  • Parametric Studies of Cement Production Processes

    The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40 to 60 of production cost. Additionally the cement industry contributes around 5 to 8 of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

    Smaller particles reacts faster in the kiln but it is not the same as cement grinding where a narrow range of P.S.D. is normally maintained to control distribution range between 5 to 50 µm. But the size distribution for raw meal is quite wide as upper limit of size fraction can be as high as 125 µm.

    Grinding raw material and clinker causes considerable wear to the grinding mill. Starting the mill direct-on-line stresses the mill and the gearbox increasing the risk of gearbox failure and shortens the lifetime of mechanical equipment. VSDs help optimize the mill speed to match the material flow thus minimizing the wear of the grinding mill.

    Use of ball mills to grind clinker and raw materials From the turn of the 20th century rotary cement kilns gradually replaced the original vertical shaft kilns used originally for making lime. Rotary kilns heat the clinker mainly by radiative heat transfer and this is more efficient at higher temperatures enabling higher burning temperatures
