standard material selection for cement rotary kiln pdf

produced by introducing the raw material (highly siliceous clay, shale, or slate) into a rotary kiln, similar to the type used in the Portland cement industry. As it passes through the kiln, the material reaches temperatures greater than 1800 F and begins to turn plastic. Internal gases cause

The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water
