justfy the operation of a rod mill in an open circuit. Most rod mill applications involve wet grinding where materials are reduced in size from crusher product size to a size suitable for ball mill feed. To avoid breakage or tangling of rods the L/D ratio of rod mills is kept within the limits of 1.4 1 to 1.6 1.
Jan 01, 2016· For rod mill operation only. Feed prepared by open circuit crushing: Use a factor of 1.4: Feed prepared by closed circuit crushing: Use a factor of 1.2: Factors F 3, F 4 and F 6 have also to be applied: Use F 3, F 4 and F 6: b. For rod mills in a rod mill–ball mill operation. Rod mill feed from open circuit crushing: Use a factor of 1.2
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...
The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained by restricting ore feed size to 3/4".

Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. 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.
