two systems when used for grinding cement. It has to be remembered that there are major differences in the mech- anism of grinding between VRMs and ball mills, in terms of how grinding occurs, the residence time, the level of repeat grinding and recirculation factors, among others. In a VRM, comminution occurs by.
The material to be ground is fed into the mill from its top. It falls on the table placed at the bottom of the mill. Due to the centrifugal force generated by the rotation of the main shaft the grinding rollers are pressed closely upon the grinding ring and grind the material fed into the mill (raw, cement or coal for instance) as they roll.

pressure difference between inlet and outlet, the grain size of the raw material [1, 2]. For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated. Using G=K * D 2.51. Where, G is.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
