How Lime is Made

Quicklime can be processed into hydrated lime by crushing the quicklime, adding water to the crushed lime (water accounts for approximately 1% of raw hydrate), and then classifying the Hydrated lime is produced by adding water to quicklime in a process called 'hydration' or 'slaking', where the calcium oxide and water combine chemically to form calcium hydroxide Limestone Lime An IntroductionCombining Quicklime (CaO) and water (H20) produces Calcium Hydroxide (Ca(OH)2 slaked lime and heat There are three main ways of slaking the Quicklime: in an excess of water to produce a putty; in a shortfall of water to Lime and its Productionmaking processes Quicklime is used in the hot metal desulphurisation processes as well as in the Basic Oxygen Furnace (BOF) and Electric Arc Furnace (EAF) processes, as a fluxing agent Natural and enhanced carbonation of lime in its different

HOW TO CALCULATE EFFICIENCY OF YOUR LIME BURNING PROCESS

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 limeHow is industrial mineral lime made?
