C A N A D A INVENTION PARTICULATE MATERIAL LOADER INVENTOR JAROSLAV KOPERNICKY ABSTRACT OF THE DISCLOSURE A filterless loader which entrains particulate material in air flows is described. The loader includes a reservoir in which the materials may be accumulated and from which the materials may be delivered under gravity through a, lowermost outlet to appropriate processing, equipment. A closed air circuit draws the particulate material into the reservoir from an external storage bin or container. The closed air circuit includes air supply and return conduits communicating with the interior of the reservoir, and a fan unit which circulates air through the conduits. The fan unit draws air from the interior of the reservoir, and forces the air into an inlet end of the supply conduit. A gap is maintained at the junction of the air supply and return conduits external to the reservoir, and supply conduit air flows are guided by a nozzle across the gap into the return conduit. The junction is inserted into the storage container thereby introducing the particulate material into the path of the closed air circuit. An air flow diffusing region between the return conduit and the air inlet of the fan unit causes particulate materials entrained in the return air flows to settle to the bottom of the reservoir where they can be delivered under gravity to the processing equipment. Particulate material is confined to the closed circuit air flows therehby preventing scattering to the environment, and no filter commonly used in prior loaders is needed to reduce emission of particles.
