Lime Slaker: Revolutionizing Powder Processing with Unmatched Efficiency and Precision

In industries such as chemical engineering, metallurgy, environmental protection, and water treatment, lime (quicklime, CaO) is an essential chemical raw material widely used for neutralizing acidic substances, adjusting pH levels, and purifying water quality. However, before use, quicklime needs to undergo a slaking process to convert it into hydrated lime (calcium hydroxide, Ca(OH)₂), and the core equipment for this process is the Lime Slaker. Today, we will delve into the working principles, application scenarios, and how to choose the right lime slaker.

A lime slaker is a specialized device used to react quicklime (CaO) with water (H₂O) to produce hydrated lime (Ca(OH)₂). Its core principle involves controlling the water-to-lime ratio, reaction temperature, and mixing speed to ensure a thorough and efficient reaction. Below are the main steps in the lime slaker’s operation:

1. Feeding: Quicklime powder or granules are fed into the slaker’s reaction chamber.
2. Water Mixing: An appropriate amount of water is added to the reaction chamber based on the set water-to-lime ratio.
3. Mixing and Reaction: Through mechanical stirring or high-speed rotation, the lime and water are fully mixed, triggering a chemical reaction to produce hydrated lime slurry.
4. Discharge: After the reaction is complete, the hydrated lime slurry is discharged through the outlet and can be directly used in subsequent processes.

Throughout the process, the lime slaker ensures the quality and efficiency of the hydrated lime by precisely controlling the reaction conditions.
