A granular material stirring apparatus for breaking up clumps of a granular material in an interior of a storage bin comprises a base assembly for resting on a floor of the bin, an agitation rotor rotatably mounted on the base assembly, and a rotation device connected to the rotatable agitation rotor to cause the agitation rotor to rotate with respect to the base assembly. The agitation rotor may include a central member rotatable about a substantially horizontal axis and a plurality of stirrer members extending substantially radially outwardly from the central member to rotate about the substantially horizontal axis.

A wet powder manufacturing apparatus includes a housing being arranged such that a central axis CL of the cylindrical inner surface extends in a substantially horizontal direction, a plurality of stirring blades provided rotatably about the central axis CL, a rotary plate configured to rotate the stirring blades about the central axis CL such that the wet powder accumulated at the bottom of the cylindrical inner surface is scooped by the stirring blades and then dropped, a driving device configured to impart a rotary force to the rotary plate, a liquid diffusing device configured to diffuse liquid into the drum inner space so as to wet the powder, and a controller configured to control operations of the driving device and the liquid diffusing device. The controller includes control for vibrating the stirring blades.

A biogas plant contains a fermenter vessel, in which an assembly support is mounted, preferably vertically oriented. An assembly, in particular a submersible motor driven stirrer, is retained by a height adjustment device so as to be vertically adjustable on the assembly support. Accordingly, the height adjustment device is formed by a belt drive of which a traction device is guided around at least two deflecting elements spaced apart from one another in the longitudinal direction of the assembly support. At least one of the deflecting elements can be driven in rotation by a driving device and the assembly is coupled to the traction device in such a way that when the deflecting element is rotationally actuated in a first direction the assembly is raised and when the deflecting element is rotationally actuated in a second, opposite direction, the assembly is lowered.

A centrifugal dispersion device is provided. The centrifugal dispersion device includes a cylinder body, multiple rotor units, and multiple stator units. The cylinder body is internally provided with a shaft core. Each rotor unit includes a rotor inner cylinder, a rotor outer cylinder, and a rotor rib-plate. The rotor inner cylinder is fixedly sleeved on the shaft core and rotatable along with the shaft core. The rotor inner cylinder and the rotor outer cylinder cooperatively define a rotor cavity. Each stator unit includes a stator cylinder and a blocking portion. The stator cylinder is fixedly connected to an inner wall of the cylinder body. The blocking portion extends from an inner wall of the stator cylinder into a gap between adjacent two of the multiple rotor units. A first flow-passing channel is defined between the inner wall of the stator cylinder and an outer wall of the rotor outer cylinder.
