我厂锂辉石一石灰石烧结法生产氢氧化锂工艺技术,经十几年的努力,已有很大提高。在生产工艺中摸索和创造了适合我国国情的一套工艺方法和技术条件。如在烧成方面,由单一重量比配料改为两段配料,准确控制生料浆中氧化钙,稳定了入窑料浆成份;在烧成技术操作方面,使熟料质量大幅度提高;在浸出方面,选择了合适的技术条件,并在洗涤流程及所用设备上进行了相应改进;在蒸发精制方面,采取了澄清除杂,分步蒸发,洗涤精制,压风吹搅等一系列简 I plant spodumene limestone sintering process of production of lithium hydroxide technology, after more than 10 years of hard work, has been greatly improved. In the production process to explore and create a suit of our national conditions a set of process methods and technical conditions. As in the firing, from a single weight ratio of ingredients to two batches of ingredients, accurate control of calcium oxide raw slurry, stabilized into the kiln slurry ingredients; in the firing of technical operations, so that clinker quality greatly improved in the Leaching, the choice of the appropriate technical conditions, and in the washing process and the equipment used for the corresponding improvement; in the evaporation purification, to take a clear impurity removal, step evaporation, washing refining, air blowing and blowing a series of Jane
