At what speed will themillhave to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: The critical speed ofball millis given by, where R = radius ofball mill; r = radius ofball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But themillis operated at a speed of 15 rpm.
Mill Critical Speed Determination. The "Critical Speed" for a grindingmillis defined as the rotational speed where centrifugal forces equal gravitational forces at themillshell's inside surface. This is the rotational speed where balls will not fall away from themill'sshell.
Dec 08, 2009· Re:how to estimate the wear rate for Ball mill. Hey;Ballwear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit ofballsurface, the total charge wear can be estimated.
Moreover, according to different materials and discharging methods, there are dryball millsandwet ball millsfor choice. The Working Principle ofBall Mill: This machine is a skeleton patternball millwith horizontal cylindrical turning gear, driven by outer gear and two hoppers.
