Jun 01, 2009 It is worth analyzing the mass balance equation for the case where the magnitude of the lowest impact energy in the mill is higher than the fracture energy of the toughest particle in the charge. This condition is approached by a mill that is fed with particles contained in a comparatively fine size range when compared to the ball size.

is the specific rate of breakage, M is the mass of material in the mill, and m i is the fraction of the mill contents in size class i. The formulation of PBM for grinding has been developed by different authors e.g., Austin et al., 1984. In brief, a mass balance for class
A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature feed and discharge streams, mill power draw and the mass flow rate in the feed stream.
