The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system ...

Hence the mill capacity varies inversely with the size of the raw coal. Using smaller size raw coal feed to mill to increase the milling capacity only shift the workload to the raw-coal precrusher.Normally optimum coal size is selected so that total initial, operating and maintenance cost of precrusher and mill can be kept minimum.

All mill capacities are based on a standard coal with HGI = 50. The larger the value for HGI, the easier it is to grind the coal, resulting in a higher mill capacity. An HGI of 35 reduces the mill capacity about 20%. Coals with HGI less than 35 can be pulverized, but mill capacities are reduced significantly.
