According to the number of screws, it can be divided into single-screw, twin-screw, triple-screw, and multi-screw. Twin-screw can be divided into parallel twin-screw and conical twin-screw. The most significant difference between parallel and conical twin-screw extruders is the screw machine. The geometry of the cylinder is different, which leads to many differences in structure and performance. Although the characteristics of the two are different, they have their own advantages.
