  • Powder applicator for particulate material coating
    Patent number: 6511541
    Abstract: A machine for coating particulate material includes a rotatable drum with a solid or perforated sidewall. A boom extends into the drum to support one or more spray nozzles and one or more powder applicators. Particulate material is introduced into the drum and subjected to a solution coating from the nozzles and a powder coating from the powder applicators, while the drum rotates. Air may flow through the perforated drum to facilitate drying of the coating solution and powder. The powder applicators are individually regulated so as to provide even distribution of the powder throughout the length of the drum.
