The residence time in ball mills is long enough that all particles get consistent treatment, which also provides a narrow particle size distribution. Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ” to 1.5”.The mill grinding rate through the size of interest (150 m, the circuit target P80) calculated from the plant survey data using the functional performance equation was 0.0568 t kWh. The ‘energy specific cumulative grinding rates’ for the survey calculated from ball mill feed and discharge size distributions.

With the bimodal size distribution ball. Additionally, [15] examined the efficiency of a laboratory mill where alumina powder was milled by zirconia beads in an aqueous medium and found that for a specific mill’s rotation speed there is an optimal size ball that minimizes the alumina particle size.Cement mill Wikipedia. However, particle size distribution is again a problem, and roll presses are now increasingly popular as a pre-grind process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40 compared with a standard ball mill system.
