Manufacturing Of Fat Lime • The essential raw material for the manufacturing of quick lime is a rock called LIMESTONE CaC03e • Limestone is a sedimentary rock which occurs in nature in good abundance forming hill ranges plateaus Quicklime Quicklime is a caustic white alkali with the chemical name calcium oxide
5 ·For fat lime the percentage of impurities in lime stones should not exceed 5 per cent It is desirable to use comparatively pure carbonate of lime in the manufacturing process of fat lime 2 Calcination of Lime Stones The calcination or burning of lime stones to bright red heat is the next important operation
The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air Lime can either be sold as is or crushed to make hydrated lime Hydrated Lime 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
