However, there are a few cases where ... lime, slaking this type of lime is very difficult in regular slakers if pebble )) )) )))
WO-2013077942-A1 chemical patent summary.
process of adding water to calcium oxide to produce calcium hydroxide is referred to as hydration process or lime slaking. The hydration of CaO, commercially referred to as quick lime, is an exothermic process releasing a great quantity of heat. This hydration process when done with just the right amount of water is called "Dry Hydration."
Uses of Calcium Hydroxide. For whitewashing – Slaked lime is used in whitewashing. It reacts with carbon dioxide slowly and forms a layer of calcium carbonate on the wall which ... For …
The addition of limited quantity of water breaks the lumps of lime.This process is called slaking of lime. This reaction is exothermic and produces hissing sound .It's suspension in water is called as milk of lime.Quick lime slaked with soda gives sodalime.When dry slaked lime is subjected to the action of chlorine,bleaching powder is formed.
Then, a lime slaker is utilized to convert quicklime into slaked or hydrated lime (calcium hydroxide). Problem. The slaking process combines quicklime and water, resulting in an exothermic reaction where heat and steam are released. This heat and steam—which also contains dust particles from the quicklime–must be exhausted from the process ...

2.2. Lime processing 2.2.1. Slaking process of the LCD A metallic tray of 45x30x8 cm was used for slaking 2 kg of the light calcined dolomite. This slaking was conducted in an atmospheric environment at 20ºC and with discontinuous stirring. The initial addition of 3.5 L of water, at ~20ºC, was added to obtain a lime putty. (Fig. 3). 2.2.2.
What is slaking of lime? The process of adding water to calcium oxide to produce calcium hydroxide is referred to as hydration process or lime slaking. ... If excess water is used for hydration, the process is called "Slaking." In this case, the resultant hydrate is in a slurry form.
The slakermust be designed to maintain a constant slakingtemperature between 76.6°C to 82.3°C (170°F to180°F) and produce lime slurry with a constantdensity of 1.15 (20% solids). To achieve this,CaO and water must be added at a constantratio and the temperature of the incoming slakingwater must be controlled to maintain a desiredslaking ...
