are limestone, quicklime, and hydrated lime. Limestone is rock composed of at least 50% calcium carbonate and various impurities. A common im-purity is magnesium carbonate; when present in less than 5%, the limestone is referred to as high-calcium. A lime-stone containing 30-45% magnesium carbonate is classified as dolomitic stone.

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 ...
