Light ceramsite sand and preparation method thereof
The invention discloses light ceramsite sand and a preparation method thereof. The light ceramsite sand comprises the following components in percentage by weight: 80 to 95% of industrial sand making solid waste wet material, 3 to 10% of sodium sulfate or magnesium oxide, 1 to 5% of coal gangue or carbon, 0.5 to 5% of binder and 0.2 to 2% of surfactant. The light ceramsite sand is prepared by kneading, granulating and roasting processes. According to the invention, the industrial sand making solid waste wet materials are effectively recycled, resource waste is reduced, meanwhile, the problems of quantitative treatment, environment pollution, stacking and burying and the like of the industrial solid waste are effectively solved, the problem that natural ore is excessively mined is solved, resource utilization is achieved, waste is turned into wealth, and the production cost of ceramsite sand is reduced.
本发明公开了一种轻质陶粒砂及其制备方法，包括以下重量百分比的组分：工业制砂固废湿料80‑95%，硫酸钠或氧化镁3‑10%，煤矸石或碳1‑5%，粘结剂0.5‑5%，表面活性剂0.2‑2%。通过捏合、制粒及焙烧工艺制得轻质陶粒砂。本发明通过将工业制砂固废湿料有效的回收利用，在减少资源浪费的同时，还有效地解决了工业固废的量化处理、污染环境、堆埋等问题，弥补天然矿石开采过量的问题，实现资源化的利用，变废为宝，降低陶粒砂的生产成本。
