WhatsApp: +86 18838072829The 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,, 40,, and mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling operation, the feed ...
WhatsApp: +86 18838072829To solve the problem involved in the grinding of cassiteritepolymetallic sulfide ore in which fine grinding causes the cassiterite to be overground or coarse grinding leads to inadequate liberation of sulfide minerals, the influences of the ball grinding medium on the size distribution of the grinding product were investigated. Two types of ball filling patterns, namely, singlesized and ...
WhatsApp: +86 18838072829If, however, a tube mill is divided into a number of compartments and the mean ball size of the grinding media decreases in each succeeding compartment; then the optimum ratio between ball size and particle size is more nearly maintained, and a better overall performance of the mill is achieved; this giving rise to the compartment mill shown in ...
