles of single screw extruders: conveying solids, melting, pressurizing and pumping, mixing, stripping and degassing, but not easy. Research on twin screw extrusion theory began late, combined with its many types, complex screw geometry and complex extrus

Twin screw extruders are developed on the basis of single-screw extruders and have been widely used in the molding and processing of extruded products because of their good charging performance, mixing and plasticizing performance, exhaust performance, and extrusion stability. To understand the working principle of twin screw extruder, we must first have some knowledge of the structure of twin screw extruder. This article provides a brief introduction to the structure and principles of twin screw extruders.

The screw of the twin-screw extruder is a building block combination. The combination of the entire screw should be selected according to the specific formula, material characteristics, mixing requirements and operating conditions.

In general, the extrusion process experienced by the material in the twin-screw barrel generally includes: feeding, melting, melt conveying, mixing, homogenization, exhausting, metering, and the like.
