    Abstract: An embodiment of a distribution device for a slurry containing liquid and solid constituents, including a housing, a rotor, a driving unit, and an annular air transmission chamber. The housing includes an inlet, end walls at a driving side and opposite, and a plurality of outlets. The rotor is arranged in the housing and rotatable about a rotation axis, with at least one blade arrangement for sweeping over the outlets and an air distribution chamber for distributing compressed air to the blade arrangement(s). The driving unit has a motor outside the housing and a drive shaft coaxial with the rotation axis which passes through the end wall at the driving side and is connected to the rotor. The transmission chamber is coaxial with the rotation axis, outside the drive shaft, and is connected to the air distribution chamber and an inlet for compressed air, in an air-conducting manner.

    Abstract: Subject matter of the invention is a cutting ring for solids-loaded fluid of a pump, comprising a cutting ring base body forming an opening for cooperation with a cutting head, which cutting ring can be stationarily connected to the pump in an axial extension of an impeller of the pump, wherein



    a plurality of cutting teeth comprising respectively at least outer cutting edges oriented away from the impeller in the direction of a suction side of the pump are provided at the cutting ring base body around the opening, wherein the cutting teeth extend axially away from the cutting ring base body outwardly at least in the direction of the suction side, and
    at least in the outwardly extending cutting teeth a respective radially outwardly extending material recess is formed, and/or
    a radially outwardly extending axial depression is formed in the cutting ring base body in a valley between two at least outwardly extending cutting teeth.

    Abstract: A solids dissociation apparatus that is used to remove various types of contaminants from a continuous fluid stream. The solids dissociation apparatus includes a housing. The solids dissociation apparatus also includes at least one insert that is operably engaged with the housing where the at least one insert is adapted to receive a continuous fluid stream. The solids dissociation apparatus also includes a transducer that is operably engaged with the housing and disposed about the at least one insert at a distance away from the at least one insert inside of the housing. The transducer is configured to create cavitation inside of the housing, via sonic waves, to eviscerate contaminants in the continuous fluid stream flowing through the at least one insert.

    Abstract: Described is a macerator and process for using the macerator to reduce the particle size of a particulate containing slurry that is introduced to the macerator. The macerator comprises a housing that defines a chamber an inlet and an outlet, the inlet configured to receive a flow of slurry, two or more elongate concentric bodies located within the chamber to define a gap between the surface of the outer body and the inner surface of the housing, the bodies having a first end and a second end, at least one of the bodies rotatable about an axis, and each body comprising a plurality of apertures to define a flow path through each body, from the housing inlet to the housing outlet, a baffle or baffles that extend substantially the width of the gap from the first end to the second end of the bodies to define a first portion that contains the inlet, and a second portion that contains the outlet, and wherein the baffle or baffles substantially inhibit passage of slurry between the two portions via the gap such that the slurry is directed through the body apertures, a motor to drive the rotating body or bodies, one or more injectors that inject liquid into the gap, wherein at least one of the injectors is located in the first portion. The particle size of the outlet slurry is less than the particle size of the inlet slurry.
