進される。The casing has a tubular portion on the downstream side of the inlet corresponding to the feeding direction of the spiral body,
The tubular portion accommodates therein an extension portion of the rotary shaft, and the extension portion of the rotary shaft is a pre-separated portion formed of a plurality of spirals near the inner surface of the tubular portion. If it has a body, the debris crushed by the spiral body in the tubular portion on the downstream side of the casing is made finer and the grain size is made more uniform by the pre-peeling body consisting of a plurality of spiral bodies adjacent to the inner surface thereof. It is crushed into pieces and the relative rotation of the inner surfaces and the plurality of spirals in close proximity to each other increases the resistance to the movement of the strips and promotes the pre-separation of the gypsum and the paper.
