The cement kiln is a typical example of a sintering furnace. Kilns are used in the cement industry for calcining lime and are made in various forms. Rotary cement kilns as used in the cement industry take the form of a long cylinder supported on rollers. They vary greatly in diameter and length, from 1.5 × 18 m to 4 × 140 m.
The cement kiln heats all the ingredients to about 2,700 degrees Fahrenheit in huge cylindrical steel rotary kilns lined with special firebrick. Kilns are frequently as much as 12 feet in diameter—large enough to accommodate an automobile and longer in many instances than the height of a 40-story building.
Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant the kiln, the cement mill etc..
