This is a picture of one side of an attrition mill that is being serviced. Notice the inlet chute where the coal drops down the chute into the mill and also notice the green motor that drives the mill and blower. When the coal is finely ground it moves to the blower section to the left and is conveyed up the round pipe to the boilers.

COAL BASED THERMAL POWER PLANTS: COAL HANG UP IN BOWL MILLS
· 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 vertical roller mill failure problems
· If the coal is not sufficiently dried, it will be adsorbed inside the vertical mill and the pulverized coal pipe, which will block the pulverized coal pipe or cause the vertical mill and the pulverized coal pipe to ch fire. Solution: Reduce the coal feed rate, maintain the outlet temperature, and recheck the ventilation control system. 3.
Coal Grinding
Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
