针对化成法重钙生产过程中熟化库小、熟化期短、产品游离磷酸难控制、物料物性差及系统堵塞严重等问题,提出了在反应过程中添加适量硫酸、混合器优化改造、使用轻烧镁粉(苦土)作中和添加剂等3项措施,降低和稳定了重钙产品游离酸含量,物料物性改善,产品质量提高。 Aiming at the problems such as small ripening bank, short maturation period, difficult control of product free phosphoric acid, poor material properties and serious system blockage in the process of chemical synthesis of heavy calcium, this paper put forward that during the reaction process, adding appropriate amount of sulfuric acid and optimizing the mixer, Magnesium powder (bitter soil) as additive and other three measures to reduce and stabilize the free acid content of TSP product material properties to improve, improve product quality.
