High-strength ceramsite based on demagging boron mud-oil shale semicoke and preparation method thereof
The invention relates to high-strength ceramsite based on demagging boron mud- oil shale semicoke and a preparation method thereof. The high-strength ceramsite comprises the following raw material components in percentage by weight: 45-50% of demagging boron mud, 45-50% of oil shale semicoke and 3-5% of sodium silicate. The stacking density is 830-890kg/m<3>, and the cylinder compressive strengthis 9-13MPa. The preparation method comprises the following steps of: (1) mixing the demagging boron mud with the oil shale semicoke; (2) grinding and drying the mixture to obtain powder; (3) sieving the powder with a 200-mesh sieve to obtain a pretreated material; (4) mixing the pretreated material with sodium silicate, and adding the mixture into a granulator to prepare master batch; and (5) drying the master batch at 105-120 DEG C, preheating the master batch at 500-550 DEG C, roasting the master batch at 1050-1100 DEG C for 20-30 minutes, and cooling along with the furnace. According to themethod, the problem of stockpiling treatment of the boron mud and the oil shale semicoke is solved, and the harm to the environment is reduced; and the ceramsite with excellent performance can be prepared, a large amount of clay resources can be saved, and the production cost is reduced.
一种基于脱镁硼泥‑油页岩半焦的高强陶粒及其制备方法，原料成分按重量百分比为：脱镁硼泥45～50％，油页岩半焦45～50％，硅酸钠3～5％；其堆积密度830～890kg/m3，筒压强度9～13MPa；制备方法为：1)将脱镁硼泥和油页岩半焦混合；(2)磨矿烘干制成粉料；(3)粉料过200目筛获得预处理物料；(4)将预处理物料与硅酸钠混合，加入用造粒机制成母粒；(5)在105～120℃干燥，在500～550℃预热，在1050～1100℃焙烧20～30min，随炉冷却。本发明的方法解决了硼泥和油页岩半焦的堆存处理难题，减轻了对环境的危害；可以制备出性能优异的陶粒，还能够节省大量粘土资源，降低生产成本。
