Grinding: In the grinding process, the limestone is ground to a fine powder. Calcination: The limestone (CaCO 3) is heated in a rotary or shaft kiln where it breaks down into calcium oxide, i.e. quicklime (CaO), and carbon dioxide (CO 2). Crushing: The quicklime is reduced into different sizes. Grinding: The crushed quicklime is ground into a ...
