3.2 This Standard specifies requirements and procedures for a certification system that shall apply to all Suppliers providing hydrated lime. These provisions apply to the plant manufacturing the hydrated lime. These provisions apply to the Contractor, after delivery of the hydrated lime , for use on CDOT projects.
The process is called “hydration” and should be differentiated from “slaking” which involves the production of a dispersion of calcium hydroxide in water. However, the expression “slaked lime” is employed as a generic term for hydrated lime, milk of lime and lime putty. A calculable 10 to 15% of the quicklime produced in developed

The hydrated lime can is with stoichiometric volumes of water as required to fully hydrate the quicklime and water mixture as well as with volumes beyond the calculated stoichiometry with some potential for remaining water left after the process without the potential for lime putty or a wet hydrate as the result.

ever hydrated lime is required.The quantity of hydrated lime that is needed has a critical bearing on profitability. The system is also suitable for the particular requirements of waste-to-energy plants. The dosing unit delivers the quicklime (CaO) into the pre-hydrator, where water (H2O) is added by means of a nozzle and mixed with the quicklime.
Lime production is really not a matter of calcination only. A modern plant must have preheaters, dust collection equipment, ample storage to provide for kiln downtown and operators who are skilled in the art of lime-burning.

In ponds that are drained often, meet the lime requirement based upon initial soil analysis and subsequently apply lime annually at 25% of the initial lime requirement (Boyd and Tucker, 1998). Boyd (1997) cautions against overapplication of lime, especially burnt (CaO) or hydrated (Ca(OH) 2 ) lime, because at the resulting high pH values ammonia toxicity becomes a problem.

Hydrated lime requirements definitely exceed the vast tonnage of quick lime required in dry, thermal processes such as sintering, smelting, and fluxing etc. Hydrated lime is used for neutralization, coagulation, canticization, dehydration, hydrolyzation and absrption.

To produce hydrated lime, calcitic lime is crushed to a powder and heated in a kiln to a specific temperature and for a specific duration. After the heating process, it is known as quicklime, to which water is added and then processed further.

The specific surface of hydrated lime is mostly affected by the type of limestone used and its calcination and slaking processes . In industry, slurry detention, paste, ball mil and batch slackers produce hydrated lime without the need of the grinding process [19,20]. The typical specific surface of hydrated lime ranges from 8 to 58 m 2 /g.

production costs to a minimum. In the majority of cases, a very major production cost will be the fuel used. Thus, the efficiency of the burning process (as opposed to the whole process of production which will involve labour costs etc.) is judged by how much fuel it takes to produce a quantity of quicklime. For instance, a lime-

Hydrated Lime Manufacturing Process Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing.
Hydrated lime additions have also improved the digestibility of wheat straw for sheep (Djajanegara, 1985). 90 In addition to livestock uses, hydrated lime has a long history of use in crop production as a plant disease 91 control agent, and is an essential component of lime sulfur (i.e., hydrated lime, elemental sulfur and water)

Hydrated Lime Manufacturing Process. The hydrated lime powder manufactured by us is considered to be the best chemical reagent and so it is widely used in various specialty chemical applications. Here we take a look at the main production process of hydrated lime. The heart of a lime plant is the kiln.
Hydrated lime is the type of lime mostwidely used as a component in mortars and renders. Hydratedlime , and quicklime (see below) are commonly referred to as''air lime '' products. This is because they do not react with the water in the mix to form a'' set ''.
