The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wear-resistant alloys for liners and grinding media in mineral grinding environments.
selecting grinding media size, denisty of grinding media, and mill speed to approach an optimum stress intensity and maximize the stress number. Due to Kwade´s investigations and modelling of grinding and dispersing with stirred media mills, the following milling tests with calcium carbonate and different grinding media
to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
The ball mill, liners and grinding media employed were made from stainless steel. This material of construction is superior over all else because of its durability and resistance to wear and tear. It is due to these reasons that contamination of the material was ruled out.
Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding media and mill lining, and in the separator, with the improvement of classification process. Detailed description of the use of grinding aids in cement industry is reported elsewhere [7].
