When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the opening in microns of the sieve size tested, then ball mill work index Wi is calculated from the
Learn More1 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
Learn MoreTherefore, the primary standard for choosing steel balls is to have the high-productivity of ball mill and the low-cost of ore grinding medium. About the influence of steel ball hardness, generally speaking, with the increase of hardness, as long as the steel ball isn’t broken, the unit consumption of steel ball will decline, at the same time

Learn MoreThe Hardgrove index is determined using the ASTM method D 409–71. It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured ( w grams) and the index is defined as I = 13 + 6.93 w
