Burning in a kiln – formation of cement clinker
Cement kiln dust. As the hot kiln gas moves through the kiln, it carries with it the smallest particles of the raw mix as well as volatilized inorganic substances such as alkalis (sodium and potassium) and chlorides. As the gas cools, the volatiles condense back round the small particles, and the resulting powder is called cement kiln dust (CKD).
