Get QuoteOct 20, 2016· Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding. A much higher grinding capacity is obtained in tube mills by using steel media instead of pebbles, but in making such a conversion serious consideration must be given to the ability of the steel shell to withstand the
Get QuoteAug 02, 2013· 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.
Get QuoteOct 01, 2020· Grinding media directly affects the load behavior and, consequently, the performance of industrial mills in terms of product size, energy consumption, and grinding costs. ( Lameck et al., 2006 ) examined the impacts of different media shapes on the load behavior and power draw based on a function of mill filling and speed.
