• Axis of the roughened disks may be horizontal or vertical • One plate is stationary and fixed with the body of the mill while the other one is rotating disk • Material is fed between the plates and is reduced by crushing and shear • Mills with different patterns of grooves, corrugations on the plates perform a variety of operations
the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is
