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.
The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw.
