Technical Field

[0001] This utility model belongs to the field of ore crushing, specifically, it relates to a raw material crushing device for ore sorting. Background Technology

[0002] A raw material crushing device for ore sorting is a device that crushes large pieces of ore to a target particle size using mechanical force, aiming to provide raw materials with uniform particle size and sufficient liberation for subsequent mineral processing.

[0003] The prior art discloses the field of ore crushing technology (CN202220982897.2), specifically relating to an ore crushing device. The ore crushing device includes a crushing box, at least one set of first crushing rollers, and at least one set of second crushing rollers; both the first and second crushing rollers are rotatably connected within the crushing box, with the first crushing rollers positioned above the second crushing rollers; each set of first crushing rollers includes two first crushing rollers, the rolling surfaces of which are spaced apart and cooperate with each other for preliminary crushing of the ore and downward conveying of the ore; each set of second crushing rollers includes two second crushing rollers, the rolling surfaces of which are spaced apart and cooperate with each other for secondary crushing of the ore and downward conveying of the ore.
