Preparation method of cementing material based on phosphate tailings
The invention relates to the technical field of solid waste recycling, and discloses a preparation method of a cementing material based on phosphate tailings. The phosphorus tailings are dried at the temperature of 105 DEG C, and the drying time is 2-3 hours; s2, crushing: after the phosphate tailings are dried, sieving the dried phosphate tailings with a 200-mesh sieve or crushing the phosphate tailings until the particle size is less than 0.074 mm to obtain fine powder; and S3, calcining: after the crushing is completed, putting the obtained fine powder into a high-temperature calcining kiln, and calcining. According to the preparation method of the cementing material based on the phosphate tailings, the composite magnesium-calcium cement is invented according to the chemical components of the phosphate tailings and by integrating the characteristics of calcium cement and magnesium cement, beneficial components of waste are utilized, a small amount of cost is input, and the industrial innovation effect is achieved. The product has the advantages of low cost, excellent performance, low energy consumption, convenience in production and the like, and can be widely applied to the field of engineering construction.
本发明涉及固废再利用技术领域，且公开了一种基于磷尾矿的胶凝材料的制备方法，包括以下步骤；S1、烘干：使用105℃温度对磷尾矿进行烘干，烘干时间为2‑3小时；S2、破碎：磷尾矿烘干结束后，然后将烘干后的磷尾矿过200目筛或破碎至0.074mm以下，得到细粉料；S3、煅烧：破碎完成后，将得到的细粉料置于高温煅烧窑中进行烧制。该种基于磷尾矿的胶凝材料的制备方法，根据磷尾矿的化学成分，综合钙质水泥和镁质水泥的特征，发明的一种复合镁钙水泥，利用了废弃物的有益成分，投入小量的成本，实现了行业革新的效果。产品具有成本低、性能优良、能耗低、生产便捷等优点，且可广泛应用于工程建设领域。
