Your company has bought a ball mill and now you would like to know what performance to expect from it? You are going to buy an expensive ball mill and now would like to know what profitability to expect from it? You need to process (grind) a certain mineral and would like to choose the most efficient.
To calculate the needed grinding work against the grain size changing three half-empirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be.

Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades. Simulation software and power-based equation methodologies have been established for designing AG/SAG.
is the mill speed in rev/min. N. is the number of rollers in the tandem. L. is the length of the roll in metres. D. is the mean diameter of the rollers in metres. f. is the fibre percent cane. The problem with M. Hugot's equation is that is a function of the square of the mill speed, which means mathematically that the mill capacity will.
