In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Live ChatThe complete ball mill is bedded on a steel or concrete frame designed to rest on a defined number of load cells. The load cells are integrated into a control unit and determine the total weight of mill, grinding media and product. The addition of feed can be controlled with such precision that the mill always operates at optimum load.

Live ChatRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and
