Abstract
This article presents the results of applying a media selection methodology based on a population balance model to a ceramic ball mill; the experimental data were obtained through the marked ball test in a white-cement grinding pilot plant. Three types of balls from different suppliers (I, II and III) were used in order to study the wear occurring in each type of ball. Tests were carried out for 576h and the law of wear for all three types of balls was found to be zero order. These results were introduced into the model to obtain the ball charge of the mill at steady state and the alumina consumption by wear.
