It can be known from the working principle of the mill that the vertical mill grinds the material by applying pressure from the grinding roller when it is working. After a long time of operation, the grinding rollers and grinding discs become uneven and irregular due to abrasion, the grinding efficiency decreases, and the output decreases.
The grinding pressure is increased under the premise of ensuring stable pressure difference and layer thickness. Material grindability is an important factor affecting the yield. When material grindability deteriorates, grinding cycles number of vertical mill increases significantly.
