The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.

acidresistant mills for grinding in raffinate or with acidforming feed, as well as special feed and discharge arrangements and special bearing arrangements. Outotec SAG and ball mill Outotec highperformance grinding mills use advanced simulation tools for the best possible process efficiency, mechanical reliability, and maintainability.

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.

• characteristics of the grinding media (mass, density, ball size distribution); • speed of rotation of the mill; • slurry density in case of wet grinding operation. Quantitative estimations of these parameters can be found in [4, 5, 23]. An important characteristic of an industrial ball mill is its production capacity

grind media distribution calculation for ball mills . Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to continuously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
