1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

When the test ball mill is run in open circuit the design feed rate is tonnes/hour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of, and tonnes/hour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.
