The ball mill grindability test, which is similar to the Bond grindability test, was first introduced by Maxson, Cadena and Bond in 1933 (Maxson et al., 1933). Later, F. Bond developed a new grindability test as the Bond grindability Index as a method in 1956 with both different mill diameter and different material and ball load.

the grindability of the material corresponding to the con-ventional Bond work index experiment. In the experiment, a conventional Bond laboratory mill with "DxL = 305 x305 mm" balls and a rotation speed of 70 min was employed. Bond (1961) employed dry grinding to simulate a closed grinding cycle until a circulating load of 250% was obtained.

Bond's work index is one of the mostly widely used metrics of mineral grindability. In spite of its ubiquity, users are often not aware of the nuances of the work index family: what are its strengths and weaknesses. Moreover, the operating work index frequently gets confused for a specific energy (SEC) consumption in documents such
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 ...
