    Feb 01, 2011· Research highlights The in-mill slurry RTD has been sufficiently described by a model comprising one large and two small perfect mixers in series with a plug-flow component. The mean residence time correlated linearly with slurry concentration and ball load volume but inversely with feed flow rate. The results are indicative of a positive effect of RTD on the prediction accuracy of mill

  • 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
