As one of leaders of impulse piping schme of coal mill industry, SBM always seeks innovation & excellence.
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.

A steam valve closure increased the pressure about 20 percent, which was sufficient to fail a 90° elbow in the balance-of-plant (BOP) portion of the 18-inch feedwater line. A section of pipe about two feet by three feet blew out resulting in complete separation. The reaction forces moved the pipe about six feet.

After being crushed, the coal is elevated to the belt conveyor and sent to the raw coal bin further. Then the coal is fed into the grinding cavity of LM130M vertical mill by quantitative belt conveyor. After being ground, the coal gets pulverized and enters to the anti-explosive impulse dust collector in the wake of powder separation.
