  • AMIT 135: Lesson 7 Ball Mills Circuits Mining Mill

    Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dV = 0.40 KF dB = ball size (cm) F = feed size (cm)

    Re: How Can I calculate new ball size and weight desing for ball mill. Hi, We have a similar mill. Pregrinding with hammer crusher and mono chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.

  • Calculate and Select Ball Mill Ball Size for Optimum

    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.

  • Ball Mill: Operating principles, components, Uses

    A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.

  • Ball Mill an overview ScienceDirect Topics

    The feed to ball mills (dry basis) is typically 75 vol. % ore and 25% steel. The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones. The cyclones send correct size material on to flotation and direct oversize material back to the ball mill for further grinding.

  • Feed Size VS Ball Size Grinding Classification

    A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi self locking taper. One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill.
