    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.VIBRA-DRUM Grinding Mills excel over conventional ball, stirred media, or vertical roller mills in both grinding and energy efficiency. The features listed below highlight why our mills are so effective and efficient. Proven energy savings range from 35 to 50 reductions in kW hours per ton of processed material. 5 to 10 times longer media life.
