  • Estimation of shear rates inside a ball mill

    1999 9 1 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.
