1. Application areas and key functions
Multi-stage dry power(burnt lime power) hydrator is widely used in environmental desulfurization, semi-dry desulfurization, lime finishing, fine chemical and other industries. Using our three-stage dry power hydrator, burnt lime will be hydrated into a fluffy powder because the hierarchical & reasonable water distribution and multi-channel process of this hydrator. The outcome also can be a specific ratio of  lime cream.

2. Principles and performance
Our advantages and principles of three-stage dry power hydrator as below:
It will control the reaction time and fully hydrate the CaO by only 15-20 minutes.
Hydrator has good heat-insulating property. The unique design makes a lot of heat generated in the reaction of CaO to be converted inside and reused. It will raise the inner temperature to 60 degrees by only 3-5 minutes and make the CaO to be fully hydrated.
Feeding process control: Sending the needed materials into the first-stage reaction cabin through the screw feeder.
Advantages: There are lots of hot steam and dust when CaO contact with water. This feeding way will provent them flowing back the screw feeding counter, so that will not affect the accuracy of sensor.
d) Three-stage hydrate reaction with water distribution
The hierarchical & scientific distribution of water can make the CaO to be fully pre-hydrated. Afer contacting with reasonable water in the first stage reaction cabin, then enter into the second one. This process is the best reaction time of CaO. When entering into the third one, hydrated CaO is semi-dry state. The whole three stages finally make the CaO completely become the fluffy powder. And the entire reaction process needs about 15-20 minutes.
3. Equipment superiorities
This device, according to environmental requirements, could collocate with dust removal device which will solve the problem of the steam & dust pollution produced during hydration of quicklime. At the same time this device also can be matched with the follow-up process equipments, such as lime pulping machine, slurry-residue separation machine, filters etc.. So it can produce the high purity lime emulsion to meet the needs of concentration.
4. Parameter requirements
Because our Three-stage dry power hydrator is non-standard equipment and should be customized according your denamd. So please help to provide the following parameters:
  Application and process status for multi-stage dry power hydrator
  Lime particle size, purity and degree of activity
  Lime feeding amount per hour
  If need to match dust removal device
  Water control of the lime and other requirements
