Vertical roller mill 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. 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. Application:
The developed automation and optimization system was installed at a number of ball mills at TPSs for grinding the coal, at cement plants for grinding the clinker and at ceramic plants for grinding the clay. One of the systems was installed at a TPS with a 300 MW power generating unit where three ball mills were used for coal grinding.
