IntroductionCalcined Lime or Quicklime (or calcium oxide, or burnt lime), is obtained by calcining(controlled heating - time and temperature) limestone at temperatures above 900°C. This highly reactive product is essential to many industrial processes. We are manufacturers and suppliers of Quicklime or Calcined Lime from India.
Chemical formula : CaO
Available products (usually defined by size gradation) : pebble, ground, milled, fluidized lime, dust-free lime (Proviacal® ), etc.
Process The production of high calcium quicklime (calcium oxide) requires a large amount of heat, which is generated in the kiln environment. The quarried and sized high calcium limestone travels through a rotary kiln and is subjected to these high temperatures where the calcium carbonate begins to dissociate with the resultant formation of calcium oxide. The minimum temperature for the dissociation of calcium carbonate is 1648oF (898oC). For practical production purposes, however, the kiln temperature range is from an initial temperture of about 1750oF (954oC) to a final temperature of about 1950oF (1066oC). These temperatures can vary dependent upon the nature of the limestone being calcined.
