    Mercury emissions are typically higher in kiln operations with the raw mill-off ("direct" operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging Mercury emissions are typically higher in kiln operations with the raw mill-off ("direct" operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions. Get Price

  • Cement clinkerWikipedia

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
