Basic kiln hoods successful and innovative refractory

The kiln hood of a rotary kiln in a cement plant connects the hot area of the kiln with the clinker cooler and is therefore always exposed to high thermal and process-related stresses. In recent decades, these loads have steadily increased in consequence of the use of alternative fuels and thereby induced higher process temperatures.
