 · A higher Hardgrove index indies 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.

Advantages: • Coal feed and coal air ratios to individual burners are under direct control. • Less mill capacity is needed. The pulverising mill grinds the coal at a steady rate irrespective of boiler feed. • There is always some coal in reserve. Thus any occasional breakdown in the coal supply will not effect the coal feed to the burner.
