Enables safe relining of smaller SAG and ball mills unsuitable for traditional reline machines. Easier navigation of small mill decks enabled by four-wheel drive and tight steering angle.
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.
Ball Media. Generally, steel grinding balls are used with steel mills, ceramic balls are used with porcelain or ceramic lined mills and steel, ceramic, or other high density media is used with elastomer lined mills. Porcelain balls have a SG of 2.3 and have a average weight/volume of 12.8 pounds per gallon.
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.

type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …

Rod and Ball Mills not so much however as their size reduction actions are hidden in the tube (mill). As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its 3.5" x 16' rods at one end while the smaller particles migrate towards the discharge ...
The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. …
3.2 Rod Mill Design A different approach is taken with the rod mill design where equations by Bond and Rowling are used to calculate the mill power draw. The Morgärdshammar equation and the IMM equations are shown for comparison. The method of use is similar to the AM section 3.3 Ball Mill Design
Comparison between Rod Mill and Ball Mill. 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.
invention in France which involved a tube mill with a charge of steel balls or flint pebbles for fine grinding of sand or cement. F.L.Smidth acquired the rights to his patent and started selling an improved version of this mill all over the world. For the cement industry the ball mill was really an epoch-making breakthrough as for almost
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).
