Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...

During Survey #1 at the Camco Mine, the ore feed rate to the ball mill circuit was 67 t/h. The circuit feed contained 29.33% of -106 micron (150 mesh) material (fines) and the circuit product contained 78.54% of -106 micron (150 mesh) material. What was the circuit output of fines during the survey?

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.
