 · 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.

Consider the case of a cohesive coal of bulk density ρ = 1 t/m³ which has a measured adhesive stress of σ. o = 1 kPa for contact with mild steel, a typical value. The coal is attached to the underside of mild steel surface as illustrated in Figure 8. A vibrator is proposed as a means of removing the coal.

 · 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.
