Xingbang Heavy Machinery is a professional manufacturer of mining equipment, especially on limestone processing. We bring in latest technology to produce mining machines like the stone crushers, rotary kiln, shaft kilon and quicklime slaker.

We not only supply the machines, but also supply the service. pre-sale service includes the production line design, location selection; after sales service contents: construction instruction, equipment maintenance, and repair.

Three stage burnt lime hydrator to make precipitated carbonated calcium line as the main machine to slake the quicklime for hydrated lime power/paste and make the light calcium carbonate PCC is the most important machines, so our three stage lime slaker is very popular because it  has following steps, and our advantages are following:

Flowchart:

The crushed and weighed quicklime from the constant weight feeder enters the three-stage lime hydrator where water is mixed with the quicklime in the required proportions to achieve complete hydration. According to different process requirements, it is able to make serous fluid become different sized hydrated lime powder by the air separator.

Principles and advantages of three-stage dry hydrated lime production line

1. Three stage reaction with water distribution

The hierarchical & scientific distribution of water can make the calcium oxide to be fully pre-hydrated. After contacting with reasonable water in the first stage reaction chamber, the mixture enters into the second stage. This process is the best time for hydrating. When entering into the third one, hydrated lime is already semi-dry state. Three stage hydrator can finally make the calcium completely become the fluffy powder. And the entire reaction process just needs 8-15 minutes.

2.Time control

It will control the time of reacting water and calcium oxide, fully hydrating just needs 8-15 minutes.

3 Insulation function

Hydrator has good insulation function. As we all know, temperature may influence the rate of chemical reaction. The unique design makes it possible to reuse the vast heat which generated from the reaction inside the hydrator. It will raise the inner temperature to 60 degrees by only 3-5 minutes and make the calcium oxide to be fully hydrated.

4 Feeding process control

To pour the needed materials into the first-stage reaction chamber, screw feeder plays a extremely vital use for preventing hot steam and dust flowing back into the screw feeder, otherwise that will affect the accuracy of sensor.

5. Remove dust to keep clean and healthy

This device, according to environmental requirements, equipped with our patent dust remove device, will solve the problem of the steam and dust pollution produced during hydrating ,so that ensure the clean of the environment and the health of workers.
