Single screw pump extruder which can be divided into paragraphs screw
Single-screw pump extruder which can be divided into several sections of the screw, each section of the screw in the structure of the characteristics of each section of the material on the role of the screw can be divided into three sections: (deep tank) feeding section, (compression) Transitional section, (shallow trough) metering section. The feed section must be deep enough to hold the low bulk plastic particles, produce the necessary torque to deliver solids, and generate enough pressure to compress the particles into the solid bed. Much of the melting pump occurs in the relatively long compression section, reducing the groove depth to improve the melting efficiency. The metering section shallow trough can homogenize the melt reasonably, the melt pump comes from the partial melting zone of the melting zone and can bring more uniform temperature to these partial melting zones.
