Title: Eductor wand for bulk particulate materials

Abstract: An eductor wand for vacuuming free flowing, bulk particulate materials consisting generally of a first conduit having first and second inlets; a venturi disposed within such first conduit and spaced therefrom to provide a passageway therebetween intercommunicating the first and second inlets of the first conduit and having an inlet disposed adjacent the first inlet of the first conduit and an outlet communicable with a particulate material conveying means; and a second conduit having an inlet connectable to a source of air under pressure and an outlet configured to inject pressurized air into the venturi inlet whereby upon applying air under pressure to the second conduit and positioning the first conduit inlet adjacent a mass of particular material, a low pressure zone will be created in the first conduit inlet causing particulate material to be drawn through the first inlet of the first conduit and ambient air to be drawn through the second inlet of the first conduit, and such particulate and ambient air to become entrained in the pressurized air injected into and through the venturi.
