How to solve the problem of spits in coal vertical mill? 1. Theoretically speaking, if the wind speed of the nozzle ring of the coal vertical mill is sufficient, the mill will not discharge slag, it will only be full, and finally the vibration will stop. However, in actual production, the wind speed of the nozzle ring cannot be increased indefinitely, so slag discharge occurs.
