## (PDF) SIZE REDUCTION BY GRINDING METHODS

grinding material at smaller particle sizes, and can be used after ball mills in a grin ding process Like dolomite, marble, silica sand, limestone, bento nite, lime,

The reduction of size of dolomite particles is expressed by equations 12 and 13: A comparison of the size reduction by impact and ball mill grinding is shown in figure 2 The ball mill experiments show the size reduction versus energy input for 7 series of experiments in which the weight of dolomite was 660, 1320, 1980, 2640, 3300, 3960, and

Small grit sizes produce better finishes, larger grit sizes permit larger material removal rates Also, harder materials need smaller grain sizes to cut effectively, while softer materials require larger grit size Grain sizes used in grinding changes between 8250, while 8 is very coarse, but 250 is very fine 15
