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.
