Rod Mills are similar with the Ball Mills xcept they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm ...

As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%. It has been found that as grinding rods wear a 4″ or 4½" rod will generally break up at about 1½" diameter. The smaller diameter new rods do not break up as easily and ...

The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.

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).
