Operation Guide for Vertical Roller Mill in Cement Plant ...

The Material Layer of The MillThe Vibration of The MillThe Grinding Pressure of The MillThe Gas Temperature at The Discharging PortThe Air Volume in The MillThe Hot Gas from The KilnA stable material layer with proper thickness is indispensable for the well functioning of the vertical roller mill. Too thick material layer will reduce the grinding efficiency of the vertical roller mill. When the pressure difference of the mill reaches the limit, the material layer will collapse and affect the operation of the main motor and the discharge system. Too thin material layer will cause the mill to generate stronger driving force and damage the rollers, millstone, and hydraulic system of the mill.
