Preparation method of liquid calcium hydroxide
The invention discloses a preparation method of liquid calcium hydroxide. The preparation method of the liquid calcium hydroxide comprises the following steps of: calcining, impurity removal, crushing, digestion and separation. The digestion step is divided into two steps, the first step is common coarse digestion, and the second step is grinding digestion which can be improved through grinding digestion. The preparation method further comprises the sixth step. According to the sixth step, ground and digested calcium hydroxide slurry is filtered through a filter screen, so that impurities canbe removed, and then the slurry is sent into a centrifugal separator; the rotating speed of the centrifugal machine is controlled; and the slurry is separated into clear liquid and liquid calcium hydroxide with the corresponding concentration. By means of the above method, particles of liquid calcium hydroxide can be ground to the micron order, deep digestion time is obviously shortened, impurities in a finished product are reduced, and the product quality and production efficiency are improved.
本发明公开了一种液态氢氧化钙的制备方法，所述液态氢氧化钙的制备方法包括以下步骤：煅烧、除杂、破碎、消化和分离步骤，其中消化步骤分为两步，第一步为普通的粗消化，第二步为研磨消化，通过研磨消化可以提高，步骤六、将经研磨消化后的氢氧化钙浆液经滤网过滤除杂后送入离心分离机中，控制离心机转速，将浆液分离成清液和相应浓度的液态氢氧化钙。通过上述方式，本发明能够将液态氢氧化钙的颗粒研磨到微米级，明显降低深度消化的时间，减少成品中的杂质，提高产品质量和生产效率。
