Method for preparing ceramsite sand from industrial solid waste by using internal combustion sintering process
The invention belongs to the technical field of recycling of industrial solid waste, and particularly relates to a method for preparing ceramsite sand from industrial solid waste through an internal combustion sintering process. The process comprises the following technological procedures: burdening, grinding, primary granulation, secondary granulation, drying, material distribution, firing in a continuous sintering furnace, crushing, sand making, and screening. A ceramsite sand product produced by the dry granulation internal combustion sintering process has the advantages of favorable wear resistance, low water absorptivity, high strength, low breakage rate and no efflorescence or alkali efflorescence, and can completely replace natural sand and stone and machine-made sand. The method has wide development prospects and a wide application range, can effectively solve the problems of quantitative treatment, environmental pollution, stockpiling and the like of industrial solid waste, can effectively compensate for resource supply reduction of natural river sand, realizes resource utilization, turns the waste into wealth, and creates a green ecological home.
本发明属于工业固废的回收利用技术领域，具体涉及一种工业固废利用内燃烧结工艺制备陶粒砂的方法。工艺技术流程为：配料、研磨、一次造粒、二次造粒、烘干、布料、连续烧结炉烧制、破碎、制砂、筛分。通过干法造粒内燃烧结工艺生产的陶粒砂产品具有良好的耐磨性、较低的吸水率、较高的强度和低的破碎率、无泛霜冒碱现象，完全可以替代天然沙石和机制砂。具有广阔的发展前景和使用范围，可以有效解决工业固废的量化处理、污染环境、堆存等问题，同时可以有效弥补天然河沙的资源供给减少；实现资源化的利用，变废为宝，创造绿色生态家园。
