COAL HANDLING SAFETY - AMETEK Land
If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.

Similarly mills are normally designed for 55 Hardgrove index and harder coals (lower HGI) will result in derating. Finally, a 10% fall in capacity between maintenance is assumed and allowed for in sizing a coal mill.
