grinding - ball mills. the rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. the larger the diameter, the slower the rotation. if the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

in ball mill, pulley and gear reduction mechanism is the key factors for cylinder rotating speed which is generally fixed. this speed will directly affect the grinding process. ores and grinding media movement conditions will vary with the rotating speed. in grinding process, the grinding media and ores will go upward along the cylinder inner wall.
important consideration for a ball end mill is feed rate. along with that decreased surface speed toward the center goes increased chip load. start your feed at half what you would use for a similar strht cutter in the same material, at the same rpm.

ball mill speed? - posted in newbie questions: hi guys, i am a veteran of class c fireworks but a stone cold 'green' newbie to the hobby of making fireworks. i am in the process of building a ball mill. i have all the components needed including the media and have the cabinet built with 2 axles, but can not for the life of me figure out what the proper rpm of my jar should be.
this means that when the mill is running at the proper speed for the ball charge, then the charge is passing through 1.444 cycles per revolution, and each ball in the charge strikes, on the average, 1.444 blows per revolution.
