A hardness and structure gradient is usually viewed as undesirable because of faster wear of softer constituents. But the hardness gradient can be exploited to manipulate the ball size distribution of the ball charge to produce better mill grinding capacity and lower ball consumption than is obtained using a ball with harder interior metal.
