##### Sizing a Regrind Mill for Fine Grinding Grinding

Whether it is practical and/or worthwhile to run a Bond Ball Mill Work Index test at 500 mesh (25 micron)? Are there calculation alternatives? This would be for sizing of fine grinding or regrind 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.
