Abstract: Described is a method as well as a plant for manufacturing cement clinker, by which method cement raw materials are preheated in a preheater (1), calcined in suspension with hot gases in a calciner (2, 20), separated from the gases in a cyclone (2a), burned into cement clinker in a kiln (3) and subsequently cooled in a cooler (4) by which method a quantity of calcined raw material with a high content of CaO is extracted via a calcination stage (2, 20) by means of an additional separation cyclone (5a). The method and the plant are peculiar in that the gases which are diverted from the additional separation cyclone (5a) are cooled to a temperature of maximum 850 °C by means of cement raw materials which are introduced into the gas stream. It is hereby obtained that the quantity of material which is extracted by means of the additional cyclone can be adjusted by means of known means in a more reliable manner than has hitherto been possible, while also significantly reducing the risk of alkali-induced clogging. This is due to the fact that the lower temperature allows utilization of generally known control means and the fact that the alkali in the gases will condense and settle on particles in the gases at temperatures which are lower than 850 °C.

Abstract: Described is a method as well as a plant for drying and comminution of moist, mineral raw materials, such as chalk, marl and clay, by which method the raw materials are dried and comminuted subject to simultaneous supply of hot gases in a drier crusher (8) from which the material is subsequently directed in suspended form to a separator (11) in which it is separated into a coarse fraction which is returned to the drier crusher (8) for further drying and comminution and into a fine fraction which is directed to the next stage of the process and where any hard material components such as flint, sand and marble are subjected to grinding in a separate grinding unit (16). The method and plant is peculiar in that a part quantity of the coarse fraction from the separator (11) is proportionately fed to the separate grinding unit (16) for the grinding of hard material components. Hence, it will be possible to substantially reduce the specific energy consumption and the CO2 emission from the kiln system due to the elimination of need prior to drying and comminution in the drier crusher to suspend the raw materials in water which must subsequently be removed. This is ascribable to the fact that the hard material components by the method according to this invention will be drained away from the circuit between the drier crusher and the separator. A further advantage of the method according to this invention is the significant reduction achieved in the wear rate of the drier crusher and its energy consumption. Furthermore, it will be possible to produce a raw meal with excellent burning characteristics due to the reduction in the content of coarse silica particles in the raw meal, which in turn will reduce the NOx emission from the kiln.

Abstract: Described is a method as well as an apparatus for incineration of combustible waste during the manufacture of cement clinker by which method the waste is introduced via a waste inlet (11) and supported on a supporting surface (21) incorporated in a separate compartment (9), where the waste being actively transported, while simultaneously subjected to incineration, through the compartment to its outlet (23), where the hot exhaust gases produced in connection with the incineration of the waste being vented to the preheater system for heating the cement raw meal, and where the slag generated during the waste incineration process being extracted from the compartment (9). The method and the apparatus are peculiar in that exhaust gases containing NOx are introduced to the compartment (9).

Abstract: A conveyor for pulverized material comprises in combination a conduit, a screw rotatably mounted within the conduit having a material inlet end and material discharge end, means for rotating the screw, means for supplying material to the screw at the material inlet end, whereby the material will be compacted as it is advanced by the screw to the material discharge end, and means for admitting a gas under pressure to the compacted material at the material discharge end to render it fluent. In a portion of the screw a material seal is formed by the compacted material being advanced by the screw, wherein there are material pockets formed between adjacent screw flights, wherein the pocket size volume is at its maximum nearest the material inlet end and at its minimum nearest the material outlet end, with at least twice as many pockets of minimum size as of maximum size.
