AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator
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.

different types of rod mill
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 14 to 16 Rod mills accept feed up to about 50 mm (2 in) and produce a product in the size range of

BOOK 2, CHAPTER 17: Regeneration circuits  Hydraulics
A double rodend cylinder costs more than a cylinder with a single oversize rod; the extra rod needs space in which to move; and the second rod seal is another potential leakage source. To eliminate these objections, use the fulltime regeneration circuit shown in Figures 176 and 178. Extension and retraction speed (as well as thrust) is the same, without the extra rod and its problems.

Rod Mill  an overview  ScienceDirect Topics
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.

Grinding control strategy on the conventional milling
Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill.

Closed Circuit Grinding VS Open Circuit Grinding
The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be adapted for fine grinding by substituting a bowl classifier for one of the straight type so as to
