Description

かくして本発明によれば、シェル殻を０〜４０重量％含む生型廃砂を、乾式ロータリーリクレーマーによる乾式磨鉱を１〜５パス施すことで生型廃砂表面に付着している粘土分を主成分とする不純物を８０重量％以上除去した後、総粘土分が０．３重量％以下となるようにトラフ式磨鉱装置による湿式磨鉱を１〜５パス施すことで、鋳型用骨材に再生することを特徴とする生型廃砂の再生方法が提供される。
更に、本発明によれば、上記再生方法により得られる鋳型用骨材が提供される。 Thus, according to the present invention, the raw waste sand containing 0 to 40% by weight of shell shells is subjected to 1 to 5 passes of dry grinding with a dry rotary reclaimer, thereby adhering the clay content adhering to the surface of the raw waste sand. After removing 80% by weight or more of the main impurities, the mold bone is subjected to 1-5 passes of wet grinding with a trough grinding machine so that the total clay content is 0.3% by weight or less. There is provided a method for regenerating green waste sand, characterized by regenerating the material.
Furthermore, according to the present invention, an aggregate for a mold obtained by the above regeneration method is provided.
