The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Pulverized coal fired boilers the total losses account to about 12 to 14 . Roughly 50 of the losses can be tuned to the optimum and the other 50 is governed by fuel properties like hydrogen in fuel moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

Pulverizer capacity is not simply a measure of coal throughput capacity refers to a certain coal throughput at a given fineness raw coal sizing HGI (Hardgrove Grindability Index) and moisture
