The calcination process of kaolin rotary kiln

Kaolin calcining is the process of endothermic, decarbonization, dehydration, heat, phase transformation.Internal heating type rotary kiln of calcining , is essentially that when the calcining kaolin reached a temperature of exothermic peak, in a very narrow temperature range to control its temperature, to make it fully dewatering decarbonization, and does not cause the phase change, to maintain a desired physical properties.Internal heating type rotary kiln temperature calcines kaolin are following the intermediate routes as below: Feeding -- Heating (also quoted the wind) -- dehydration,decarburization-- heat releasing after heat,wind supply-- products quenching.

The features of kaolin rotary kiln

High white content, soft texture, easy to disperse and suspend in the water, fine plasticity, high cohesive property, good electric insulation property; Excellent anti-acid solubility, lower base exchange capacity, and pretty good refractory nature and such physicochemical property.

So kaolin has become an essential ore raw material in paper-making industry, ceramic industry, rubber industry, chemical engineering industry, paint industry, medical industry, defense industry and so on
