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 quick lime was slaked in two ways: wet slaking and earth slaking. Since the earth slaking technique of lime is not widely spread outside of Gotland, it will be described in detail. 3.1 Wet slaked lime Wet slaking of lime means slaking quicklime with a surplus of water in order to get a lime putty.

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.
