Introduction The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
Most existing pulverizers—both the verticalshaft and ballmill types—come with a static classifier. Its blades reject coarse particles to produce a stream of coal particles that are mostly ...

The Ball mill pulveriser is basically horizontal cylindrical tube rotating at low speed on its axis, whose length is slightly more to its diameter. The inside of the Cylinder shell is fitted with heavy cast liners and is filled with cast or forged balls for grinding, to approximately 1/3 of the diameter. Raw coal to be ground is fed from the ...
Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
