Exploring abrasive wear, friction and ore breakage.

The abrasion wheel test used to determine the contribution of abrasive wear and friction to the total wear of steel grinding media provides an opportunity to study ore breakage as well. Tests were carried out using standard Ottawa foundry sand. It is shown that the abrasive wheel test produces fine particles, that it can be used to determine the operating work index, the locked cycle work index and the t10 function for a given ore, that the amount of prepared ore to determine the breakage parameters varies with the test method used, that in conjunction with these tests steel media abrasive wear and friction can be determined, and that all test results indicate a relationship between steel wear, friction, and abrasive ore breakage. Implications of the work and further directions it may take are considered.
