### Grinding time for ball mills - Grinding & Classification ...

This is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m³/h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time.
