[citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. 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.
Rod mills, how they function - Mine Engineer.Com Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it .
Rod Mill The grinding media in a Rod mill are long rods of particular material which grind the ore by tumbling within the mill. The grinding action is by line contact between the long rods. There is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. .

Ball mills are commonly used in the manufacturing of cement and finer grinding stages of mineral processing. Typical type of fine grinder is the ball mill.
The plans show stainless steel grinding rods for this size of mill may be a graduated charge from 25 to 10 mm diameter (1 inch to 1/2 inch) but variations in size are not essential. Some mineral processing laboratories use a 30 cm diameter x 61 cm long (12 inch x 24 inch) rod mill with 30 and 45 mm rods (1 1/4 inch and 1 3/4 inch).
The design characteristics of industrial rod mills are similar to ball mills. Most rod mills used in mineral processing are of the overflow discharge type as illustrated in Figure 7.2a. Centre peripheral (Figure 7.2c) and end peripheral discharge mills (Figure 8.1) are also in use.The feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders.
Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded.
