A mixing bit having an elongated shaft configured to fit into a chuck of a drill at a first end also has a second end is provided with a blade assembly having a plurality of specifically shaped and equally-spaced blades. The blades extend perpendicularly from the shaft and then converge onto the shaft at a distal end of the second end. The bit is provided with a rounded spinner feature enabling smooth sliding of the device across a floor portion of a container during mixing.

A stirring/mixing device is provided, comprising a container and a motorized stirring element that permits substances within the container to be stirred without an attendant. In a preferred embodiment, two blades are provided that are shaped to push material away from the wall of the container and fold the substances together so as to provide a substantive mixing of whatever is placed within the container. The device can be configured so that mixing is controlled by a panel or remote control and the speed and direction can be adjusted, such that proper mixing is achieved without direct supervision. To provide proper force, the blades can be attached on a gear drive that rotates about the opening of the container

A stirring device, in particular an axially conveying stirring device, is proposed for stirring, mixing, homogenizing, dispersing and/or suspending in particular abrasive media, with at least one stirring blade which is configured to rotate about a rotary axis, and with a contour unit which is configured for reducing wear-down of the at least one stirring blade.

A mixer for insertion into a rotor of a centrifuge has a mixing trough and an obstacle device with at least one obstacle. The at least one obstacle is configured in order to influence the flow of a liquid present in the mixing trough. In response to a rotation of the rotor, with a specified incorporation of the mixer in a holder of the rotor, a spacing between at least one wall section of the mixing trough and the obstacle device is variable such that the liquid present in the mixing trough flows around the obstacle of the obstacle device.

A mixing segment for an extrusion apparatus comprises a shaft and a plurality of plow elements aligned along a helical path extending about a rotation axis of the shaft. Each plow element includes an outer peripheral arcuate ramp extending radially outwardly along the helical path from a root to an outer tip of the plow element. Methods of manufacturing a mixing segment and methods of manufacturing a honeycomb structure with an extrusion apparatus are also provided.
