How Coal Works | Union of Concerned Scientists

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.


Coal Mill Function In Cement Plant Pdf

Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5 ~ 1.5, while that of raw coal is 1.5 ~ 4.0 . Therefore, the ball mill should have drying function besides grinding.
