How Slurry Transport inside a Tumbling Grinding Mills
May 24, 2018· The transport of slurry through the ballbed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill. When balls of different sizes are present in the mill, then there is a tendency for the balls to move at different speeds along the axial direction. Ideally, balls would not move in the axial direction

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.
