Classification of screw extruders and their differences

According to the classification of plastic extruders, it can be divided into: twin-screw extruders and single-screw extruders, as well as multi-screw extruders and non-screw extruders that are not commonly seen.

The difference between a single-screw extruder and a twin-screw extruder: one is a screw, and the other is two screws, both of which are driven by a motor, and the power varies with different screws. The power of 50 cone twin is about 20KW, 65 is about 37KW, the output is related to the material and screw, the output of 50 cone twin is about 100-150KG/H, the output of 65 cone twin is about 200-280KG/H, the output of single screw is only half.

Extruders can be divided into single-screw, twin-screw and multi-screw extruders according to the number of screws. At present, the twin-screw extruder is the most widely used, suitable for extrusion processing of general materials. The twin-screw extruder has less heat generated by friction, relatively uniform shearing of the material, large screw conveying capacity, relatively stable extrusion volume, long residence time of the material in the barrel, and uniform mixing. SJSZ series conical twin-screw extruder has the characteristics of forced extrusion, high quality, wide adaptability, long life, low shear rate, difficult decomposition of materials, good mixing and plasticizing performance, direct molding of powder materials, etc., with automatic temperature control, Vacuum exhaust and other devices. It is suitable for the production of pipes, plates, special-shaped materials and other products.
