Vibratory feeding device for compact dedusting apparatus

A dedusting apparatus for cleaning contaminants from particulate material, comprising:

• a housing defining a cleaning area for removing contaminants from particulate material to create cleaned particulate material, said housing including internal structure directing a flow of particulate material to be cleaned of contaminates and a product discharge opening through which cleaned particulate material can be discharged from said housing;
• an infeed apparatus located at an upper portion of said housing to receive a supply of particulate material, said infeed apparatus including attachment flange having an infeed opening therein for the passage of particulate material to be cleaned of contaminants,
• a Venturi chamber positioned to receive particulate material passing through said infeed opening and to remove contaminants from the particulate material by a flow of air passing upwardly through the product discharge opening and into the Venturi chamber, while cleaned particulate material falls through the product discharge opening;
• and
• a carryover deflector frame integrally formed with a chamber extension member that aligns with said internal structure to control the flow of particulate material from said infeed opening into said Venturi chamber.
