Comparison of grinding media—Cylpebs versus balls

a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power. 3. Laboratory tests As the objective of this study was to predict the grind-ing performance of Cylpebs in a full-scale ball mill, a model-based procedure for scale-up of ball mill wasOptimization of mill performance by using - SciELO,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.A discussion on the measurement of grinding media wear,,Laboratory mill tests can be an alternative to assess the wear of grinding media, as they can reproduce, at least partially, the conditions of an industrial ball mill. Moreover, they are less expensive and less time-consuming than the tests performed at industrial mills.
