identification of the grinding mechanisms and their origin

2009-10-1 · The objective of the work was to determine the grinding mechanisms in a stirred ball mill by using population balances. The main grinding mechanisms are cleavage and some fracture for coarse particles (15 μ m), cleavage and abrasion for intermediate particles (0.8 μ m) and cleavage for fine particles (relative size smaller than 0.15 μ m). The results of the studies are in line with the

grinding mechanism of centrifugal mills — a simulation

1996-3-1 · A collision of the wall of the mill body against one of the grinding body (e.g. steel ball) triggers a series of events: 1. change in the motion of the ball normal to the direction of the surface of impact 2. change in the motion of the ball tangential to the direction of the surface of impact 3. change in Vie rotational motion of the ball 4. possible slip of the ball against the wall In this context we assume the mass of the mill body by far larger than that of the ball

ultra-fine grinding mechanism of inorganic powders in a

In the previous paper, a series of wet grinding experiments using inorganic powders by a stirred ball mill were performed. The grinding consumption power was measured, and the grinding rate constant, K, in the grinding kinetics equation was examined, based on a grinding kinetics analysis of experimental specific surface area with particle size distribution of ground products obtained under various grinding
