Title: Crushing device
Inventor: SATOU KAZUNORI
IPC: B02C15/00
Filed: 1993-02-05
Abstract: PURPOSE:To obtain a roller mill which is vibration-free and can be used in a wide load range and for various types of carbonaceous materials by forming some of the segments of a crushing roller using a different type of material in terms of abrasion resistance and hardness from that of other segments, and aligning the segments irregularly in a peripheral direction. CONSTITUTION:In a crushing device which crushes a raw material 1 using crushing rollers 4, some of the segments 5 of the crushing roller 4 are formed in a material which is different in terms of abrasion resistance and hardness, from that of the other segments 5, and are aligned irregularly in a peripheral direction. Consequently, abrasion advances differently, if a material with different abrasion resistance and hardness is used. Therefore, the shape of a crushing face varies depending upon the segment 5. This shape variation occurs not only in the segment 5 of the crushing roller but also in the segment 13 of the crushing ring. Then the shape of the crushing face changes irregularly, and the irregular alignment varies according to each crushing roller 4. Thus the self-synchronization of the precession of the crushing roller 4 is inhibited and does not develop to a self-excited vibration.
