Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.What it is the optimun speed for a ball mill,,I have done a ball mill , recenly finished , but the motor has too rpms , is too fast for use in a ball mill (the pvc cylinder that i use , left of the shafts). With the motor i will use a 40 mm pulley , because i have a 50 mm driven pulley, in one of my two shafts.

## Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and 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.Ball Mill Operating Speed - Mechanical Operations Solved,,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.why critical speed of ball mill is less than one,Jul 01, 2017 · why critical speed of ball mill is less than one; why critical speed of ball mill is less than one. why critical speed of ball mill is less than one; CK6136A economic lathe cnc turning machine cnc horizontal . 4.
