A process involving: collecting waste toner; screening the collected waste toner; melt mixing the screened waste toner with a second toner, and grinding and classifying the melt mixed toner product.

Process for producing toner

An apparatus in which toner fines are recovered from a recirculating liquid transporting toner pellets cut from extruded toner. The recirculating liquid cleans the pellet cutter and forms a mixture of liquid and toner fines. The recovery unit is positioned between the pellet cutter and a station discharging the pellets. In this way, clean liquid flows into the pellet cutter during each cycle. The recovery unit has a housing defining a chamber having two sections. A sloping screen is located in the chamber covering one of the chamber sections. The mixture of toner fines and liquid is dispensed onto the screen. The liquid passes through the screen and is recirculated. Toner fines collect on the screen. A backwash system washes the toner fines from the screen into the other section of the chamber. The mixture of toner fines and liquid is pumped from the other chamber section into a separator. The toner fines are separated from the liquid and re-used in the extruder. Liquid from the separator is returned to the other chamber section.
