Burning (calcination) of these minerals in a lime kiln converts them into the highly caustic material burnt lime, unslaked lime or quicklime (calcium oxide) and, through subsequent addition of water, into the less caustic (but still strongly alkaline) slaked lime or hydrated lime (calcium hydroxide, Ca(OH) 2), the process of which is called ...

The slaked lime slurry flows into an integral grit chamber which permits suspended grit to settle out. The design of the grit chamber permits automatic grit removal without interruption of slaker operation. After grit separation and final dilution, the lime slurry is discharged by gravity flow to process.

A lime slaking system for hydration of lime and removal of unwanted grit, particularly for formation of reactive slaked lime to be used in SO 2 scrubbing of effluent gases, comprising a series of slaking vessels (10,12) for reacting CaO and water while agitating the reactants, a dilution mix tank (14) receiving a viscous slaked lime slurry from the vessels, diluent for the dilution tank ...
Although lime is used throughout our industry, we see many misapplications and misunderstandings of this technology. We have seen the wrong type of silos used as well as the wrong size silos. Slaking is a major problem for some plants because they use the wrong water and lime products.
After approximately 5 minutes, the completely slaked lime paste flows over a weir into the dilution compartment. Here water nozzles direct a cut-off spray to dilute the paste into a lime slurry at an approximate 4:1 concentration. This also releases the grit from the lime paste so that it can be removed.

Lime Slaking. If lime slaking efficiency is removed from the economic analysis, the higher cost and reagent consumption of hydrated lime still justifies the installation of a slaker. The proportion of pebble lime to hydrated lime was varied to find the breakeven point between the two slaker systems.
TREATMENT OF LIME SLAKER GRIT AND GREEN LIQUOR DREGS – CURRENT PRACTICE ... This increase in pH was presumably due to the un-slaked lime encapsulated in the 'grit.
lime slurry solutions, however, becomes prohibitive for installations requiring a continuous, high volume supply, typically greater than 45 kgs/hr (100 lbs/hr). To help alleviate this cost, on-site slaking or hydration is the ideal solution. The Series A-758 lime slaker provides for reliable, efficient slaking of various grades of quicklime (CaO)

rate of lime and the amount of available lime theoretically available for slaking. The percentage grit does not seem to be as sensitive a measure to gauge reactivity and is therefore not recommended for use to distinguish between reactivity of various limes. Commercial lime slakers in industry normally operate by using 3 to 4 parts of water for ...
Hydrated lime, also known as calcium hydroxide {Ca(OH) 2}, is a refined mineral product.Calcium oxide is stoichiometrically reacted with water in a controlled process to form a hydrated lime product that has the consistency of a fine white powder containing less than 1% residual moisture.

LIME SLAKING The term lime slaking applies to the combination of varying proportions of water and quicklime in order to produce milk-of-lime, a lime slurry or a viscous lime paste. Chemically, the slaking process is an exothermic reaction that releases appreciable heat and forms hydroxides.
The slaked lime slurry flows into an integral grit chamber which permits suspended grit to settle out. The design of the grit chamber permits automatic grit removal without interruption of slaker operation. After grit separation and final dilution, the lime slurry is discharged by gravity flow to process.
