Abstract: A method for regenerating foundry sand, in particular for the renewed production of foundry molds and/or foundry mold cores from the regenerated foundry sand, through removal of binding agent, from a foundry sand/binding agent mixture, using a solid support means (6), wherein binding agent and support means (6) are separated from the foundry sand, wherein support means (6) is brought into contact with the foundry sand/binding agent mixture, is preferably added to it, and, together with the binding agent, which adheres thereto and/or which is incorporated therein, is separated from the foundry sand (10).

Abstract: A spreading device for a pneumatic application of brake sand on rail-mounted vehicles, comprising an air source and a sand container as storage container for the brake sand or the spreading material, an outlet at the lower end of the sand container, a connecting pipe to a mixing container provided for air-charged swirling of the spreading material to form a sand stairway and a dispensing device disposed on the mixing container for the specific dispensing of the spreading material onto the rails in front of the wheels.
