A ROTARY KILN is a Direct Fired, Refractory Lined equipment for high temperature applications where it is necessary to change the 'state' of the material in a continuous process or in batch type process.
Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.
