The present invention provides a high shear liquid metal treatment device (1). The device (1) comprises a barrel (2), a rotor shaft (5), a plurality of rotor fans (6, 7, 8), and a plurality of stator plates (9, 10, 11). The a barrel (2) having a longitudinal axis extending between an upper end and a lower end, and having an opening (4, 3) at its upper and lower ends. The rotor shaft (5) mounted centrally through, and parallel to the longitudinal axis of, the barrel (2). The plurality of rotor fans (6, 7, 8) mounted along an axial length of the shaft (5) and within the barrel (2), each rotor fan (6, 7, 8) formed such that its outer end is within a minimum distance of an internal wall of the barrel (2). The plurality of stator plates (9, 10, 11) formed on an inner surface of the barrel (2), the stator plates (9, 10, 11) being located between adjacent rotor fans (6, 7, 8), each stator plate extending from an inner surface to substantially to the rotor shaft (5), each stator plate having at least one passage (17) formed therethrough to allow fluid to pass through the plate; and upper and lower surfaces of each stator plate are formed to be within the minimum distance of an adjacent rotor fan (6, 7, 8). The minimum distance being between 10μm and 10mm. The present invention also provides a method of high shear liquid metal treatment using the device (1). The present invention allows improved treatment of liquid and semi-liquid metals during processing. |
