Abstract
Apparatus and method for feeding particulate material from a hopper into a process stream at a controlled flow rate. A rotating wheel with spaced apart pockets is vibrated to densify the particulate material in the pockets. A stator contacts and covers a portion of the upper surface of the wheel and has a transfer station connected to discharge particular into the process stream. The wheel is driven in rotation at a controlled rate to control the particulate flow rate into the process stream. A conveying gas supply projects a jet of gas into the pockets for removing the particulate material and conveying it into the process stream. An aerating gas supply directs an upward flow of gas from the periphery of the wheel, through the particulate material being supplied to the wheel to fluidize the particulate material supplied to the wheel.
