In modern thermal power plants coal grinding mills are an important and very frequent subsystem. As time passes the grinders in the mills become depleted and the functionality of these mills decreases. Because of that the mills need to be stopped periodically, every 1500 hours, so they can be checked and, if necessary, repaired.
The three grinding rollers, mounted in fixed position, are passed down on the table under hydraulic loading. Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track. Sectional View of the mill
Phrase one: raw material crushing Coal blocks will be crushed to 15mm50mm fineness by crusher. Phrase two: drying and grinding material with low moisture will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding. The hot air in the mill will dry the coal.
