A rotor assembly for a rotary mixer is disclosed. The rotor assembly includes a main drive configured to rotatably drive the rotor assembly, a main drive clutch enclosed in a drivetrain housing of the main drive, an actuation valve operably coupled to the main drive clutch, the actuation valve configured to actuate the main drive clutch between at least a first position and a second position, a rotor drum, a rotor drive gearbox having an input and an output, the gearbox output operably coupled to the rotor drum, a main drive belt rotatably coupled to the main drive clutch and the rotor drive gear box input such that a rotation of the main drive clutch imparts a rotation on the rotor drive gear box, and a speed sensor operably coupled to the rotor drum, the speed sensor measuring a rotational speed of the gearbox and generating a rotor speed signal, wherein based on when the rotor speed signal is below a predetermined rotor speed threshold the actuation valve is activated to rotate the main drive clutch a predetermined amount between the first position and the second position.

A container, such as a disposable or single use bioreactor, optionally having one or more inlets and one or more outlets and a mixer associated with the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The container includes a flexible baffle shaped and positioned within the container to improve mixing, particularly to improve low shear mixing. The baffle is positioned within the container so as to disrupt the vortex formed by the mixer, or prevent formation of a vortex. The baffle is shaped with both horizontal and vertical elements to enhance disruption of the vortex across the entire vessel height and provide homogeneous mixing throughout all operating volumes. In certain embodiments, the baffle is X-shaped.

A food mixer is presented having mixing tool detection capability. The food mixer has a base unit with a tool attachment portion, a mixing bowl attached to the base unit, and a motor attached to the base unit. The motor has operational settings and is configured to apply a torque to the tool attachment portion. A mixing tool is removably attached to the tool attachment portion, and a controller unit of the mixer is configured to detect the mixing tool attached to the tool attachment portion and to automatically control the operational settings of the drive motor based on the mixing tool detected. A magnet carrier may be used to detect a magnetic portion of the mixing tool as it moves with respect to a magnetically-sensitive sensor in the base unit.

A mixing system for producing a drilling fluid for ground drilling includes a feed for a powdered medium and a mixing chamber with a feed for a fluid medium. A space is provided between the feed for the powdered medium and the mixing chamber, having sliding elements therein, which sliding elements can seal off the space at one end.

A method for the application of hydrous mineral binder compositions which contain fibres. An aqueous accelerator is mixed with the aqueous binder composition in a mixer shortly before the application. The method is very robust and makes it possible to quickly produce even large moulded bodies having a uniform surface and very good strength development properties.

A powdery material mixing and feeding device is configured to mix at least two types of powdery materials and to feed a compression-molding machine with the mixed powdery materials. The powdery material mixing and feeding device includes a first mixer configured to rotate about a substantially vertical shaft and to mix the powdery materials, and a reservoir configured to reserve at least a part of the powdery materials, and a second mixer configured to rotate about a substantially horizontal shaft and to mix the powdery materials.

Disclosed is a deagglomeration apparatus, to improve the quality of a mixture used for the production of concrete blocks. An illustrative embodiment of the deagglomerator comprises a vertical shaft high-shear mixer, wherein a rotational force (hydraulic or electric) is mounted to a vertical shaft onto which are mounted chains and/or knives, housed within a flexible rubber boot or tube. The deagglomerator is configured to be controllably powered, to rotate the shaft and the attached tools. Partially mixed formula is introduced to a top region of the deagglomerator, and falls downwardly past the rotating tools wherein the formula is pulverized and mixed, before exiting the lower area of the mixing region.

A mixer unit comprising a mixing chamber comprising a de-agglomerator with a de-agglomeration shaft with de-agglomeration means, a mixer with a mixer shaft with two or more mixing paddles, arranged for mixing and impelling particles and powders in an upstream direction towards the de-agglomerator wherein said de-agglomeration shaft is arranged above, and in parallel with said mixer shaft, so that all particles will be impelled towards the de-agglomerator, each time particles are lifted. Further said mixing chamber comprising a first portion of said mixing chamber having an inner profile adjacent and curved about an upper part of said de-agglomerator and arranged to guide particles and powders impelled by said mixing paddles over said de-agglomeration shaft and into a liquid spray.

The present invention provides a mixing impeller and the like capable of properly performing mixing. A mixing impeller includes multiple blade pairs each having two blades, wherein the blades included in the multiple blade pairs are attached around a rotational shaft extending in a lateral direction, so as to be positioned at a same position in an axial direction of the rotational shaft, the two blades of each blade pair each have a shape that is symmetric about a symmetry plane that is a plane perpendicular to the rotational shaft, the two blades of each blade pair are formed so as to extend from the rotational shaft side toward an outer circumferential side, which is a side opposite to the rotational shaft side, and blade outer portions that are on the outer circumferential side are bent toward a side on which the two blades face each other.

A bioprocess vessel includes a flexible bag or substantially rigid container that defines an interior volume and having a bottom surface, the bottom surface being open or containing an aperture therein for the passage of fluid. A pump is secured to the bottom surface of the flexible bag or substantially rigid container. In some embodiments is secured directly to the flexible bag or substantially rigid container. In other embodiments, the pump is secured indirectly the flexible bag or substantially rigid container using, for example, a port that extends through the aperture on the bottom surface. The port or flanged surface may also be integrated into the pump, which is secured to the vessel. An optional mixing adaptor may be provided inside the interior volume of the flexible bag or substantially rigid container and at least partially covers the inlet that leads to the pump.
