Calculations: 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

The critical speed for the milling jar is calculated using the equation 1. Critical rotation speed is a function of a ball radius and a mill jar diameter. CS = 265.45 ID-d. Where C.S is critical speed, I.D is the internal diameter of jar and d is the size of balls and speed in revolution per minute (RPM). Usually 55% to 75% of critical speed is
