摘要： An apparatus and a method for cleaning sand used at a foundry, wherein sand to be cleaned is screened (22) by a screening apparatus (5). The screened sand and at least one liquid mixture is fed (23) into an abrasive apparatus (6). After that, the screened sand is rubbed (24) by the abrasive apparatus (6). The rubbed sand and at least one liquid mixture is added (25) to a water separation screen (8) for separating (26) a water blend (A) from the rubbed sand. Finally, the separated sand is transferred (27) into an oven (1) and cleaned (28) thermally by rotating the separated sand in the heated oven (1).

摘要： Provided is a method of producing foamed sand (s) for forming a sand mold. The foamed sand (s) includes sand particles (p) and foam (f) adhering to surfaces of the sand particles (p). The foam (f) contains water glass (b), water (w), and a surfactant (c). According to the method, an aqueous surfactant solution (e) in which the surfactant (c) is dissolved is frothed to generate froth (d) from the aqueous surfactant solution (e). Then, the generated froth (d), the water glass (b), and the water (w) are kneaded with the sand constituted by the sand particles (p).

摘要： The invention relates to a device (1) for reprocessing and cooling foundry sand, comprising a mixing container (2) and a mixing tool that can be rotated about a drive shaft (4), wherein an air feed (7) is provided for feeding air into the container interior. The problem addressed by the invention is that of providing an improved device by means of which a more uniform fluidized bed is achieved, preferably over the entire cross-section of the mixing container, wherein furthermore the proportion of the solid particles entrained by the gas flow should be reduced. This problem is solved, according to the invention, in that the mixing tool has at least two mixing vanes (8) spaced apart from each other in the vertical direction and at least one mixing vane has a mixing blade having a surface that is angled with respect to the horizontal.
