  • Dust reduction in delivery of particulate commodities
    Patent number: 8297541
    Abstract: Apparatus for reducing dust emissions from particulate commodities such as wheat or coal using a curved loading spoon connected to the discharge from a loading spout. The curved loading spoon turns particulate commodities delivered at a rate above a predetermined delivery velocity against a curved outer wall causing dust arising from the particulate commodities to be re-entrained within the commodities as they are diverted from a straight path by the curvature. Also described are an optional flap designed to rest just above the surface of the commodities stream adjacent the outlet, and a converging duct located upstream of the curve loading spoon and arranged to direct commodities against the curved outer wall adjacent the inlet.
