Embodiments provide a wet disperser for dispersing particulates in a mixture containing at least a dispersing medium and particulates. According to various embodiments, the wet disperser includes a through channel extending from an inflow port to an outflow port, and a mixture-passing plate having at least one passing hole defined. In the wet disperser, the through channel includes, on a downstream side of the through channel from a position provided with the mixture-passing plate, a dispersion part having a vibration body provided such that vibration causes at least a part of the vibration body to come into contact with at least a part of an opening periphery of the passing hole, and an inside surface defining the passing hole of the mixture-passing plate.

An application dispenser for at least one component, in particular for an adjustable dosing and/or mixing dispenser, includes a rotation element, in particular a ball for applying the at least one component, and a pump configured to load the at least one component with pressure and feed the at least one component under pressure onto the rotation element.
