Media to media contact for rods mills is linear rather than point to point as with balls and are much heavier The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded This leads to a narrower size distribution and significantly less slime compared to ball mills

In this article alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated Silica ore was used as the test material The experimental parameters that were kept constant in this investigation was the

The two grinding media have different surface area bulk density and contact mechanisms in grinding action Comparative tests were conducted using the two types of grinding media in a laboratory Bond ball mill at various conditions of equality such as media mass size distribution surface area and input specific energy
