platinum group metals (PGM). The investigation of INCO Clarabelle Mill grinding circuit products shows that, like gold, PGM selectively enrich in some of the grinding products, such as ball mill discharge and cyclone underflow, and they are amenable to gravity separation. The
Rod mills are very similar to ball mills, except 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.
Oct 12, 2017· Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters. Rod Mill-Ball Mill Circuits Diagrams of mill circuits [image: (135-8-2)]
Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems.
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. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit ...
