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.
