In addition to the requirement by NFPA 85 for inerting a tripped mill system, coal mill OEMs usually recommend that a mill system be inerted during both the normal mill start up and shut down process. Steam is commonly employed in the power industry for coal pulverizer system inerting, due to its ready availability and cost effectiveness.

Dec 13, 2011 A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.
