Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.

The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed decreases with mill size and remains constant for a given mill diameter.

Bowl Mill: The most widely used mill for grinding coal. The raw coal is fed into the center of the mill. This is an intermediate speed pulverizer. The vertical shaft rotates at a speed 30 – 50 rpm. Specific power consumption 12 kWh/ton.

speed, ie a small reduction in speed can make a big reduction in the energy consumption. A fan running at half speed consumes as little as one eighth of the energy compared to one running at full speed. By employing VSDs on fans instead of dampers and vanes, the energy bill can be reduced by as much as 60 percent.

The hammer mill was evaluated at three sieve holes diameter (4, 6 and 8 mm) and three levels of corn moisture contents (10, 14 and 18% w.b).The mill productivity is determined by dividing the product mass by time; Mg/h. The specific energy consumption: Electrical power consumption was estimated from the measured electric current and voltage values

iron, low power consumption, easy maintenance, wide range output, quiet operation. The basic features of Bowl Mill (Puveriser) supplied by BHEL are: Medium speed range of 40 to 60 rpm. Motor speed range of 600 to 1000 rpm. Speed reduction by two method :

is equipped with three 10 E medium-speed coal mills imported from the U.K. In normal conditions, two of the three coal mills will be in service and the other is for standby. The coal consumption of the boiler is about 60 t/h under full load. The boiler is equipped with two blowers, two primary air fans and

Major developments in the dense medium technology include: (Wills, 1988; Hillman, 2003) • 1858 – Bessemer (UK): First dense medium process patent to remove coal impurities by 'immersion in a tank or bath containing a fluid, the specific gravity of which is greater than the pure coal and less than the substance to be separated there from';
