What Is Cement Rotary Kiln. Cement rotary kiln, also called cement kiln, is a pyroprocessing device used for calcining cement clinker in cement production lines.It is the main engine in the cement manufacturing process, commonly known as the “heart” of the cement plant.In the production process, an equipped kiln burner produces heat by
2022/6/2 Cement Kilns: Background. Cement kilns date back to the invention of Portland cement in 1824. It is named after Portland, England. In 1885, rotating horizontal kilns began to replace the original vertical, stationary kilns. Within five years, horizontal kilns dominated. In 1909, Thomas Edison received a patent for a long kiln almost
