01/08/2011 · The breakage of particles depends on the speed of rotation. Working with a m diameter and m long mill, NapierMunn et al. [4] observed that the breakage rate for the finer size fractions of ore (say mm) at lower speeds (, 55% of the critical speed) was higher than that observed at higher speeds (, 70% of the critical speed ...

23/12/2018 · Critical Speed If the peripheral speed of the mill is very high it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill and that point is called the "Critical Speed" (n c).This phenomenon is called centrifuging. Ball mills usually operate at 65 to 75 of the critical speed.

11/03/2014 · The grinding medium moves in different ways depending on the rotational speed of the mill. Low speeds create a cascade motion in which the balls merely roll around. As the speed increases, the balls are lifted and fall onto the milled material ("aracting" motion). Above the socalled critical speed, the balls are held against the drum ...
