Abstract: An agitator device has at least one intermediate bearing which is configured for supporting an agitation shaft within an agitation tank and which has a first bearing element and a second bearing element which, in an operation state, is rotatable relative to the first bearing element around a bearing axis and is in contact with the first bearing element, wherein at least one of the bearing elements has polycrystalline diamond.

Abstract: A stirring element device, in particular for stirring fluidized beds and/or solid matter mixtures and/or highly viscous suspensions, comprises at least one helical stirrer, which is rotatable around a rotation axis and has at least one winding that runs around the rotation axis, wherein the helical stirrer comprises a base body, which has in at least one cross-sectional view an at least section-wise oval, in particular circle-shaped, outer contour.

Abstract: A method in which a medium viscous to highly viscous fluid and/or a medium viscous to highly viscous suspension are/is mixed by means of an agitator device that is driven by a drive shaft, wherein the fluid and/or the suspension are/is brought into a multi-dimensional flow by means of a close-clearance stirring blade (14) of the agitator device, and a flow resistance is minimized along a shaft direction in a shaft proximity.

Abstract: A stirring device, in particular reactor stirring device, has at least one holder which is configured for holding at least one brittle unit within a container relative to at least one container wall of the container, and which has at least one holding unit for this purpose. At least one holding position of the holder relative to the container wall can be adapted by means of the holding unit.

Abstract: 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.

Abstract: A stirring device has at least one at least substantially metallic stirring blade carrier and a plurality of stirring blades, which are connected to the stirring blade carrier, wherein the stirring blades are at least substantially made of a non-metallic material, wherein the non-metallic material is a ceramic material, wherein the stirring blades are releasably connected to the stirring blade carrier, wherein it is possible to release and/or establish a mechanical, namely a negative-fit and/or positive-fit connection between the stirring blades and the stirring blade carrier in a damage-free and/or non-destructive manner, and wherein the stirring blade carrier comprises at least one recess, which is configured to at least partly accommodate at least one of the stirring blades. The recess comprises at least one partial region implemented in a contiguous fashion if viewed in parallel to a rotational axis of the stirring blade carrier.

Abstract: A system for dispersing finely dispersed solids into high-viscosity products includes, in a container, a coaxial stirring system having stirring elements on two independently drivable, coaxially arranged shafts. A positive-displacement, close-wall-clearance stirring element on the one shaft and a plurality of stirring elements on a central shaft are arranged in such a manner that, in an upper mixing region of the container, a combination of the positive-displacement, close-wall-clearance stirring element and stirring elements for forming an ideally mixed zone is provided, and in a mixing region downstream of the upper mixing region of the container, stirring elements for developing a plug-flow zone are provided. A positive-displacement pump is provided in a region downstream of the plug flow zone as a discharge zone.
