The fractal crushing of granular materials - ScienceDirect

1996-12-1  Crushing of granular materials 2095 suggests that if each of the particles is now to have the same probability of splitting, then (dV(uja,r \d^ (4-2)- (dl2\2 Or/ao)"- ^oJ (3-2)- (49) i.e. a = 1. If a 2, then clearly the larger particles have a greater probability of splitting, and this will tend to scavenge the larger particles out of the ...
