Rotary kiln bauxite-Calcined bauxite, refractory grade …
Rotary kiln bauxite. As the name suggests, rotary kiln bauxite is the bauxite produced by rotary kiln. There are three kinds of kilns for bauxite production mainly, rotary kiln, shaft kiln and round kiln. Comparing with other two kinds, rotary kiln bauxite is caldined more evenly, benefits from the contnuous rotary movement of the kiln body.

Chamotte is a calcined clay. The calcination process takes place in a rotary kiln at high temperatures of 1400 - 1600ºC. Sanitaryware pieces are fired at lower temperatures of around 1200ºC, therefore the chamotte is inert at the firing stage and acts like a skeleton to produce ware with better proprieties.
