Critical rotation speed for ball-milling - ScienceDirect

View More

Aug 03, 1999 Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter

Dec 01, 2013 In Fig. 3, as anticipated, at a given ball size, a higher rotation speed (rpm) yields a finer average particle size due to the higher number of rotations within a given period of milling time (12 h). Interestingly, at each rotation speed, there exists an optimal ball size at which the most reduced average particle size is achieved among other investigated ball sizes

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

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. 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
