It is commonly used for wear resistant surface. It is used for shot blasting nozzles, rolling mill rolls, crushers, pulverizers and ball mill liners. By chilling grey or ductile iron on the outside and letting it cool slowly inside, it is possible to produce parts with a hard surface of white cast iron with a ductile core (chilled cast).

reasonable liberation of the mineral of interest, from the host rock. The output diameter of the products to be send to the ball mill have to be less than 12mm and they must have the right shape for the ball mill to operate at optimum conditions. Preferably a diameter of 6mm is perfect and will result in the ball mill operating at maximum capacity.
