    Effect of Grinding Media Size on Ferronickel Slag Ball

    Dec 27, 2021 The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling

    Effects of mixtures of grinding media of different shapes

    Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding

    An increase of over 10% in mill throughput was achieved by removing the ball scats from a single-stage SAG mill. These scats are nonspherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t.
