    Jul 03, 2017 Effect of RPM Rod Mill Speeds. In a study of rod-mill discharge openings of different sizes, four pairs of tests were made at speeds of 40, 50, 60, and 70 percent of critical. In each pair the discharge openings were 8.0 and 4.5 inches, respectively. The tests were conducted so that the tons per horsepower-hour were nearly the same.

    Grinding mill speed, it should be noted, is not absolute, not a definite rpm, but relative to a quantity called critical speed. The critical speed of a mill is defined as the lowest rpm necessary to centrifuge an infinitely small particle next to the shell lining within the mill. By equation: where CS=Critical speed in rpm. D=Internal diameter ...
