The input mass flow of the raw coal to the mill is difficult to measure as well; typically, the conveyor belt speed is used for this purpose. Additionally the varying coal quality, e.g. Hardgrove Grindability Index (HGI) and moisture, of coal fed to the mills varies, and general mill wear cause parameter changes (Fan, Rees, & Parker, 1997). Due ...
