Get PriceCalculation of energy required for grinding in a ball mill int j miner process 25 4146 the bond work index wi as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product
The majority of grinding balls are forged carbon or alloy steels generally they are spherical but other shapes have been used the choice of the top or recharge ball size can be made using empirical equations developed by bond 1958 or azzaroni 1984 or by using special batchgrinding tests interpreted in the content of population balance models lo and herbst 1986 the effect of
A total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to be
Besides particle size reduction ball mills are also widely used for mixing blending and dispersing amorphisation of materials and mechanical alloying 1 49 51
