To measure grindability, Bond developed 'Bond's 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. Other index known as 'Hardgrove Index is also used to scale grindability of materials, particularly coal.
