• Ball Mill Critical Speed Mineral Processing Metallurgy

    Ball Mill Critical Speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range. Pebble mills are usually run at speeds between 75 and 85 percent of critical speed.

  • What it is the optimun speed for a ball mill

    Oct 19, 2006 路 Congratulations on your ball mill! Youll want to further reduce your motor speed by 3:1 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media wont do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.

  • Mill Speed Critical Speed Paul O. Abbe

    In most cases, the ideal mill speed will have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way. The ideal mill speed is usually somewhere between 55% to 75% of critical speed. Critical Mill Speed. Critical Speed (left) is the speed at which the outer layer of media centrifuges against the wall. Second Critical Speed (middle) is the speed at which.

  • critical speed range ball mill

    The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application. Get Price.
