Abstract (en)
[origin: DE19945569A1] The present invention relates to a method for conditioning moulding sand. Conditioning is at least partially carried out under a vacuum. The present invention also relates to a device for carrying out said method. Moulding sand that is not cooled under a vacuum is heated before or during conditioning and is subsequently cooled under a vacuum influence. Conditioning of the moulding sand under vacuum is thus guaranteed regardless of the temperature of the sand. Moreover, cooled moulding sand is provided for further treatment. The re-conditioned moulding sand is provided with quality values that remain equally high regardless of the temperature of the moulding sand.
