download citation on researchgate critical rotation speed for ball milling critical rotation speed of dry ball mill was studied by experiments and by numerical simulation using discrete element method (dem).
the critical speed of ball mill is given by, where r = radius of ball mill; r = radius of ball. for r = 1000 mm and r = 50 mm, n c = 30.7 rpm. 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
