Calcined kaoline
We have calcined kaolin :calcination of crushed raw kaolin is done in a modern rotary kilnwith high efficiency . The fired kaoline grains have high density and volume stability .The chemical constitution and properities of the calcined kaolin grains are illustrated in the following table.
