Bond Rod Mill Index Test BRMWI A Bond RMWI test is a standard test for determining the Rod Mill Work Index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 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.
Screw classifiers can be classified into high weir single spiral and double spiral, sinking four kinds of single and double helices grader.
