The classification of the extruder(2)

Single screw machine and twin screw machine: one is one screw and the other is two screws They are all driven by a motor The power varies with the screw. The power of 50 cone double is about 20kW and that of 65 is about 37KW The output is related to the material and screw. The output of 50 cone pairs is about 100-150kg / h and that of 65 cone pairs 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. Nowadays, single screw extruder is the most widely used, which is suitable for the extrusion of general materials. Twin screw extruder has the characteristics of less heat generated by friction, uniform shear of materials, large conveying capacity of screws, stable extrusion capacity, long residence of materials in the barrel, uniform mixing and so on.
