Clinker is ultimately ground to a fine powder in a cement mill and mixed with gypsum and other additives to obtain cement. The entire cement production cycle is hard to decarbonize, as only 40% of CO 2 emissions are associated with fossil fuel combustion while the major part is due to raw materials calcination in the cement kiln ( De Lena et al ...
Manufacturing 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. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
