rod mill work index classification - infissibologna.it

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.get price

Rod Mill Feed Size - Grinding & Classification Circuits ...

Rod mills have become niche comminution devices since about 30 years ago. Because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling (a potentially deadly failure for those tasked with rectifying the problem) rod mills have a maximum installed power of about 2.5 MW.

Rod Mills, How Do They Work? - Mine Engineer.Com

Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.
