Rotary kiln bauxite powder 325mesh in refractory
Rotary Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 – 1800 degree Celsius. In this calcination process, the high refractory mineral phases corundum and mullite are formed. Refractory grade bauxite has high refractoriness, good mechanical strength, and moderate slag resistance. Therefore calcined bauxite is one
