increase of mill speed and optimum speed was not reached in the range of chosen mill speed fractions. Again the rate of breakage was plotted as a function of particle size, the optimum size was mm when milling at 30% critical speed. As for 20% and 30% optimum size was not reached.

Jadi putaran kritis ball mill model 1200 x 3000 adalah 38,6 rpm. Agar material yang ada dalam ball mill tidak menempel pada dinding mill, maka putaran mill harus kurang dari 38,6 rpm. Secara praktis, besarnya nilai kecepatan kritis yang digunakan untuk penggerusan pada ball mill adalah antara 50 90 persen dari Nc.

ballonshell impacts just above the charge toe, owing to the risk of ballonliner damage and excessive metal flow. In fixedspeed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.
