Mineral Processing Equipment : Dry ball mill rpm calculation - A type of mining equipment that can trigger the development and change of the beneficiation technology industry. The main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
Calculations: 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.
