Estimation of shear rates inside a ball mill

Grinding slurries are known to be non-Newtonian. For such suspensions, slurry viscosity is not a constant, but is a function of shear rate. This study was aimed at the derivation of an estimate of a typical shear rate range inside a ball mill, in order to determine appropriate values of apparent viscosity for studies of the effects of rheology on grinding.
