Abstract

The present invention concerns a casting sand cooler comprising a sand chamber having an air inlet optionally with a fan for the feed of air into the sand chamber and an air outlet optionally with a fan for sucking air out of the sand chamber. To provide an improved casting sand cooler in which the sand discharge during the cooling operation by way of the air outlet is markedly reduced, it is proposed according to the invention that a dynamic wind sifter which is rotatable about an axis and which is so arranged that substantially the complete air flow leaving the sand chamber through the air outlet is passed through the dynamic wind sifter.
