Get priceprobability of fiber breakage is directly proportional to fiber length (Meyer et al. term this the selection function), and (2) in an arbitrary time interval, a fiber breaks, if at all, only at one point into two segments. Both assumptions seem quite restrictive, especially the first one, in

Get priceThe "selection function"; referred to as the probability of particle selection was associated with the geometry of the comminution environment and other factors, such as stressing velocity. The classification function was linked to the geometry and the spatial distribution of fragments during breakage.

Get priceIn this model the breakage rate (or selection function, S i) can be interpreted as a ﬁrst order rate constant and B ij is the breakage distribution function describing the mass fraction in the ith size range from breakage of particles in the jth range. The breakage rate is usually assumed to be a constant
