The invention provides a method for preparing mullite sand from solid waste materials, and belongs to the technical field of mullite sand preparation.The mullite sand is prepared through the process steps of crushing, deironing, sieving, fine grinding, drying and the like of the solid waste materials, the solid waste materials formed after a mullite sand mold of a precision foundry is used as raw materials, the resource utilization rate is increased, and the cost is reduced. According to the present invention, the process is simple, the resource waste and the environmental pollution are avoided, the resource damage caused by the mine mining is avoided, the water milling is used in the process, the high energy consumption and the high carbon dioxide emission are avoided, the dust is avoided, the working environment is optimized, the process flow method is simple, the production cost is reduced, and the high economic benefit is provided.
本发明提供了一种利用固废物料制备莫来砂的方法，属于莫来砂制备技术领域，本发明通过将固废物料进行破碎、除铁、过筛、细磨、烘干等工艺步骤制得莫来砂，原料使用精密铸造厂莫来砂模具使用后形成的固废物料，提高了资源利用率，避免了资源的浪费和环境污染，同时免去矿山开矿造成资源破坏，工艺使用水磨，免去了高能耗和高排放二氧化碳，无粉尘，优化了工作环境，本发明工艺流程方法简单，降低了生产成本，具有较高的经济效益。
