Description

ABSTRACT:
A mixer-pump has a rotor shaft with a set of pins intermeshing in pins extending inwardly from a cylindrical stator to mix together materials flowing axially through the cylinder. The pins are generally cylindrical in shape except for a set of pins on the rotor shaft designated pumping pins which ae half cylindrical with their flat faces oriented to impart a longitudinal direction of travel of materials through the cylinder. Flow throughput is still further enhanced by a set of axially positioned vanes extending from the housing inwardly toward the rotor shaft with curved ends forming a scoop to receive materials being given a rotary flow component about the shaft by its rotation and convert the flow direction to an axial flow path.
