ABSTRACT:
A particulate material accelerator conveyor includes a housing having a wall with openings therein for an air inlet, a particular material inlet, and a mixture outlet; a feed auger rotatably mounted in the housing and in fluid communication with the particulate material inlet so as to convey particulate material from the inlet into an acceleration chamber within the housing; and a fan rotatably mounted in the housing in fluid communication with the air inlet and the acceleration chamber. The fan includes a plurality of fan blades for accelerating air from the air inlet toward the housing wall and thereby providing a flow of accelerated air along the inside of the wall and toward the particulate material and move therewith toward the mixture outlet. The positioning of the fan in the housing and the resulting air flow therefrom prevents particulate material from contacting the fan blades and thereby damaging the particulate material. An impeller can be rotatably mounted in the housing between the auger and the fan so as to mechanically accelerate the particulate material before the air flow further accelerates it. The impeller can also help isolate the particulate material from the fan blades.
