To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed.

The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...
The four most common coal pulverizers types are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. …
The mill filling should be measured at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining.
