  • Patent number: 5257691
    Abstract: An arrangement for transferring castable material without pipes or conduits from a feeding point to a destination, particularly in underground mining. The arrangement includes a driven centrifugal wheel with blades. The centrifugal wheel is radially open and is surrounded in the manner of a jacket by an endless housing belt which is guided on guide rollers. The portion of the centrifugal wheel which is radially open is bordered by the guide roller which causes the housing belt to contact the centrifugal wheel and by the guide roller which raises the housing belt from the centrifugal wheel. The material is radially discharged in a concentrated manner through this radially open portion. The material is supplied axially to the centrifugal wheel through a feed tube and enters through a discharge opening of the feed tube on the vertical level of the blades into the centrifugal wheel.
