the production process of limestone

The limestone’s temperature rises to about 900℃ heated bykiln flue gasof 1150℃, about 30% of them are decomposed, and they come into thelime rotary kilnbyhydraulic rod, where the limestone decomposed into CaO and CO2. The decomposed limestone are put intothe cooler,where its temperatures drops to 100℃ and released

    When limestone is subjected to heat, pressure, and chemical activity, the calcite in the rock begins to transform. This is the beginning of the process known as metamorphism. Starting at a microscopic scale, the calcium carbonate in the rock begins to crystallize or recrystallize into fine-grained calcite crystals
