LIME SLAKING SYSTEMS | Bulk Handling Technologies
LIME SLAKING. Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 -> Ca (OH)2) by mixing with water. Lime slaking is an exothermic process which generates heat and creates steam. Slaked or hydrated lime is often used in mining and process industries for raising pH or neutralising acidic solutions.

Lime and its Production
There are three main ways of slaking the Quicklime: in an excess of water to produce a putty; in a shortfall of water to produce a powder - hydrated or bag lime; in damp sand to produce a hot mix. Lime carbonation. Lime sets by absorbing water soluble Carbon Dioxide from the air. This process is called carbonation.

How does a Lime Kiln Work
To produce quicklime in lime kilns, there are mainly three processes. The first stage is preheating. The second stage is calcining. And the third stage is cooling. In the preheating stage. The feed limestone is preheated by the exhaust hot air from the lime kiln, so that partially of the limestone will be calcined.

LIME SLAKING 101
slaking temperatures can reduce the total time required to complete the slaking reaction as illustrated in Figure 1. Slaking temperature itself is a function of the water-to-lime ratio, the quality of the quicklime, heat transfer efficiency within the slaker, and the slaking water temperature—the second fundamental factor of lime slaking.
