Bond Rod Mill Index JKTech Mill (Grinding) Nature

2019-11-8  A Bond Rod Mill Index Test (BRMWI) is a standard test for determining the Rod Mill Work Index of a sample of ore. The BRMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding consitions.
