By subjecting chromite ore samples to repeated forces in a tumbling ball mill media, they would become progressively weaker, and since the retention time is long they would eventually break. These results in higher values of D F indicating the more regular the particle size distribution and the greater proportion of fine particles in ball mill ...

1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite common in the cement industry [2], [4], [5].
