  • 2-3 Lime Kiln & Effects on Operations

    The composition of lime mud varies from mill to mill depending on many factors: species, the impurities in the make-up lime and refractory bricks used in the kiln, the efficiencies of slakers, causticizers, clarifiers and mud washers, and the burning conditions in the kiln. On a dry basis, lime mud typically contains about 95 wt% CaCO3


    (e.g. 1000 C in a lime kiln) to 'drive off' carbon dioxide, CO 2. The equation for this process, with the approximate molecular weights, is: 100 CaCO 3 + Heat <==> 56 CaO + 44 CO 2 Continuing the approximation for hydration gives: 56 CaO + 18 H 2O <==> 74 Ca(OH) 2 + Heat So, in simple terms, if the process were carried out with 1 tonne of

  • What is the chemical formula of lime, quicklime and slaked

    May 28, 2018· Answered May 28, 2018. The chemical formula for lime is CaCO3 . When lime is dissociated then it produces quick lime and carbon dioxide . CaCO3 → CaO +CO2. So, the chemical formula of quick lime is CaO. When quick lime reacts with water it produces lime water or slaked lime . CaO + H2O → Ca (OH)2.

  • Lime (material) Wikipedia

    Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
