The breakage function; What is it really? ScienceDirect
1990-1-1 Abstract. 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 the breakage distribution function can be considered to result from two different breakage processes; shatter and cleavage.

On the breakage function for constructing the fragment
2019-6-1 The breakage function adopted by Brosh et al. (2011) was obtained from impact tests. It is clear that the breakage function estimated from a single particle compression test differs from that derived from an impact test, and the breakage function is also sensitive to the impact velocity (Kalman, Rodnianski, & Haim, 2009; Khanal, Schubert

2020-9-1 1. Introduction. Nowadays, with the increasing depletion of high grade and coarse-grained ores, the trend is towards the extraction of low-grade ores .This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes,which in turn leads to higher energy
