Bond Work Index Procedure and Method
Cleaning and Storing ofBall Mill Chargeafter theBond Work Index Procedureis done: Add about 500 g of silica sand into themillcontaining theball charge. Seal themill. Rotate for 20 revolutions to clean. Empty themill chargeand sand into theballtry once grinding is complete. Clean out themillusing a brush. Put the lid on themill.

Bond Work Index - an overview | ScienceDirect Topics
Ball mill designrequires aBond work index, BWi, forball millsat the correct passing size;SAG mill designrequires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
