ABSTRACT:
A screw mill comprises two motor-driven conveyor screws mounted in rotary manner in a casing. Each of the conveyor screws is subdivided into two portions. A first portion is constructed as a cooperating conveyor screw pair located in a common working area, while in a second portion the conveyor screws are located in separate working areas and from separate outlets. On the one hand, this avoids the occurrence of lateral forces and, on the other hand, due to the lack of constrictions in the working areas, ensures a high processing capacity.
