A comprehensive review of stirred mills was published recently by Gao and Weller (1993). While the energetics and kinetics of grinding in rotary mills in general, and ball mills in particular, have been analysed and modelled in great detail (Prasher, 1987), only a limited amount of research pertaining to stirred mills has appeared in the ...

Abstract The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM. This study focused …

Introduction Stirred ball mills feature a stationary mill chamber and an axially mounted stirrer fitted with a number of pins, discs or paddles. The operational peripheral stirrer speed of such a mill is normally in a range of 3 to 12 m/s. By using a high stirrer speed and grinding; media as small as 0.5 mm, stirred ball mills are capable of ...

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 ...
