## critical speed of of ball mill

calculate critical speed of ball millformula critical speed ball mill. formula to calculate critical speed in ball mill. The feed rate (speed at which the machine head moves in XYZ space) and the speed rate (number of revolutions per minute the cutting tool revolves around its axis) need to be proportional to each other, so as to have the machine cut out suitably sized chips.Ball mill - WikipediaA ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.Ball Mill Operating Speed - Mechanical Operations .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. ...
