Calcium hydroxide production process capable of accurately controlling moisture

The invention relates to the field of calcium hydroxide production, in particular to the field of IPC C04B28, and more particularly relates to a calcium hydroxide production process capable of accurately controlling moisture. The limestone is treated through the five steps of pretreatment, smashing, pre-digestion, digestion and separation deslagging, calcium hydroxide low in moisture and impurity content and high in purity is obtained, the raw material conversion rate is high, drying is not needed, the production department is easy and convenient to implement, and the method is suitable for batch production. 本发明涉及氢氧化钙生产领域，尤其涉及IPC C04B28领域，更具体地，涉及一种精准控制水分的氢氧化钙生产工艺。通过预处理、粉碎、预消化、消化、分离除渣五步对石灰岩进行处理，得到水分、杂质含量低，纯度高的氢氧化钙，且原料转化率高，无需干燥，生产部洲简便易行，适宜批量生产。
