Principle of Dry Type Three Stage Lime Slaker
Principle of dry type three-stage lime slaker:
1. it can control the hydration reaction between Cao slakers for 15-20 hours, and make Cao full hydration
2. the unique design of good heat preservation performance of hydration apparatus makes the internal conversion of the heat slaker in the Cao reaction process be improved by 3-5 hours to 60 degrees, which is conducive to the filling and digestion of Cao
3. feed process control: advantages of feeding materials required by screw propeller into the three stage lime hydrator: prevent Cao from contacting with water to produce hot steam dust and flow back into the screw feeding scale to affect the accuracy of signal transmission
4. three grade water hydration: through the general water distribution system, Cao is filled and pre-hydrated and hydrated by Cao and reasonable water ratio to enter the second stage hydration reaction process. The second stage hydration has reached a good hydration speed. The second stage hydration enters the third stage lime slaker, and the Cao has entered the semi-dry state, and finally, the whole lime hydration process from Cao to fluffy dry powder is about 15-20 hours after the third stage lime hydration process.
