The pellets are baked hard in a preheating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.
Typical process flow of a cement plant Raw material preparation Limestone is the predominant raw material. That''s why most plants are situated near a limestone quarry in order to minimize the transportation cost, since one third of the limestone is converted to CO 2 during the pyroprocessing and is subsequently lost.

vegetation. Through this process, habitats can be altered or destroyed. The quarrying sector''s primary impact on biodiversity is through the removal of surface features during the extraction of minerals (BBRC, 2012). One of the biggest negative impacts of quarrying on the environment is the damage to plant
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
