2019-8-30  1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

##### How to Calculate the Coal Quantity Used in a Power Plant ...

2009-10-15  Coal trader’s web sites give base prices in the international market. We take a coal price of around 65 \$ / Ton. The cost of coal consumed by 100 MW power plant is (53.8 x 65) 3497 \$ /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) 3.5 cents per unit.

##### Exploring ball size distribution in coal grinding mills ...

2014-5-1  Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%.
