· 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 particle size.

· SLAKING OF LIME. Slaking of lime is a process of adding excess water for hydration of Calcium oxide (CaO). This results in the formation of hydrated oxide Ca(OH) 2.which is slurry in appearance.When lime cannot absorb any further quantity of water, the process is said to be completed.
Lime Slaking Incorrect slaking temperature and water to lime ratios in the slaking operation can result in poor quality hydrated lime. If the slaker is not operated under negative pressure, steam and moisture travels back into the feeder and lime bin and causes "caking" problems. Instrumentation panels located on or adjacent to the slaker are ...

Key Factors to Lime Slurry Usage in Water Treatment Processes. Aug 01, 2017· The Lime used in the water treatment industry is referred to as either quicklime (CaO) or hydrated lime (Ca(OH)², which is hydrated in a slaking process before it's used for chemical coagulation, precipitation, pH adjustment and chemical stabilization of sludge.
· Slaked lime, which is the common name for calcium hydroxide, is a chemical compound whose formula can be represented as Ca (OH) 2. Under standard conditions for temperature and pressure, slaked lime is known to exist as a white, powdery substance. Alternately, this compound can also exist in the form of colourless crystals at STP.
Slaking is an exothermic process meaning the heat is produced as the quicklime reacts with water and this heat must be managed by carefully controlling the ratios of water and lime and any resulting steam and dust must be captured for safety and housekeeping concerns.
