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

Dec 30, 2019 Most Portland cement plants are located very near limestone quarries, so their inbound supplies are usually limited to fuel (often coal), kaolin or bauxite, gypsum, and bags if the plant sells it that way. In the days before covered hoppers (late 1930s), most cement was shipped in barrels in boxcars so they would also get cooperage supplies
