When the amount of ore feed is significantly insufficient, the sound of the impact of the liner and the steel ball will occur, resulting in the loss of the grinding medium and the liner.

When the amount of ore is unchanged, the increase or decrease of the particle size of the ore will also produce a similar phenomenon as when the amount of ore is large or reduced.

Therefore, during normal operation of the LUM ultrafine vertical mill, it is necessary to ensure that the feed is uniform and the particle size is uniform, and it cannot fluctuate too much.

Only in this way can a good production index be obtained. Whether the LUM ultrafine vertical mill can be fed to the mine evenly depends on the operator’s constant observation.
