Bond Work Indexan overview ScienceDirect Topics

Ball mill design requires a Bond work index BWi for ball mills at the correct passing size SAG mill design requires 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 ).

rod mill grindability tests. As discussed earlier in this paper it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such primary ball mills should be designed with the rod mill work index and single-stage ball mills should be with both the rod mill and ball mill indices.

How it Works Crushers Grinding Mills and Pulverizers

Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles and ore material. Pebble mills may be used when metal balls must be avoided. Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to
