What Is Grinding Media To Ore Material Ratio

Primary Secondary AG Autogenous Grinding
· The media wears through a critical size range, but the range is probably small and the quantity small enough so that the wear rate is fast enough to prevent a buildup. The ratio of media size to ore size in terms of particle diameter is larger than that in intermediate autogenous grinding, and may be as high as 30 to one. No reports indie ...

How it Works: Crushers, Grinding Mills and Pulverizers ...
· Autogenous grinding (AG) and semiautogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semiautogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
· 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.
