recognised basis for design of certain types of mill One of them is the Hardgrove index associated mainly with vertical spindle mills and the other is Bond's grindability associated with tumbling mills (PrasherJ987) Bond's grindability can be empirically related to the energy required for comminution and thus is useful for the design and selection of crushing and grinding equipment (Deniz

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill scale-up
