Behavior of Grinding Functions

The energy laws of Bond, Kick, and Rittinger relate to grinding from some average feed size to some product size but do not take into account the behavior of different sizes of particles in the mill. Computer simulation, based on population-balance models [Bass, Z. Angew. Math. Phys., 5(4), 283 (1954)], traces the breakage of each size of particle as a function of grinding time. Furthermore, the simu-... [Pg.1836]

It may be easier to fit the parameters by forcing them to follow specified functional forms. In earhest attempts it was assumed that the forms should be normahzable (have the same shape whatever the size being broken). With complex ores containing minerals of different friability, the grinding functions S and B exhibit complex behavior near the grain size (Choi et al., Paiiiculate and Multiphase Processes Conference Proceedings, 1, 903-916.) B is not normalizable with respecl to feed size and S does not follow a simple power law. [Pg.1839]
