Bond Ball Mill Work Index Test (BBMWI) is a standard test for determining the Ball Mill Work Index of a sample of ore. The BBMWI 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 for material under ball mill grinding conditions.
