What Are The Technical Challenges Of Twin-screw Extruders?

The twin-screw extruder is divided into an engaging type and a non-engaging type according to the relative positions of the two screws. The mesh type is divided into a partial mesh type and a full mesh type according to the degree of meshing. The twin-screw extruder is divided into two types: the same direction rotating screw and the reverse rotating screw according to the screw rotating direction.
