  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    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

  • Ball mill Wikipedia

    A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

  • Grinding Media Growth Steel

    Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.

  • Optimum choice of the make-up ball sizes for maximum

    Sep 01, 2013· That is, for an n b set of media size classes, the average value is a linear weighted sum (10) S i ¯ = ∑ k = 1 n b m k S i, k where m k is the weight fraction of the media of size k, and S i,k is the specific rate of breakage of size i material by size k media. These equations can be applied for a known mixture of balls in the mill.
