The important elements of pulverizer performance are fineness, fuel distribution, coal (pyrites) rejects, and primary airflow calibrations. Optimizing pulverizer performance is a prerequisite for optimum furnace combustion. About three-fourths of the 13 Essentials are pulverizer, primary air, and fuel line related. The pulverizers are truly the ...
Vertical roller mill can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. Grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill. Application

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.

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.
