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.
Bond's formula is a useful tool when comparing | Chegg
Transcribed image text: Bond's formula is a useful tool when comparing crushing applications as well as grinding applications. In crushing energy calculations, a crushability index (impact work index) as determined by laboratory tests is used. Now consider a certain material being crushed in two different size ranges, a coarse crushing range and a fine crushing range, for the same …
