    Mar 14, 2015 Ball mills are machines which are used to reduce the granular size of powdered chemicals and to efficiently mix multiple chemicals together. This is an important requirement for good pyrotechnic compounds, the finer the grain of a pyrotechnic compound and how well it has been mixed with other constituents determines how efficiently the compound

    The ball diameter is smaller than that of horizontal ball mill. Glass balls or ceramic balls (such as vertical ceramic ball mill ) can also be used according to the grinding requirements. For the case where the finished product has special purity, the grinding medium can also be the raw material with a larger size (such as SAG mill )

    Calculate and Select Ball Mill Ball Size for Optimum Grinding

    Aug 02, 2013 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

    Sep 01, 2020 Size segregation of granular mixtures is one of the common types of segregation in a rotating drum. This phenomenon occurs in process equipment such as mixers, ball-mills and rotary-kilns. Here, we studied the segregation of bidisperse spherical glass-beads with size ratio ranging from 0.1 to 0.9 in a rotating drum by experiment and DEM modelling
