Moistening screws are used for the transportation, for mixing and for moistening of the materials to be conveyed. If the mixed, moistened material has a tendency to stick, a double screw version is strongly recommended. Due to its combing design a self-cleaning effect is achieved. A special field of application is the dustfree loading of loose ashes into rack body trucks.
