| A return sand cooling system, including: a sand moisture and temperature measuring instrument measuring the moisture content and temperature of the return sand; a control device determines an appropriate water addition amount, which is an amount of water to be added to the return sand; a water-sprinkling cooling device adds water of the appropriate water addition amount to the return sand and cools the return sand by the latent heat of vaporization of water to obtain the cooled return sand; an air introducing device that introduces air into the water-sprinkling cooling device; and an introduced air temperature and humidity measuring instrument measures the temperature and humidity of introduced air to be introduced into the water-sprinkling cooling device; the control device determining the appropriate water addition amount on the basis of the moisture content and temperature of the return sand, and the temperature and humidity of the introduced air. | ||||||

| 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. | ||||||

| The present invention concerns an apparatus for treating and cooling foundry moulding sand, comprising a mixing container and a mixing tool rotatable about a drive shaft, wherein there is provided an air feed for the feed of air into the container interior. To provide an improved apparatus with which a more uniform fluidised layer is produced as far as possible over the entire cross-section of the mixing container, wherein moreover the proportion of the solid particles entrained with the gas flow is to be reduced, it is proposed according to the invention that the mixing tool has at least two mixing vanes spaced from each other in the vertical direction and at least one mixing vane has a mixer blade with a surface which is inclined relative to the horizontal. | ||||||
