Evaluation of the key grinding parameters by a statistical approach

• Four important grinding parameters, charge volume, feed rate, mill speed and the degree of classification, were studied. A continuous laboratory ball mill was used. The effects of these parameters on product size, energy consumption and grindability were analyzed by a statistical approach. The results obtained demonstrated that the energy consumption is determined not only by the given product size, but also to a great extent by the operating conditions. The influence of classification in a closed grinding circuit was also examined and it is shown that an efficient classification may improve the grinding process considerably. A sulfide ore containing sphalerite, chalcopyrite and galena was used.
