    Reduction Ratio 15 1 to 20 1 Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter.
