Abstract

A method for reclaiming toner dust collector fines in the manufacture of toner is disclosed. The method for reclaiming toner dust fines from a fines collector comprises entraining in water the toner dust that is collected above toner grinders and subsequently returning the tonerlwater slurry back to the extruder through water injection vents for recycling. Presently, large amounts of toner dust collected above grinders are lost as scrap with the accompanying disadvantage of having unnecessary disposal costs. The water based dust collection system disclosed recycles toner dust back to the extruder through water injection vents providing the advantages of reduced loss as scrap and environmentally sound waste treatment.
