Rarely is there a relationship between the Bond ball mill work index and the Bond crushing (impact) work index. Two reasons for this are: The size range over which the two tests are valid (the ball mill test feed is about 2 mm, whereas the crushing test feed sizes are between 50 mm and 75 mm).

When making comparisons of the efficiencies of different grinding and crushing machines it is desirable to be able to estimate the work actually done in crushing the ore from a given size of feed to a given size of product, the screen analysis of both feed and product being determined. Messrs. Klug and Taylor, in a paper on this subject, …
