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. This manner of conducting the tests gave about the same amount of sub-sieve size in each ...

reason for effect of mill speed on grinding pdf
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
Effect of ball mill grinding parameters of hydrated …
Highlights Operational grinding parameters have marginal effect on fineness of particle. Real surface area enhancement did not occur on the external surfaces, but in the inner surfaces due to lime hydration process conditions. The ball mill load and speed are the most important parameters rather than material charged volume. The undersize percentages of 297, 53 and 10 μm are quality control ...
