Dead burned magnesia preparation method capable of reducing energy consumption
The invention relates to a dead burned magnesia preparation method capable of reducing energy consumption. The method comprises the following steps: 1) crushing magnesite in a crusher, and sieving; 2)weighing low-sulfur coal and raw ore according to a weight ratio of (30-38): 65; (3) before ignition and furnace starting, laying the low-sulfur coal below a sintering area of a shaft kiln, and thenperforming layered material distribution in a manner that the raw ore and the low-sulfur coal are alternately laid layer by layer on each layer to enter the shaft kiln until reaching a material distribution area; 4) completely combusting the low-sulfur coal below a sintering area, and sintering for 3-4 hours; and 5) cooling and discharging. According to the method, the dead-burned magnesia is produced by adopting the low-sulfur coal, so that the sintering cost for producing the dead-burned magnesia is reduced, the consumption of non-renewable energy sources is reduced, the quality of the produced dead-burned magnesia is greatly enhanced, and the using effect of a derivative product prepared from the dead-burned magnesia is also obviously improved.
本发明涉及一种降低能源消耗的重烧镁砂制备方法，包括以下步骤：1)菱镁矿石在破碎机中破碎，过筛；2)低硫化煤与原矿按照重量比(30‑38)：65称取；3)在点火起炉前，用低硫化煤铺垫竖窑烧结区以下，之后进行分层布料，每层都以原矿和低硫化煤进行交替层层铺垫进入竖窑当中，铺垫到布料区为止；4)待烧结区以下的低硫化煤全部燃烧，烧结3‑4h；5)冷却出料。本发明采用低硫化煤生产重烧镁砂，降低了生产重烧镁砂的烧结成本，减少了对不可再生能源的消耗；产出的重烧镁砂品质得到了极大的增强，其所制造的衍生产品的使用效果也有明显的提高。
