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).
