Estimation of shear rates inside a ball mill

1999-9-1 · The shear rates inside a ball mill were therefore estimated to lie between approximately 13 and 730 s −1. Shear rates in this range should therefore be used to characterise the apparent viscosities of slurries in grinding applications. Values for particular mills and operating conditions can be formulated from the methods presented in this paper.

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.
