Optimization of Solids Concentration in Iron Ore Ball Milling

2019年6月18日 Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to

Calculation of Top Grinding Media Size -Ball Sizing - 911

2015年10月14日 A ball size-correction method can be used along with the specific selection function scale-up method to determine the best ball size. To do this, a set of “ball size tests” are performed in a batch mill from which the specific selection function dependence on ball size can be determined. Then, the mill capacities used to produce
