Abstract
An improved solids pump apparatus for transporting and metering particulate material including a transport channel having an inlet and an outlet. The transport channel is formed between substantially opposed faces of first and second rotary disks movable between the inlet and outlet towards the outlet and at least one arcuate wall extending between the inlet and outlet. The apparatus further includes a device provided adjacent the inlet for preventing a dead area from being formed to thereby provide a constant and uniform flow of the particulate solids within the apparatus.
