It is a wellknown fact that the value of the Bond work index (wi) for a given ore varies along with the grinding size. In this study, a variability bysis is carried out with the Bond standard grindability tests on different critical metal ores (W, Ta), ranging from coarse grinding (rod mills) to fine grinding (ball mills). The relationship between wi and grinding size did not show a clear ...

Ball and Rod Mills. JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

The dominant mechanisms of comminution are very different in the two tests (the crushing test is mostly measuring impact crushing strength of fractures in the rock, whereas the ball mill test is measuring the abrasion strength of the matrix of a rock and the attrition resistance of individual grains within the rock).

A Bond rod mill work index test (BRMWI) is a standard test for determining the rod mill work index of an ore sample [21]. The BRMWI is a measure of the resistance of the material to crushing and grinding in a rod mill and is used to calculate the grinding power needed for a given material parcel regarding rod mill grinding conditions.
