Sep 08, 2015· Calcination is one of the most common processes used in the ceramics industry among many others. The most common application for Calcining is the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement. The product of calcination is usually referred to as "calcine," regardless of the actual minerals undergoing thermal treatment.

Jul 05, 2016· Calciner performs indirect high temperature processing (550-1150 °C) within a controlled atmosphere. Calcination is derived from a Latin word called calcinare which means "to burn lime". Calcination is most commonly applied in decomposition of calcium carbonate (lime stone) to calcium dioxide (lime) and carbon dioxide in order to make cement.
