• Analysis of ball mill grinding operation using mill

    Siddique has presented data on dry grinding of 10/14 mesh limestone in 254, 381 and 762 cm diameter ball mills The mill speed, ball load and particle load values corresponded to: (N: 06; J: 05; U: 10) Balls of four different diameters, 127, 1905, 254 and 381 mm, were used for preparing the ball charge The proportion of balls by
