  • ROTATABLE FEED DISTRIBUTOR
    Publication number: 20190184403
    Abstract: A feed distributor includes a rotatable chute mounted and suspended within a housing. Respective drive components for the rotatable chute are mounted within a working part zone defined by the housing. Such drive components are protected from dust and particulate contamination by a plurality of seal rings and/or an air feed assembly configured to create a positive pressure within the working part zone and a corresponding exhaust air flow at specific regions of the housing.
