A drive unit is provided in order to rotate the drum and the crushing roller. The drum is mounted so that it can rotate on a base 11. The crushing roller 30 is mounted so that it can rotate and is adjustable by means of two fixing units 70 actuated hydraulically, which hold two ends of the shaft 31 of the crushing rollers 30. The crushing machine makes it possible to carry out efficient and improved crushing, and to obtain selectivity corresponding to a desired object size range. <IMAGE>
