Further, the materials are fed by gravity and fall forward as the clearance between the rolls 7 and jaw 2 increases. The material trapped in the converging passage is crushed when the rolls 7 move to the jaw 2. The rolls 7 provide also a peristaltic pumping action that enhances the materials throughput as indied with arrow B.
