Breakage is not so apt to occur during shipment, and any size ball can be charged into a mill equipped with molychrome liners. Manganese liners for Ball-Rod Mills are the world famous AMSCO Brand, and are the best obtainable. The first cost is the highest, but in most cases the cost per ton of ore ground is the lowest.

Second, the basic principle of energy saving of ball mill The material in the ball mill, the steel ball and the liner collide with each other to produce noise, and the noise varies with the change of the material quantity in the ball mill.When the material is less, the collision probability of steel ball and liner is large, the energy is large, and the noise is large.
