    • The invention relates to a cement clinker manufacturing method implemented in a continuous production facility (1) having at least one area (2, 2') for fuel combustion for firing an inorganic raw material. In said method, the raw material is converted into clinker by firing, thus obtaining hot clinker (3), then the hot clinker (3) is cooled in two consecutive steps: a first cooling step, implemented in a first cooler (4); and a second cooling step, implemented in a second cooler (5). According to the invention, the first cooling step is continually carried out by blowing an oxygen gas (6) on the hot clinker to obtain partially cooled clinker, and all the heated oxygen gas (7), created by the first cooler (4), is sent to said at least one combustion area (2, 2') of said facility to be used as a combustion gas by adjusting the amount of oxygen gas, blown in the first cooler, such as to cover the combustion gas needs of said facility without any excess; and the partially cooled clinker (31) is stored in a storage chamber of the second cooler (5) or even a storage chamber associated with said second cooler, and the second cooling step is intermittently carried out on the partially cooled clinker.
    • 一种在连续生产设备中实施的水泥熟料制造方法,具有至少一个用于将无机原料焙烧成热熟料的燃料燃烧区域,然后将热熟料冷却为:第一冷却器中的第一冷却步骤; 以及在第二冷却器中的第二连续冷却步骤。 第一个冷却步骤通过在热熟料上吹氧来连续进行,以获得部分冷却的熟料,并且由第一冷却器产生的所有加热的氧气被送到燃烧区域以用作燃烧气体,通过调节 在第一冷却器中吹入的氧气量,以覆盖设施的燃烧气体需求而不会过量; 并将部分冷却的熟料储存在储存室中,并且第二冷却步骤在部分冷却的熟料上间歇地进行。

    • The invention relates to a device for the selective granulometric separation of solid powdery materials using centrifugal action, capable of separating materials into two fractions, i.e. a fine material fraction and a coarse material fraction, including: a housing (6), a cylindrical rotor (2) which is rotatable, relative to said housing, about a vertical axis inside said housing and provided with blades (3) evenly distributed on the periphery of an upper outlet opening though which a stream of gas, laden with particles having a size lower than a predetermined particle size, is drawn, a set of vertical adjustable vanes evenly distributed about the rotor along the generatrices of a virtual cylinder and directing the gas stream towards the rotor, means for feeding the particles between the vanes and the rotor, collecting means lower than the rotor for collecting the unfed particles having fallen and having a size larger than the predetermined particle size. According to the invention, said collecting means includes a peripheral system with a fluidised bed, wherein the bed extends about the rotor axis, at least underneath said vanes and the gap between the vanes (7) and the rotor (2), the speed of the fluidisation gas in a horizontal section of the fluidised bed being lower than 1 m/s so as to induce another separation of the fine materials and of the coarse materials in which said fine materials are fed back into the gap between said areas and said rotor.
