Quicklime Use Reduction In Slakers

alongside the quicklime and incorporated into the slurry.2 The final slaker type is the batch slaker. These slakers are unique in that they do not offer continuous operation. Instead, batch slakers use weigh cells to control the amount of water and/or quicklime added to the tank, which is equipped with a vertical impeller for mixing.

Lime Slakers are machines that convert quicklime (calcium oxide) into a calcium hydroxide slurry for processes requiring pH control and neutralization. Typical applications include water and wastewater treatment and flue gas desulfurization. Read More on Lime Slakers

Calcium Oxide Quicklime. Calcium oxide (chemical formula: CaO), also called quicklime or burnt lime, is a widely used chemical compound in our daily lives formed by ionic bonding between one calcium atom and one oxygen atom. The white or grayish-white crystalline solid, calcium oxide can be produced in large quantities by driving off carbon dioxide from calcium carbonate.

Quicklime requires only about 75% as much chemical by weight to obtain the same results, which translates to 75% less storage capacity, cost of handling and freight. Additionally, quicklime is less dusty and easier to handle. Quicklime is normally metered to the slaker by a gravimetric or volumetric feeder.
