What Is The Principle Of Single Screw Barrel Extruder

Posted by Admin | 04 Aug

Principle of Single Screw Barrel Extruder:

A single screw is generally divided into three sections in the effective length. The effective length of the three sections is determined according to the diameter of the screw, the pitch, and the depth of the screw. Generally, each is divided into one third; the last thread of the material port is called the conveying section: the material is required here Can not be plasticized, but must be preheated and compressed;

The second section is called the compression section. At this time, the volume of the screw groove is gradually reduced, and the temperature must reach the degree of plasticization of the material. The compression produced here is from the conveying section three, and here it is compressed to one. Some machines also change to complete the plasticization. The melted material enters the third stage; the third stage is the metering stage, where the material maintains the plasticizing temperature to supply the machine head, which is generally slightly higher than the plasticizing temperature.
