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 capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM
2. VRM mill can remove more than 20% moisture . 3. Vertical roller mills plants use less space . 4. Grinding plants VR mills have lower specific energy consumption 5. VRM are more flexible, the capacity can easily be varied from 40 to 100% of the nominal capacity. 6.

The FL vertical roller mill was chosen to produce a full range of cement types at the Muktarpur Plant. Driven by two 5.8 MW FL MAAG Max Drive gear systems, the impressive mill is the biggest VRM ever to be installed in a cement plant in terms of dimension, operating capacity and installed power.
Vertical roller mills 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.
