Claim:
1. An injector head for coating a particulate material while delivering the particulate material from a feeder source to a receiver; said injector head including: a sidewall or walls defining a chute which circumscribes an interior space through which the particulate material flows, said chute having an open top and an open bottom, both circumscribed by said sidewall or walls; a centerline which extends vertically through the interior space and a middle of the injector head; a plurality of splitter bars, each of said plurality of splitter bars having a top, sides, a first end, a second end, a bottom, and a length extending from the first end of each of the splitter bars to the second of each of the splitter bars, said plurality of splitter bars provided for dividing flow of the particulate material passing through said chute, such that the flow of the particulate material flows past and forms curtains of the particulate material to either side of each said splitter bar; and a plurality of spray nozzles for spray coating the particulate material; said splitter bars extending laterally from said sidewall or walls into said interior space through which the particulate material flows; each of said spray nozzles being mounted to said sidewall or walls directly below one of said splitter bars, for spraying coating material away from said sidewall or walls and laterally relative to the length of said splitter bars into the interior space of each side of said splitter bar towards the centerline of the injector head so as to coat the particulate material as the particulate material passes over to the sides of said splitter bars; each of said splitter bars is mounted to the sidewall or walls at the first end of the splitter bar and the length of each said splitter bars terminates before the middle of the injector head with an open space extending between the middle of the injector head to the second end of each of said splitter bars; wherein the length of each splitter bar extends inward towards the centerline of the injector head and the second end of each of the splitter bars is separated from the second end of an adjacent splitter bar by the open space extending from the middle of the injector head; each of said splitter bars having a width sufficient to create a space between said curtains of particulate material flowing over and to the sides of said splitter bar, and the particulate material which has been coated collects in the receiver located below said open bottom of said chute.
