PURPOSE: To crush efficiently by combining the crushing utilizing impact and the crushing by blowing in the crushing of a raw material ore.
CONSTITUTION: A raw material ore fed from a feed opening 13 above a rotor 1 is accelerated at a dead space, and the accelerated raw material ore is discharged out of a discharge outlet 40. At that time, a part of the raw material ore is guided to an inclined face 45 of a lower liner 44 and discharged facing upward in the radius direction. The discharged raw material ore is struck against an impact face of an anvil 51. After that, a part of the raw material bounded back is struck by a striker 30 of the rotor 1 and crushed. On the other hand, when the wear of a wear ring 20 increased to the degree of reaching a mounting pin 22, the wear ring 20 is removed from the mounting pin 22 and rotated, and an unworn section is faced to the side of a discharge line 40 and remounted.
