The most common method for the preparation of slaked lime is via the reaction between calcium oxide (also known as quicklime) and water. When combined with water, a relatively small proportion of the quicklime dissolves, resulting in the formation of a solution known as limewater. The remainder of the quicklime remains in a suspension, which is ...

Fossil Free drives carbon negativity. Lime mud reburning in the Kraft process used in pulp/paper/board production is a major source to CO2emissions. The lime kiln is often the last big consumer of fossil fuels in the mill. In Sweden many lime kilns have been converted to biofuels, which instead means that great amounts of biomass are consumed.

Standard Horizontal Ball Mills are sometimes used for lime slaking. Considering that Ball Mills are designed for grinding, and the slaking process is simply a chemical process, it is obvious that the use of a Ball Mill for slaking is not the best choice of equipment in most cases. However, there are a few cases where the use of a Ball Mill ...

The largest single use of lime is in steel manufacturing, where it serves as a flux for removing impurities (silica, phosphorus, and sulphur) during refining of steel. The fastest growing use of lime is in environmental applications, where lime is used for treatment of flue gases, wastewater, solid waste, and drinking water.

In pulp and paper plants, lime can be used for many other purposes. They include water treatment, pH neutralisation, and flue gas cleaning, and so on. The reactivity of lime and CaO content must be the best possible, in order to facilitate a smooth slaking process and the best yield in sodium hydroxide recovery.

Care must be taken during the slaking of this lime, as any excess addition of water will cause the lime to harden. Depending on the percentage of clay present, it is further classified into feebly, moderately and eminently hydraulic lime. Poor Lime : This lime is also known as lean lime or impure lime. It contains clay impurities more than 30%.

Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 > Ca (OH)2) by mixing with water. Lime slaking is an exothermic process which generates heat and creates steam. Slaked or hydrated lime is often used in mining and process industries for raising pH or neutralising acidic solutions.
