• ### Critical Speed Of Ball Mill Wikipedia

Milling Equipment prove critical speed of a ball mill A class of machinery and equipment that can be used to meet the production requirements of coarse grinding, fine grinding and super fine grinding in the field of industrial grinding.The finished product can be controlled freely from 0 to 3000 mesh.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.
