• 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.Study on Sumbawa gold ore liberation using rod mill,2017-10-24 · Study on Sumbawa gold ore liberation using rod mill: effect of rod-number and rotational speed on particle size distribution.

  • Size Reduction and Energy Requirement ScienceDirect

    2016-1-1 · For a rod mill–ball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of 1.2 for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less (e.g. from a closed circuit crusher) do not apply a rod mill efficiency factor.AMIT 135: Lesson 6 Grinding Circuit Mining Mill ,The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. 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.
