It is well known that slaking conditions influence Ca(OH) 2 particle size. Higher slaking temperatures tend to reduce particle size (Zinck and Aube, 2000) whereas some slaking water impurities, such as sulfates, increase particle size (Potgieter et al., 2003). Slaking technologies, including mixing and milling, also influence slaked lime ...

Precipitated Calcium Carbonate Production | Carmeuse …
The hotter the slaking temperature, the finer the particle size. Combine this with cold carbonation temperatures, and very fine particle sizes are possible. Slaking temperatures for PCC production can approach 195°F (90.6°C). This is hotter than standard slaking temperatures of 175°F to 185°F (79.4°C and 85.0°C) used in other applications.
The kinetics of lime slaking
(3) The slaking rate of pure lime powders depends on the particle size of the powder and the calcination conditions under which the lime was made from calcium carbonate. High calcination temperatures and long calcination times cause coalescence of the lime particles and a reduction of slaking rate.
Decarbonising the lime industry: State-of-the-art
In other words, a common approach in terms of CO 2 emissions reduction may be likely adopted for the lime and cement industry. 3. Quicklime slaking. The hydration of CaO to give Ca(OH) 2 (Equation (2)) mainly involves the electrical input necessary for the handling and mixing of CaO into water (approx. 5–30 kWh consumed …
