Formula for rate of travel of material over vibrating feeder

Mar 04, 2016 · Bed depth is lurking somewhere in the screen formulae. Apply the screen formulae and the discharge velocity is surely the rate of discharge divided by the exigent cross-section. This should be near enough: or what? Why would you want to know the speed of burden on the vibrating machine anyway? Different layers will move at different speeds.
