PROBLEM TO BE SOLVED: To feed a large amount of a material to be crushed timely into a compressor and to perform compression work efficiently by controlling the number of revolution of the cutters of a crusher by making it variable. SOLUTION: A lifting transportation conveyer 2 is installed on the outlet side of a crusher 1 for crushing refuse, etc., by the engagement of cutters. A crushed material 3 of refuse, etc., is mounted on the conveyer 2 and fed into a compressor 5 which works by the forward/backward movement of a press cylinder through a feed member 4 placed at the upper end of the conveyer 2. Since the conveyer 2 is moving always at a constant speed, when the press cylinder is stopped, the rotation speed of the cutters of the crusher 1 is increased, and a large amount of the material 3 is mounted on the conveyer 2. When the press cylinder retreats after a compression process, the rotation speed of the cutters of the crusher 1 is decreased, and the amount of the material mounted on the conveyer 2 is reduced. |
