LUM ultrafine vertical mill feeds mainly through feeding materials to the mine department, and the main function of the feeding department is to quickly feed materials and graded returned sand into the LUM ultrafine vertical mill.
During the operation of the LUM ultrafine vertical mill, it is necessary to ensure uniform ore feeding. The so-called uniform ore feeding means that the number of ore feeding is stable and the particle size composition of the ore feeding remains unchanged.

So how important is the uniformity of the LUM ultrafine vertical mill? If the ore is not fed in proportion, if the feeding amount is appropriately increased, the grain size of the mill product will become coarser and the amount of returned sand will increase.
