Abstract

Disclosed is an article and method for modifying the air nozzles in an existing fluidized bead grinder so as to prevent the nozzles from plugging on shutdown. Presently, on grinder shutdown, toner is sucked back into the nozzles from the grind chamber due to negative back pressure and leads to fouling or clogging of the nozzles. A solution provides for each of the three nozzles be modified with a mechanism similar to that of a bolt action rifle. Just prior to shutting the grinder down, an action bolt or plug rod is pushed forward into the nozzle interior free space so that a small diameter rod at the end of the action bolt goes through the nozzle orifice to stop ground toner from getting back into the nozzle and the upstream air supply.
