Key Factors to Lime Slurry Usage in Water Treatment Processes

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.

Aug 01, 2017· Slurry viscosity varies dependent on hydration conditions. Viscosity increases at slaking temperatures of 180°F and above. The relationship of viscosity, particle size, and specific surface is not completely researched. In general it is presumed that higher viscosity means smaller particle size of hydrate and greater surface area.
