WEBER, U.  e  LANGLOIS, D.. The effect of grinding media performance on milling and operational behaviour. J. S. Afr. Inst. Min. Metall. [online]. 2010, vol.110, n.3, pp.147-152. ISSN 2411-9717.

The effect of grinding media performance on milling and operational behaviour was demonstrated under different selected conditions of calcium carbonate slurry milling. A variety of grinding media materials and bead sizes, along with two different stirrer tip speeds, were used in the grinding process to generate a particle size reduction of the calcium carbonate (CaCO₃). To determine the optimum milling parameters the collected test data were used to calculate and evaluate specific energy as well as stress intensity under different milling conditions.
