Abstract
In a belt arrangement including two endless belts revolving about deflection cylinders with their axis parallel to each other, for transporting loose, finely divided material, the upper sections of which belts are in approximately the same plane, the belts being driven in the same transport direction and following each other immediately in the transport direction and thus forming an upper wedge space between the two belts; an auxiliary device for transferring the material from one belt to the next one is obtained by means of a liquid which is of higher specific gravity than the material to be transported and does not wet the latter disposed in the upper wedge between the last deflection cylinder of the one belt and the first deflection cylinder of the following belt with seals sealing said wedge at the bottom and sides to retain the liquid.
