A method for preparing semisolid slurry. The method is achieved using a device for preparing semisolid slurry. The device includes a slurry vessel and a mechanical stirring rod. The mechanical stirring rod includes a first end and a second end extending into the slurry vessel. The method includes: S1. putting a molten alloy having a first preset temperature into the slurry vessel; S2. cooling the molten alloy to a second preset temperature, positioning the second end of the mechanical stirring rod to be 5-25 mm higher than the bottom wall of the slurry vessel, rotating the mechanical stirring rod and injecting a cooling medium into the mechanical stirring rod; and S3: allowing the temperature of the molten alloy to be 10-90 degrees centigrade lower than the liquidus temperature of the molten alloy, stopping stirring and cooling, to yield a semisolid slurry.

Mixing machine

A mixing machine includes a mixing head and at least one connection means for connecting a mixing container containing material to be mixed to said mixing head for forming a closed mixing container. The mixing head, as part of a pivotable assembly, is pivotably mounted with respect to a frame such that the closed mixing container formed from the mixing head and the mixing container can be pivoted relative to the frame for performing the mixing process. The mixing head carries at least one rotationally-driven mixing tool. The mixing head comprises a head plate having a connecting flange molded thereon which is configured as an annular disc and comprises a planar contact surface. At least two ring seals of differing diameters are arranged in said contact surface of the connecting flange at a spacing between each other, such that mixing containers with different connection diameters of their mixing head side can be connected to said mixing head. The at least one connection means is configured for gripping mixing containers which differ in the diameter of their connection sides.
