A mixer for mixing concrete components comprises a chassis and a mixing drum mounted for rotation with respect to the chassis and having an open end. The chassis includes a lifting structure extending beyond the open end of the drum and a support structure spanning the open end of the drum. The mixer is moveable between an inverted orientation in which the open end of the mixing drum faces generally downwards and a mixing orientation in which the open end of the mixing drum faces generally upwards. The lifting structure is arranged to engage with a container with the mixer in the inverted orientation, and to lift and invert the container upon movement of the mixer to the mixing orientation. The support structure is arranged to support the inverted container above the mixing drum when the mixer is in the mixing orientation. Also, a method for producing a concrete mix.

Blending devices can be used to blend material directly in a container such as a disposable container, such as a paper or plastic cup. In some instances, a disposable container can be coupled to an adapter that includes a blade assembly to blend a food product. The food product can be blended directly within the container when the container is coupled to the adapter and supported with a support sleeve that at least partially surrounds an exterior of the disposable container. In further instances, a stand can selectively couple with multiple different sizes of sleeves and disposable containers to the adapter. The food product can be blended directly within the disposable container without causing damage or flex to the disposable container.

A sample tube includes a cylindrical wall and a first end and a second end. The first end of the sample tube is closed by a base, such that a sample-receiving space with a longitudinal axis is formed between base and cylindrical wall. The second end has a closure piece connected releasably thereto. A weight element is received inside the receiving space and is shaped and dimensioned in such a way that the weight element can rotate freely in the receiving space only about the longitudinal axis of the latter. The application further relates to a method and a device with which a sample located in the sample tube can be dispersed or homogenized by rotational movement of the sample tube.

A time-varying detecting device and method for concrete rheological parameters, in which the double-covered cylinder has top and bottom covers (11, 12), both of which can be freely opened, is configured to contain a concrete sample, and a lifting frame includes a pair of vertical supports (21) extending in parallel with each other. The double-covered cylindrical container is held between the pair of vertical supports (21) by means of connecting members (30) in such a manner that it can be flipped 180° about a straight line along which the connecting members (30) extend under the action of an external force. To perform a test, the top cover (11) is opened and a concrete mix is filled in, followed by detecting initial rheological parameters. The top cover (11) is closed, and the concrete mix is left for a predetermined period of time. The double-covered cylindrical container is lifted to a predetermined height by raising the connecting members (30), flipped 180° and lowered back onto the floor. The bottom cover (12) is opened, and the concrete mix is re-mixed and homogenized, followed by finally detecting the time-varying rheological parameters of the concrete mix.

An industrial mixing machine comprises a mixing head and at least one attachment means for attaching a mixing container, which contains a material to be mixed and is open on the attachment side, to the mixing head to form a closed mixing receptacle. The mixing head is pivotably mounted in relation to a frame as part of a pivotable assembly in such a way that the closed mixing receptacle formed from mixing head and mixing container is pivotable in relation to the frame to carry out the mixing process. The mixing head has at least one mixing tool, which is seated on a drive shaft extending through the mixing head and rotationally driven thereby, having multiple radial blades. The radial blades have a cross-sectional geometry according to which, starting from its maximum thickness, the blade thickness decreases in the rotational direction toward the rear blade end. In the section of decreasing blade thickness, the blade lower side is pitched more strongly with respect to the horizontal in the rotational direction than the blade upper side. An imaginary straight line connecting the rear end of the radial blades to their respective front end facing in the rotational direction is inclined in relation to the horizontal in the same direction as the inclination of the blade lower side in the section of decreasing thickness.
