    Grindability and Power Consumption.Among various theories of comminution, most commonly accepted which is relevant to ball tube mills is Bonds theory, which states that power input in comminution process is proportional to the surface generated in the process and the grindability of the material. To measure grindability, Bond developed Bonds Work Index BWI, a test mill and a testing procedure for WI. With the help of this we can work out power required to grind a material from a given feed size to a product of given fineness.
