Calcined Kaolin is produced by calcining (firing, sintering) kaolin clay or kaolinite rock (flint clay). Calcination is mainly carried out in rotary kilns, but also in shaft kilns, ring kilns and tunnel kilns. There are chamottes with different alumina contents and correspondingly different refractoriness. Depending on the chemical composition, different levels of corrosion and acid resistance are achieved. Fireclay can be supplied as a raw material in a fineness of 0 to 25 mm or 0 to 50 mm, but also in finished refractory grain sizes and finenesses.
