    2018-12-4 · The mill grinding rate through the size of interest (150 µm, 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, including

  • Particle Size Distribution of Grinding Mill Products

    2019-4-27 · The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected. As the load exceeds 1980 gm it has no influence on size reduction. The relationship between size reduction and input for optimum grinding in the ball mill
