The grinding media for a ball mill is usually steel balls sized from about 1 to 10 cm in diameter, and for rod mills about 1 to 10 cm in diameter, with the length being slightly shorter than the length of the rod mill. The grinding circuit product can be made very fine, if necessary, with the majority of material finer than 20 microns (um).

Mill circuit cyclones from Multotec maximise mill efficiency and reduce the energy per ton required.This is achieved via their unique inlet design and, additionally, the cyclone configuration can be altered to accommodate changing operational conditions.. Improved mill capacity by this cyclone, part of Multotec's range of classification cyclones, facilitates increased throughput.

No 1 rod mill/ball mill circuit was operating very effi ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being fi fi ner than 650 μm.

Working Principle of Ball mill: As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.

Rod Mill - an overview | ScienceDirect Topics

The Rod line maximum capacity is 264,000 short tons per year. Molten copper is molded into a bar at a rate less than ½ a mile per hour and exits the mill close to 72 miles per hour. The bar is rolled through 16 stands and is reduced from a 2.5" x 5" rectangle bar to a 5/16" rod (1/200th of its original size).

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.
