Here is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load.
Larger grinding media has a smaller grinding surface area, but offers a heavier weight that's generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization.
