Recycled sand is an old sand that has been treated in casting production to restore its performance and can be reused. It is mainly used in the casting industry. During the casting process, old sand (such as used molding sand and core sand) becomes recycled sand after being treated to remove impurities and restore performance. These impurities include adhesive residue, metal shavings, etc. The use of recycled sand can reduce production costs, decrease reliance on new sand, and from an environmental perspective, it is beneficial for reducing solid waste.
