  • 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”.

  • How Coarse can Ball Mill Feed be Grinding

    Feeding >15mm to a ball mill this size is not typical much larger ball mills (>21' or 7.0m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 3.5"- 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 50-60mm.

  • Feed Size VS Ball Size Grinding & Classification

    For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) DM function of the feed size xG (80% passing size µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):

  • Ball mills Fruitful

    Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size.

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

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

    However, as a group, they are not entirely satisfactory because the optimum mixture of balls depends on the feed size as well as the product size. Further, the ball size distribution in the mill is not a simple parameter that can be controlled directly, as it depends on the make-up ball charge and wear rate.

  • Effect of Grinding Media on Milling

    Thus, it follows that the expenditure of equal amounts of work produce practically identical products from the same feed, regardless of the density of the grinding media.) When the ball charge is fixed, variation of the quantity of ore in the mill brings about no significant selective grinding between the different sizes of material in the feed.
