The process consists of injecting quick lime in an agitated slaking tank maintaining high concentration. The exothermic reaction by mixing quick lime with water creates heat and steam. A dust scrubber located on top of the tank removes this excess of steam and creates proper tank aeration.
Rich or Fat Lime : This lime is produced by the calcination of nearly purest form of limestone, chalk, marble, etc. Its color is perfectly white. It should have impurities of clay less than 5 percent. It slakes vigorously and volume becomes 2 to 3 times. Since the slaking process is vigorous for this lime, care must be taken to avoid any fire ...
This method is often referred to as the slaking of lime. Quicklime is an oxide that, when bright into contact with an acid, forms salts. Quicklime is known to crystallise in a cubic crystal lattice.

impact the slaking process, although are generally less detrimental to the process. The third factor to watch in slaking water chemistry is hardness, which can result in ... The final factor to impact lime slaking is steam control. The slaking reaction will generate significant amounts of steam, which needs to be removed from the slaker
Superior Paste-Slaking Process Utilizing a 2:1 water-to-lime ratio, the A-758 unit slakes lime as paste which provides a number of benefits over the more traditional 4:1 water-to-lime or slurry slaking process. This includes less power, faster slaking, a smaller footprint and, most importantly, a more reactive lime slurry solution. usage. Saves ...
A video to demonstrate the principles of the Techmatic lime slaking and dosing process.
The slaking of quicklime to produce a hydrated lime slurry occurs in a broad range of industries. In this article, we explain the six fundamental factors that impact the slaking …
Lime Slaking is the process of mixing quicklime (calcium oxide, CaO) with water to form hydrated lime (calcium hydroxide CaOH 2), using excess water to produce a slurry. The reaction of quicklime and water is exothermic and will produce 491 BTUs per pound of CaO and form 1.32 pounds of calcium hydroxide. For most
Lime is one of the most common and economical chemicals used in the water and wastewater treatment process. The cost of commercial bulk hydrated lime or prepared lime slurry solutions, however, becomes prohibitive for installations requiring a continuous, high volume supply, typically greater than 45 kgslhr (100 lbs/hr). ... efficient slaking ...
11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be
LIME SLAKING 101 The slaking of quicklime to produce a hydrated lime slurry occurs in a broad range of industries. In this article, we explain the six fundamental factors that ... hydrated lime slurry in a process known as slaking—the focus of this white paper.

Lime slaking is a process where quicklime, CaO, is converted to hydrated lime slurry, Ca(OH)2 by mixing it with water. It is an exothermic process and thus generates heat and steam. Slaked i.e. hydrated lime is used in several applications like in pH control and neutralization, industrial manufacturing processes in pulp&paper and in mining ...
Lime slurry from hydrated lime powder is easily prepared by mixing the dry powder in water. Quicklime on the other hand generates a lot of heat when it is mixed with water, in a process known as slaking, to produce slaked lime slurry. ProProcess designs cater for hydrated lime slurrying or slaking of quicklime in specialised lime slakers.
