Abstract: A blender has a tubular mixing chamber that is provided with an interior and is arranged horizontally. A fill opening and an outlet opening communicate with the interior of the tubular mixing chamber. The fill opening and the outlet opening are spaced apart from each other in an axial direction of the tubular mixing chamber by a length distance. A rotatably driven shaft extends in the axial direction lengthwise through the interior of the tubular mixing chamber and is provided with mixing members that are projecting radially outwardly into the interior of the tubular mixing chamber. The shaft has a region without mixing members, wherein the region without mixing members is located in front of the outlet opening and adjoining the outlet opening. The region without mixing members has a length that amounts to between ? of the length distance and ½ of the length distance.

Abstract: The invention relates to a device for depositing a surface coating on cores. The inventive device comprises a rotationally mounted drum for accommodating the cores, at least one spraying nozzle for depositing the surface material on the cores, a heating device for the inner space of the drum, an inlet and an outlet, and carriers which are provided for the cores and which are arranged inside said drum. The invention provides that the drum is designed as a longish cylinder and that second carriers are provided for the cores (11, 12). The second carriers transport the cores opposite the first carriers and are arranged such that they can be radially displaced in relation to the first carriers. The invention also provides that the drum is held in the device so that it can be quickly removed.
