Stage grinding which is by repeated passes followed by removal of the finished material, is the best means of obtaining selective grinding. These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding. Ball Mills = Non-Selective

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. Dry grinding requires more energy than wet grinding. A stage of breakage is defined as the interval taken to eliminate the largest sieve fraction from the mill feed or the feed to
The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media.

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Ball mill, as the key grinding equipment of the materials, is widely used for mineral grinding such as cement, lime, quartz, slag, silica, iron ore, copper ore, gold ore, bauxite, calcite, barite, gypsum and other minerals in mining, quarry, chemical, cement and other industries. Ball mill is the necessary equipment in ore beneficiation plant.

Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing. 2. In the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage, rod
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
