EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
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).

Mechanical Crushing and Grinding. Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Rod Mills. For fine grinding, rod mills are also used, in which the rods are 40–80 mm in diameter and play a part in the grinding media. In such mills, the contacts between grinding rods and material occur along a line, not at separate points as in ball …

Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into …
This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications.
