Choose Right Speed To Improve Ball Mill Grinding
The actual mills fluctuated around 76%. in the current production, when the rotation speed of the ball mill is less than 76% of the critical rotation speed, it is called low-speed grinding; when the rotation speed is higher than the critical rotation speed of 88%, it is called high-speed grinding; speed.The critical speed of ball mill is given by, where r = radius of ball mill; r = radius of ball. for r = 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.
