High Energy Ball Mill. Ball Mill is a grinder that blends or grinds materials for various applications. Impact force enables size reduction in feed material. The cylindrical shell rotates around its horizontal axis. The main element enabling grinding is the hard and small balls in the ball mill. These balls are usually made of steel.
The critical speed of ball mill is given by, n c = 1 2 π g R − r. 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 ...
