Abstract: The present invention relates to an apparatus for manufacturing a cement clinker which comprises: a first mixing and melting region which mixes and melts sub-material flowed in from a first inlet and molten slag flowed in from a second inlet; a second mixing and melting region which mixes and melts products from the first mixing and melting region for the second time; a first clinkering region which selectively sorts unreacted sub-materials which passed the second mixing and melting region to discharge to the lower part and clinkers remnants from the sorting process; and a second clinkering region which clinkers products passed through the first clinkering region to discharge for cooling and pulverizing processes. According to the present invention, molten slag which is wasted as a byproduct in iron industry is recycled and is environment-friendly. In addition, using the heat of slag in molten condition at a high temperature enables energy sources for manufacturing a clinker to be reduced and reduces CO2 generation due to combustion of fuel. Furthermore, processes for manufacturing clinkers are continuously performed to improve productivity, thereby ensuring uniform physical properties and quality of products.

Abstract: Described is a method as well as a plant for preheating particulate or pulverulent material such as cement raw meal or similar material in a cyclone preheater (1), comprising at least two cyclone stages, each comprising a riser duct (2a, 2b, 2c, 2d) and a cyclone (1a, 1b, 1c, 1d). The method is peculiar in that a portion of the material which is fed to at least one cyclone stage is introduced to the first part of the riser duct, viewed in the direction of travel of the exhaust gases, and is heated from a temperature of maximum 450 °C to a temperature of at least 550 °C, and in that the remaining material which is fed to the same cyclone stage is introduced into the last part of the said riser duct. As a result, there will be a reduction in the amount of SO2 which is discharged from the cement plant preheater as emission, without a simultaneous increase in energy consumption.
