number of revolution a ball mill makes

A standard ball mill is305 mmin internal diameter and305 mmin internal length charged with 285 balls, as tabulated in Table 2.1. The lowest limit of the total mass of balls is 19.5 Kg. The mill is rotated at 70 rev/min. The process is continued until the net mass of undersize produced by revolution becomes a constant G b.p in the above equation.
