Coal gangue ceramsite and preparation method thereof
The invention discloses coal gangue ceramsite, which is prepared from the following raw materials in percentage by weight: 75 to 95 percent of coal gangue, 5 to 12 percent of fired clay, 3 to 9 percent of a sintering aid, 15 to 25 percent of quartz tail mud, 1 to 5 percent of a forming agent and 2 to 8 percent of graphite powder. According to the coal gangue ceramsite and the preparation method thereof provided by the invention, the graphite powder is added in the ceramsite preparation process and calcined at the same time, so that the overall strength of the ceramsite is effectively improved,and meanwhile, the chemical stability of the ceramsite is also improved.
本发明公开了一种煤矸石陶粒，所述煤矸石陶粒原材料按重量百分比配比为：煤矸石75‑95％，烧制粘土5‑12％，烧结助剂3‑9％，石英尾泥15‑25％，成型剂1‑5％，石墨粉2‑8％。本发明提供的一种煤矸石陶粒及其制备方法在陶粒制备过程中加入石墨粉同时煅烧，有效提升陶粒的整体强度，同时也提升了陶粒的化学稳定性。
