The invention discloses a preparation method and a preparation device of calcium hydroxide with high dispersibility and high specific surface area, and the preparation method comprises the following steps: S1, calcining: putting a limestone raw material into a lime kiln for calcining, taking out after calcining, and sorting out a calcined finished product calcium oxide; s2, digestion: mixing a proper amount of water with the calcium oxide obtained in S1 to obtain a mixed solution; s3, stirring: stirring the mixed solution by using a stirrer to obtain calcium hydroxide feed liquid; s4, purification and separation; large-particle calcium hydroxide solids are blocked on the filter screen through the filter screen, the motor drives the fan blades to generate negative pressure, the large-particle calcium hydroxide solids are sucked and automatically put into the grinding box again to be ground, and therefore the grinding degree of calcium hydroxide is increased, the dispersity of calcium hydroxide is improved, and the specific surface area of calcium hydroxide is increased. Meanwhile, the invention also provides a preparation method of calcium hydroxide by using the grinding preparation device, and the product quality can be improved by using the preparation device.
本发明公开了一种高分散性高比表面积氢氧化钙的制备方法及其制备装置，包括：S1、煅烧，将石灰石原料投入石灰窑内进行煅烧，煅烧完成后取出并分拣出煅烧成品氧化钙；S2、消化，取适量的水与S1中得到的氧化钙混合，得到混合溶液；S3、搅拌，使用搅拌器对混合溶液进行搅拌，得到氢氧化钙料液；S4、净化分离；通过过滤网将颗粒较大的氢氧化钙固体阻隔在过滤网上，通过电机带动扇叶产生负压，吸取颗粒较大的氢氧化钙固体，自动化的将其重新投入研磨箱进行研磨，从而加深氢氧化钙的研粉程度，提高氢氧化钙的分散性和比表面积，同时本发明还提供了使用本研磨制备装置的氢氧化钙的制备方法，可以利用制备装置提高产品质量。
