It follows that theaverage throughput velocity is the quantity of flow divided by the area open to flow. From this average velocity the time for a particle to traverse the mill may be computed. This treatment does not, however, indicate whether, for a given rate of flow, the surfaces of the powder mil the ball charge will coincide or not.

Estimation of shear rates inside a ball mill - ScienceDirect
The Reynolds number for a ball moving relative to a slurry with a tangential velocity Ut is (39) Re = U t D b ρ μ. From surveys of the Hellyer ball mill ( Shi, 1994) the apparent viscosity at 200 s −1 is 0.15 Pa·s at the highest slurry density of 2880 kg/m 3, and 0.01 Pa·s at the lowest density of 2180 kg/m 3.
