The limestone’s temperature rises to about 900℃ heated by kiln flue gas of 1150℃, about 30% of them are decomposed, and they come into the lime rotary kiln by hydraulic rod, where the limestone decomposed into CaO and CO2. The decomposed limestone are put into the cooler, where its temperatures drops to 100℃ and released.

Limestone Wikipedia

Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. Dolomite, CaMg N 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare.

Ground Calcium Carbonate (GCC) NCSU

Because of the hardness of limestone, the grinding process is energy-intensive. Anionic dispersants, including phosphates and acrylates, are used as grinding aids and to make the resulting slurry more stable in a colloidal sense. Papermakers commonly use ground limestone products that are "fine-ground" or "ultrafine-ground" with equivalent

Lime Production from Limestone Current Technology

Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.
