Jan 01, 1990· Mosttumbling mill breakage distribution functions described in the literature have been determined from mill charges, andrepresent average conditions. More recent work [26],[27],[28] on the direct breakage of single particles shows that as the energy intensity is raised, the overall product size distribution becomes finer.
[email protected]This paper discusses the breakage function (better called the breakage distribution function) used in the population balance method of analysing size reduction. It is concluded that thebreakage distribution function can be considered to result from two different breakage processes; shatter and cleavage. In size reduction equipment in practice, an individual fracture event usually involves both processes, and …

Get PriceThe distribution function agrees with the following exponential distribution formula as a whole; B(y, y max)={1-e-α(y/y max)}/(1-e-α) Where α is the distribution factor, and a function of the particle size. It is expected that variations of α by the charge condition are effects of secondary fractures.
