Industrial lime slaking is a complex process and is difficult to model. There are several reasons for this the complexity. Lime slaking is a heterogeIleous reaction between a solid phase (lime) and a liquid phase (water) and furthermore, lime is a natural product where the lime partides vary in Hize and in reactivity.
2.2. Grande Acqua (Z3) In this second method, a pit was dug in the ground, roughly 1.2 × 0.6 m 2 and 1 m deep, which was filled up to its half with burned stones form the lime kiln. Approximately 200 l of water were poured into the hole (see Fig. 1 c). A few minutes after the entering in contact with the lime the water began to boil and, 400 …
FEATURES 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 ...
The lime remained in the form of powder during the whole slaking process. The evolution of quicklime to slaked lime was qualitatively monitored by X-ray diffraction at different time intervals: immediately after slaking and after 3, 5 and 7 days.

Limestone, quicklime and slaked lime. This page looks at the origin and uses of limestone, and its conversion into quicklime, CaO, and slaked lime, Ca(OH) 2. Limestone and marble. Chemically, limestone is calcium carbonate. It is a sedimentary rock formed from the shells and skeletons of marine creatures which fell to the bottom of ancient seas ...
Slaking has been identified as a cause of rock-controlled landforms (differential erosion landforms) such as cuestas and hoodoos. The significant papers by Suzuki et al. (1970, 1972) and Takahashi (1975) attributed the differential erosion of wave-cut benches in the intertidal zone along several coasts in Japan (Figure 5) to the difference in swelling …

Key factors using lime slurry for water treatment processes such as chemical coagulation, precipitation, pH adjustment and chemical stabilization of sludge.
Care must be taken during the slaking of this lime, as any excess addition of water will cause the lime to harden. Depending on the percentage of clay present, it is further classified into feebly, moderately and eminently hydraulic lime. Poor Lime : This lime is also known as lean lime or impure lime. It contains clay impurities more than 30%.
