Lower mill outlet temperature of 5055 deg C needs to be maintained for such coals as compared to 75 90 deg C temperature for indigenous coal. Thus, when firing blended coal, having a component of high Volatile Matter, mill inlet temperature has to be maintained carefully, to ensure drying of coal while taking care to avoid mill fire. d.
Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow takeup rates and frequent plant shutdowns (Rees Fan, 2003).In typical coal fired power plants, there are 48 coal mills ...

Coal is currently beneficiated predominantly in wet condition. The conventional methods for processing of coarse coal like heavy media bath, jigging etc. utilizes water. In the near future, coal resource and water resource is going to have a reverse distribution thus posing several hurdles to wet beneficiation technologies in coal cleaning.
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 ...
