Coal slurry is prepared by wet grinding the coal in a rod mill. Coal is delivered by conveyor into the rod mill feed hopper. The coal has to be ground to the right particle size and size distribution in order to form a stable coal/water slurry at optimum slurry solids concentration, which is typically about 60 to 65% by weight.

In a coal handling system, crushing is limited to a maximum size of 6 or 4 mm. The most commonly used devices for crushing are the rotary breaker, the roll crusher and the hammer mill. Coal must be screened before crushing so that only oversized coal is fed to the crusher. This helps to reduce power consumption in the crusher.

Coal is transported to bowl mills by coal feeders. 3. Bowl Mill The coal is pulverized in the bowl mill, where it is grounded to a powder form. The mill consists of a round metallic table on which coal particles fall. This table is rotated with the help of a motor. There are three large steel rollers, which are spaced 120" apart.
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.
