Ball mill production performance. the mass fraction is 45. -65. therefore, the lattice type ball mill is often used as a rough grinding device, or a grinding operation.
But the mill is operated at a speed of 15 rpm. therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. if 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same, speed of ball mill = [0.4886/ (2 p)] x [9.812/ (1 - 0.025)].
Critical speed of ball mill . for a ball mill, it does not have a constant critical speed, because of the centrifugalization of the steel balls is different according to different resistance and friction between ball loads.but the ball speed of centrifugalization is constant. when the critical speed of the ball mill also has a constant value, such as the grinding medium fill rate, liner type.
