What is the classification of twin screw extrusion granulator?

by:TENGDA     2022-10-04

There are many different forms of twin-screw extruder granulator, the main difference is that the screw structure is different. The screw structure of the twin-screw extruder is much more complicated than that of the single-screw extruder, because the screw of the twin-screw extruder also has rotation direction, degree of meshing, etc.


The twin-screw extrusion granulator commonly used in the extrusion of PVC profiles is usually tightly meshed and counter-rotating screws, and a small amount of co-rotating twin-screw extrusion is also used, but usually only at low speed, about 10r /min range. The high-speed meshing co-rotating twin-screw granulator is used for mixing, exhaust granulation or as a continuous chemical reactor. The maximum screw speed of this type of extruder ranges from 300 to 600 r/min. The conveying mechanism of the non-intermeshing extruder and the intermeshing extruder is very different. Compared with the conveying mechanism of the single-screw granulator, the two are essentially different.


The twin-screw extruder granulator is composed of several parts such as a transmission device, a feeding device, a barrel and a screw, and the functions of each part are similar to that of a single-screw granulator. The difference from the single-screw granulator is that the twin-screw extruder has two parallel screws placed in the same barrel.
