Aug 29, 2010· Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
Coal mill in thermal power plant mill pulverizer in thermal power plants slideshare specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh a 70 coal sample passing through a 200 mesh screen indicates optimum.
