Size Distribution Between A Roll And Cone Mining Mill

Determining the particle size distribution from a ball mill known as the distribution function describes the distribution of fragment sizes obtained after a breakage of particles of size xjThus bj bj bnj are the mass fractions of particles in size classes n after a breakage of particles in size class j the mechanism of breakage is illustrated in by a diagram shown in fig
