Ball mill critical speed calculation the height the ball raised is high now only the calculation formula on critical speed in theory is widely usedmatches 1 how to calculate critical speed of ball mill
The point where the mill becomes a centrifuge is called the critical speed and ball mills usually operate at 65 to 75 of the critical speed ball mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns
Jan 24 2012 critical speed 26545 sqrt jar id in inches media diameter in inches for an 85" id jar with 12" lead media the critical speed is 9382rpm 65 of that is 6098 rpm for a 6" id jar the critical speed is 113rpm 65 of that is 735rpm
Most ball mills operate at approximately 75 critical speed as this is determined to be the optimum speed the true optimum speed depends upon the drum diameter larger drum diameters operate at lower than 75 critical speed whilst smaller drum diameters operate at higher than 75 critical speed
What is critical speed in grinding ball mill critical speed mineral processing metallurgyhe percent of critical speed is the ratio expressed as a percentage of the actual mill speed and the theoretical critical speed of that mill the critical speed of a rotating mill is the rpm at which a grinding medium will begin to centrifuge namely will start rotating with the mill and therefore cease to
