Critical speed of ball mill machinery supply Ball mill is the most common used grinding mill for stone powder making plant or mineral ore processing plant. Ball mill critical speed overview

the critical speed, and ball mills usually operate at 65% to 75% of the critical speed. Ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being

Jan 14, 2013· 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 = rpm. For R = 1000 mm .
