This is where MERRICK's experience in the design and manufacture of lime feeding and lime slaking systems comes into play. For economic reasons, on-site conversion of CaO, calcium oxide (also called quicklime or pebble lime) is preferred to purchasing hydrated lime. Quicklime requires only about 75% as much chemical by weight to obtain the ...

Slaked Lime
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.

Lime Slaker
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 ...

Lime Slaker Heating | Direct Steam Injection Heating
A number of industries use hydrated lime addition for their processes. Hydrated lime (or calcium hydroxide, or slaked lime) is usually a dry powder resulting from the controlled slaking of quicklime with water. The exothermic or released heat of reaction is captured and used to evaporate the excess slaking water.

A REVIEW OF LIME SLAKERS
Typically, in a Paste slaker, the water to lime ratio is about 2.5 to 1. As paste exits the slaker, it is diluted to allow heavier particles to settle to the bottom of the grit chamber, so it can be removed from the grit chamber via grit elevator drag chain. The final slurry solid concentration after grit removal is 15% to 18% -
