An assembly for insertion into a holder of a mixer, comprising: a dispenser having an exterior surface of which at least a band is symmetric about a longitudinal axis of the dispenser; and an adapter for surrounding at least the band of the exterior surface of the dispenser. The adapter comprises a closeable shell, the shell being configured to lock the dispenser in at least a region of the band so as to impede rotational slippage of the dispenser relative to the adapter about the longitudinal axis with the shell being closed. If the assembly is then locked to/engaged with the holder of a planetary mixer, this causes the assembly to undergo superimposed revolution and rotation movements in tandem with those of the holder, resulting in a desired level of mixing being imparted to the dispenser's contents, which may improve homogeneity and predictability of the mixing results.

A dispersing device is provided by which a dispersion with a high yield and a proper dispersing process can be carried out. The dispersing device causes a mixture of a slurry or a liquid to flow by centrifugal force toward an outer circumference between a rotor and a stator. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face a lower surface of the stator, and an assembly for supplying the mixture that stores an unprocessed mixture to be supplied to a gap between the rotor and the stator. The assembly for supplying the mixture has a body, a first member for injecting the mixture, and a second member for injecting the mixture.

A base unit device for effective mixing and dispensing of a material, and for quick and efficient cleaning of all components. The base unit defines a base internal cavity, and a removable auger and a removable mixer each rotatably located in the base internal cavity. A mixer support ledge of the mixer can overlap an auger support ledge of the auger to prevent the auger from being withdrawn from the base unit when the mixer and the auger are operatively assembled with the base unit. The mixer can include a locking end featuring locking tabs that can engage with a surface of a sidewall of the base unit that defines a mixer bore, thereby locking the mixer and the auger in position during operation. The base unit can be utilized with a hopper defining a hopper internal cavity for storing the material and providing it to the base internal cavity.

Various measures increase the cooling effect on a planetary roller extruder section/module. Those measures include a choke being arranged at an outlet of the planetary roller extruder section or module, a distance between centerlines of adjacent planetary spindles being at least equal to an outer diameter of the planetary spindles, providing a pressurized melt supply, having a cooling section composed of several sections/modules, providing at least one section/module in which a flow, during melt supply is converse to the conveying direction of the extruder, and providing cooling tubes arranged within the central spindle.
