Abstract (en)
[origin: EP0319779A2] The screw mill (1, 2) consists of two motor-driven screw conveyors (14, 15) mounted rotatably in a housing (17). The screw conveyors (14, 15) are divided into two sections. The first section is designed as an interacting screw conveyor pair lying in a common working chamber, while in the second section the screw conveyors (14, 15) lie in separate working chambers and form separate outputs (23). As a result, the occurrence of lateral forces is avoided on the one hand and, because of the absence of throttles in the working chambers, a high processing capacity is achieved on the other hand. <IMAGE>
