Description

Technical Field

[0001] The utility model belongs to the field of ore crushing, in particular to a manganese ore crushing device. Background Art

[0002] Traditional crushing devices use pairs of crushing rollers to crush large pieces of ore into particles. In order to improve the crushing effect, at least two pairs of crushing rollers are usually set at different heights, and the large particles of ore that have not been completely crushed are re-introduced into the feed port through a screen and re-enter the cycle. However, under the crushing of crushing rollers at different levels, some of the ore is directly crushed into tiny particles. If the small particles are re-introduced into the next level of crushing rollers or re-introduced into the feed port, it will prevent the crushing rollers from crushing the original large particles of ore, reducing the crushing efficiency.
