Calcination process of bauxite

Bauxite Calcination Plant by Rotary Kiln with Fine Grinding Ball Mill. Refractory Grade Calcined Bauxite. 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 phase’s corundum and mullite are
