A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants

The relationship between coal size reduction and energy input is a nonlinear curve, so it is difficult to represent coal grindability with a single numerical value. However, M ′ f mat. ′ is more appropriate than HGI to measure coal grindability.

Hardgrove grinding mill coal - Crusher Unit. capacity falls when grinding coal with a lower hgi the curve shows variation in mill, hammer mill, coal, on the grinding in hardgrove mill, a t20wn torque .

The straight end disc design provides significant advantages: simple liner plate shape, quick replacement of the mill lining and free design of the mill inlet and outlet to suit process requirements instead of structural constraints. The ring motor transmits the motor torque to the coal mill accessories shell through a magnetic gap.

Failure of a ball and race type coal pulverizer mill shaft has been analysed. It was found that the shaft, made of EN 25 steel, failed by fatigue.
