3-Stage Lime Slaking System Specification

Advanced Designs of 3-Stage Lime Slaker System:

• Controlled Slaking Time: Ability to control the Slaking reaction time of quicklime (CaO) in the Slaker Through various adjustment methods, the lime slaking process can be controlled to last 8 to 15 minutes in the slaker chamber, so that quicklime (CaO) can be fully hydrated.
• Excellent Heat Preservation The unique design allows the large amount of heat generated during the reaction of quicklime to be converted and utilized inside the Lime Slaker, increasing the temperature of the internal quicklime material, which is conducive to the full quicklime slaking.
• Efficient Feeding Process Control The quicklime materials are delivered into the first-level Slaking chamber by screw conveyor. Advantages: It prevents a large amount of hot steam and dust generated at the moment of contact between quicklime CaO and water from flowing back into the screw feeder, affecting the accuracy of the sensing signal.
• 3-stage Water Distribution Slaking: Through the hierarchical scientific water distribution method, quicklime is fully prehydrated. After the first-level Slaking, it enters the second-level slaking chamber for further reaction. The slaking process is sped up with the heat released by CaO in the body. Before the lime material enters the third level slaking, the hydrated CaO has entered a semi-dry state. Finally, after 3-stage slaking, CaO is transformed into fluffy dry powder. The entire slaking process takes about 15 to 20 minutes.
• Dust Removal and Purification The 3-stage slaker is equipped with a dust filter device, which can effectively purify the hot steam and dust generated during slaking process, the steam outlet emission concentration will be controlled below 30 mg/m3.
• Automatic Control and Efficiency PLC Automatic Control Process This 3 stage slaking system can realize PLC automatic control and be adjusted according to the production process, reducing the labor intensity, protecting the health of on-site workers, and improving production efficiency.
• Optional Equipment According to the customer's needs, this slaking system can be equipped with subsequent process equipment, such as lime pulping machine, slag extractor and filter, etc., to prepare high-purity slaked lime emulsion that meets different concentration requirements.

Temperature Control for Lime Slaking

The temperature must reach above 200 degrees to improve hydration efficiency and increase the slaked lime content.

Lime Slaking System Production

Lime Slaking Temperature Control

• To reach this temperature, the air must be well locked at both ends of the slaker chamber, as the natural wind will lower the reaction temperature.
• The slaker chamber should be long, and the pulse dust collector should be installed at its’ tail. Pulling high-temperature steam in the middle of the slaker chamber will lower reaction temperature.
• The slaker chamber cannot be too wide, for the space will be large and the materials will accumulate and get stuck.
•  Low accumulation will also pull away heated steam. Only when hydration temperature is high and the water vapor evaporates quickly can speed up the hydration process (with more water consumed).

3-Stage Quicklime Slaker System Structure:

As the name implies, the 3-stage environmentally friendly quicklime slaker integrates 3 slaking stages. Structurally, it is divided into a first-level (single, double-shaft) slaker chamber, a second-level (single, double-shaft) slaker chamber, The third-level linkage slaker chamber enables the lime to be hydrated evenly, and the hydration rate is greater than or equal to 98%. The double-shaft mixing mode has multiple functions as stirring, crushing and agglomeration, and self-cleaning.

Lime Slaker System Equipment

Lime Slaker Chamber Structure

Its unique blades and stirring method make the quicklime and water mix evenly and react fully; it also plays breaking and pushing role in the lime agglomerates produced during the secondary and primary hydration reactions.
The blades are made of heat-treated high-strength wear-resistant alloy material, it has the function of self-cleaning of bonded materials; This prevents problems such as blade wear or even shaft breakage, extending the service life of the Slaker equipment, effectively avoiding the discharge failure caused by bonded lime.. AGICO can provide users with spare blades for replacement for continuous production.

Quicklime Slaker Chamber Structure:

Quicklime Slaker Chamber consists of u-shaped pipe body, reduction motor, spiral shaft, spiral blade, inlet, outlet, bearing support, coupling, nozzle, etc. Equipped with a unique bag dust filter or wet dust filter to meet the environmental protection emission requirements of 10mg/Nm. The lime slaker system can realize PLC Automatic Control and can be adjusted according to the production process, reducing the labor intensity of on-site workers, protecting the health of on-site workers, and improving production efficiency.
