    Calculate and Select Ball Mill Ball Size for Optimum Grinding

    Aug 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

    Oct 20, 2016 Oct 20, 2016 Approximate ball loads can be estimated by assuming 300 lb. per cu. ft. of ball volume and a total load equivalent to 40 to 45 per cent of the mill volume. Rod loads average about 40 per cent of mill volume, and a figure of 400 to 425 lb. per cu. ft. of rod volume should be taken

    May 08, 2020 May 08, 2020 Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%

    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

    The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a
