The ore feeding of the ultrafine vertical mill is mainly through the ore feeding department. The main function of the ore feeding department is to quickly feed the materials and graded return sand into the ultrafine vertical mill.
The ultrafine vertical mill must ensure uniform ore feeding during the operation of the concentrator. The so-called uniform ore feeding means that the ore feeding quantity is stable and the ore feeding particle size composition is unchanged.
So how important is uniform feeding of ultrafine vertical mill? If the ore is not fed in proportion, the particle size of the mill product will become coarser and the return sand will increase under the condition of appropriately increasing the ore feeding amount.
