Abstract:The construction of a rotary vane-type solid feeder valve is described. It is shown that at low speeds the rate of solids flow through the valve is directly proportional to the rate of revolution. At higher speeds, the rate of increase of solid feed rate falls off until the rate becomes constant when the rate of solid flow through the rectangular orifice is limiting. The rate of flow through the valve is correlated by an equation that links the speed and geometry of the valve to the properties of the solid.
