ball mill parameter selection amp calculation power aug 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 more balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will exploring ball size distribution in coal grinding mills researchgate. abstract tube mills use steel balls as grinding media. new balls periodically to maintain a steady balanced ball charge in the mill. of the calculation of the size distribution of the equilibrium mixture of balls in a ball mill is developed.ball mill working principle and calculation. ball mill working principle and calculationworking principle operationthe apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a ball mill has a working diameter of inside the liners and has per cent
