199581 A sizeenergy model is proposed for simulation of stirred ball milling. The product size distributions below 10 /~m from a stirred ball mill were simulated by the model satisfactorily. The model is simple and has only two parameters. The model was tested under different milling conditions for a stirred ball mill.

13/08/2014 1 Class Exercise – Product Size Distribution A hard ore is ground in a ball mill and the product size distribution is shown as Grind A in the Table. The downstream process was giving problems and was found to be sensitive to large particles. In order to eliminate these problems, the mill is modified with the aim of producing a grind with a smaller average particle size.

Calculate and Select Ball Mill Ball Size for Optimum
201382 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.
