<p>This invention relates to a device for cutting up materials comprising a first and a second shaft (1, 2) which are mounted substantially parallel to each other, and which are provided to rotate in opposite directions. The first shaft (1) has a higher rotation speed than the second shaft (2). On each shaft (1, 2) cutting wheels (3, 4) are mounted alternating with intermediate rings (5, 6), the shafts (1, 2) being positioned in such a way that the first cutting wheels (5) on the first shaft (1) are situated between the second cutting wheels (6) on the second shaft (2). During rotation the first cutting wheels (3) on the first shaft (1) come into contact with the second intermediate rings (6) on the second shaft (2) and the second cutting wheels (4) on the second shaft (2) come into contact with the first intermediate rings (5) on the first shaft (1). The first and second cutting wheels (3, 4) have such a number of cutting teeth (7, 8) that the cutting teeth of the first and second cutting wheels move past each other. <IMAGE></p> |
