Tactics for Optimizing Crusher and Mill Efficiency: A Guide …
Here are several tactics that you can use: Choose the correct type of grinding media: Grinding media can significantly impact mill efficiency. Grinding media come in various shapes, sizes, and materials, each with advantages and disadvantages. For example, ceramic grinding media are wear-resistant.
Effect of RPM Rod Mill Speeds
The former required more power than the latter when loaded with the same volume of media, and accordingly did more grinding. At 60 percent speed the 1.52-inch rods gave a capacity of 31.4 surface tons per hour, whereas the best capacity in the ball mill at the same speed (table 13) was 30.3 surface tons per hour.

The process input variables in the figure are: u 1 − mill feed water flow rate, u 2 − fresh ore feed rate, u 3 − mill critical speed fraction, u 4 − sump dilution water .
Rod Mills
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 (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
Ball & Rod Mill Density
Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.
Rod Mill Grinding
In the ball mill, the holdup is generally lower than that in the rod mill at corresponding feed rates. As is clear from Figure 8, the maximum feed rate to the ball mill is much less than that for the rod mill. The increase of holdup with increasing feed rate probably results from the resistance offered by the grinding media (balls or rods) to ...
