Abstract
A compact dedusting apparatus is mounted on the machine utilizing particulate material requiring contaminant cleansing to provide an economical and effective decontamination of particulate material immediately before utilization of the material. The dedusting apparatus includes a downwardly sloped infeed chute having an opening at the bottom thereof. A metering device in the form of a rotatable finned hub blocks the opening to constantly meter the flow of particulate material through the dedusting apparatus. The metering device is formed with flexible blades oriented at a slight angle to the slope of the infeed chute to provide a constant flow of material through the opening. A flow of air is directed through a wash deck positioned below the infeed chute to cleanse the particulate material. The air flow is directed along multiple paths including a path defining an air knife associated with the wash deck to facilitate the cleansing of the material.
