Description
Calcined bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures. This process of calcining (heating) bauxite in kilns removes moisture and gives calcined bauxite its high alumina content and refractoriness, low iron oxide, and grain hardness and toughness.
Its thermal stability, high mechanical strength and resistance to molten slags make Calcined Bauxite an ideal raw material in the production of many refractory, abrasive and specialty product applications.
