    摘要： 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.

    摘要： For regenerating the sand, which is obtained from sand molds and/or sand cores, which are produced from the sand and soluble glass as a binder and are used in metal casting, the sand obtained from the sand molds and/or sand cores is subjected to a mechanical regeneration stage and a thermal regeneration stage. During or after the mechanical regeneration stage, the obtained sand is mixed with a hardener for soluble glass.

    摘要： A method and apparatus are provided to process collected sand. This method and apparatus allow the moisture content to be adjusted and the addition of a binder to be facilitated to renew the collected sand as casting sand for future use. Also, defective castings are prevented when they are made by a main mold using the renewed casting sand. The sand-collecting means can be compact. The method is performed and the apparatus is operated by separating a main mold of green sand, after casting is conducted, into parts unaffected and affected by the molten metal heat, adjusting the moisture content of the part unaffected by molten metal heat for use as facing sand in the next main mold making, and adding a binder and adjusting the moisture content of the part affected by the molten metal heat for use as back sand in making the next main mold.
