Rod Mill Design & Power Draw
— The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
Rod Mill Liners
— The Ball mills are much like the Rod mills except that they use balls as their grinding media. The size of these balls may range from three quarters of an inch to over five inches in diameter.
