In digestion, there is digestion reaction in lime in digester with hot water（It is not less than 80 DEG C）, quick lime and hot water ratio are 1:0.3～
0.6, by three-level auger dynamic digestion（30min～60min）Mixing, at high operating temperatures, is progressively digested；
3rd, it is homogenized：
The material of three-level dynamic digestion enters homogenizing auger in digester（Total length is not less than 20 meters）, stirring by auger
Mix, be homogenized（30min～60min）, make not digest completely calcium oxide and be deposited in the bottom of homogenizing auger and digest again, after digestion
Material homogenizing bin is entered by elevator, in lifting process, using pulse dust removal most vapor and temperature are eliminated,
The material for making digestion good has good gas porosity and fineness, be conducive to below select powder and processing；
4th, static digestion：
Homogenizing auger material out, by elevator static digestion more than 2h is promoted in homogenizing bin；
5th, roughly select and get the raw materials ready：
After the static digestion of more than 2h, material conveying auger to elevator, by drum sieve by insufficiently burnt lime
Stone is sifted out and discharged, and then material is delivered to into storehouse of getting the raw materials ready by auger；
6th, process：
The material in storehouse of getting the raw materials ready enters the ultra-fine grey calcium machine of alloy through charging auger, and sierozem power after processing is using grey calcium machine inside shape
Into high pressure draught be delivered to product storehouse preserve.
Further, vapor retracting device is provided with described step two and step 3, condensed water can be circulated
Utilize.
Further, slag-discharging device is equipped with described step five and step 6, by the thick thing impurity row such as waste residue, cinder
Go out, can be with improve product quality and content.
The present invention has the beneficial effect that：The preparation method of a kind of building coating level sierozem power of the present invention, by the work
Sierozem power made by skill can reach building coating level sierozem power requirement, and the present invention has the advantages of processing is simple, and setting is reasonable.
