Lime slaking is an indispensable key process in industrial production, widely used in water treatment, flue gas desulfurization, chemical manufacturing, and papermaking industries. By reacting quicklime (CaO) with water to produce hydrated lime slurry (Ca(OH)₂), lime slaking provides essential support for numerous industrial processes. This article delves into the technical aspects and applications of lime slaking and introduces how Cronus Industrial delivers exceptional solutions through high-efficiency equipment.

Lime slaking refers to the chemical reaction between quicklime (CaO) and water (H₂O) to produce hydrated lime slurry (Ca(OH)₂). This process releases a significant amount of heat and is accompanied by volume expansion. The chemical reaction is as follows:

CaO + H₂O → Ca(OH)₂ + Heat

The efficiency and quality of lime slaking directly impact the effectiveness of downstream processes, making the choice of efficient and reliable slaking equipment crucial.

1. Temperature Control
   Lime slaking is an exothermic reaction, and the temperature is usually maintained between 80-90°C. Temperatures that are too high or too low can affect reaction efficiency and product quality.
2. Retention Time
   The hydrated lime slurry needs sufficient retention time in the equipment to further enhance its activity and concentration.
3. Precise Lime-to-Water Ratio
   The ratio of lime to water directly affects slaking efficiency and the quality of the hydrated lime slurry. Typically, the water amount is slightly higher than the stoichiometric ratio to ensure complete reaction.
4. Mixing and Agitation
   Efficient mixing mechanisms ensure thorough contact between lime and water, preventing clumping and undigested lime residues.

1. Flue Gas Desulfurization (FGD)
   In coal-fired power plants and industrial boilers, lime slurry is used to remove sulfur dioxide from flue gases, reducing air pollution.
2. Chemical Production
   Lime slurry is a key raw material for producing calcium carbonate, calcium hydroxide, and other chemical products.
3. Water Treatment
   Lime slurry is used to adjust water pH, soften water, and remove heavy metals, ensuring water safety and compliance with discharge standards.
4. Construction and Metallurgy
   Lime slurry is also widely used in construction materials and metallurgical processes.
5. Papermaking Industry
   Lime slurry is used as a bleaching agent and filler, improving paper quality and production efficiency.
