Design of a crushing system that improves the crushing

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. Currently the ball mill is being fed 12mm diameter products. The shape of the output product is also important.
