Ball Mill Charging System - 911metallurgist. Mill ball charging systems have undergone little change during the past two decades. Most operations utilize a locomotiveball car combination to load and haul charges from the ball storage bin to the mill charging boxes or, alternatively, transport charges to the charging boxes by means of a ball bucket handled by bridge crane.

A standard ball mill is 305 mm in internal diameter and 305 mm in 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 revmin. The process is continued until the net mass of undersize produced by revolution becomes a constant G b.p in the above ...
