The VRM for cement grinding offers a significant advantage in power savings. Typically, the VRM uses 50% less power than a ball mill when grinding the same clinker to 3900 Blaine. VRMs are also much more adept at handling hot feed compared to ball mills.The simple and compact vertical mill layout is cost competitive to build and offers many options for layout, even in existing plants.

Coal Grinding - Cement Plant Optimization

Mill explosions will only occur when three conditions exist: sufficient oxygen (≥12 per cent O 2-in-air), the presence of an ignition source (>30mJ) and air-suspended coal dust in a bandwidth of 50-2000g/m 3. Safe operation of coal mills seeks to avoid these conditions and many monitoring systems exist to provide fire and explosion protection.
