Scaling for horizonal media mills PCI Mag

Oct 04, 2000 · Power Consumption. For example, if a one-minute residence time is used as a baseline on the one-liter mill, the flow rate would be about half the volume of the mill per minute (based on volume taken up by beads). So, theoretically, a 500-liter mill would give about 250 liters per minute flow rate with a direct scale up.
