  • The Third Theory Of Comminution OneMine

    Crushing and grinding are concerned both with surface and volume; the absorption of evenly applied stresses is proportional to the volume concerned, but breakage starts with a crack tip, usually on the surface, and the concentration of stresses on the surface motivates the formation of the crack tips The evaluation of grinding results in terms of surface tons per kwhr, based01/11/2016· The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test Its value constitutes ore characteristic and is used for industrial comminution plants designing Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is[PDF] A quick method for Bond work index approximate value
