making of portland cement rotary kiln method

The cement kiln

Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.

Rotary Kiln Cement Plant Cement Rotary Kiln AGICO

The rotary kiln cement plant can be divided into dry method cement plant and wet method cement plant. Their main difference lies in the cement rotary kiln. Raw meal calcined in the wet method kiln is a slurry containing 32% to 40% moisture, so the kiln body is longer and the clinker produced is of high quality with small dust pollution.
