    Nov 13, 2020· 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.
