摘要： A fluidized-bed classifier has a vessel defining a space divided into an upper fluidized-bed chamber and a lower gas chamber by a perforated dispersion plate having the shape of a funnel. Rising currents of a gas, such as air, are blown through the dispersion plate into the upper fluidized-bed chamber to produce a fluidized bed of a particulate material over the dispersion plate. The lower gas chamber is divided into a first gas chamber and a second gas chamber by a partition plate. The gas is supplied into the first air chamber so that rising gas currents of a velocity necessary for fluidizing coarse particles contained in the particulate material fed into the vessel are blown from the first air chamber through the dispersion plate into the fluidized-bed chamber. The gas is supplied into the second air chamber so that rising gas currents of a velocity lower than the velocity of the rising gas currents blown from the first air chamber into the fluidized-bed chamber are blown into the fluidized-bed chamber so that coarse particles contained in the particulate material are not fluidized and does not flow together with fine particles into a fine particle discharge chute.

摘要： The grinding efficiency can be improved by use of a vertical roller mill, while reducing the energy consumption and improving the product quality. The disclosed cement clinker grinding apparatus comprises a closed circuit for conveying the ground material from the vertical roller mill (21) to the external separator (28) by the bucket elevator (29), for classifying the conveyed material into coarse powder and fine powder, and further for returning the classified coarse powder into the vertical roller mill (21). That is, a part of the ground material conveyed by the bucket elevator (29) is divided by the distributing damper (32) and then directly returned to the vertical roller mill (21). Since the ground material are not conveyed by air flow conveyance (i.e., air sweep), it is possible to prevent an increase of power consumption of the suction fan (31). Further, since a part of the ground material is distributed by the distributing damper and then further ground again by the vertical roller mill, it is possible to obtain an optimum particle size distribution of the cement products, so that the cement quality can be improved.
摘要翻译：通过使用立式辊磨机可以提高磨削效率，同时降低能耗并提高产品质量。所公开的水泥熟料研磨装置包括用于通过斗式提升器（29）将立式辊磨机（21）输送到外部分离器（28）的接地材料的闭合回路，用于将输送的材料分类为粗粉末和细粉末，并进一步将分级粗粉返回立式辊磨机（21）。也就是说，由斗式提升器（29）输送的一部分地面材料被分配阻尼器（32）分开，然后直接返回到立式辊磨机（21）。由于未通过气流输送（即空气扫描）输送研磨材料，因此能够防止吸风机31的功率消耗的增加。此外，由于一部分研磨材料通过分配阻尼器分配，然后通过立式辊磨机再次进一步研磨，可以获得水泥制品的最佳粒度分布，从而可以提高水泥质量。

摘要： A method of grinding cement clinkers and a cement clinker grinding apparatus having a vertical roller mill are provided. In the method, feed material is ground by a table and rollers. Next, substantially all the resultant ground material is taken out from an underside of the table and then converted to a separator for classifying the ground material by a bucket elevator. The resultant coarse powder provided by the separator is returned to a center of the table. In grinding, an pressing force of each of the rollers onto the table is selected so that a roller pressure per full sectional area of the roller ranges from 10 to 15 kg/cm2. Further, a circulation quantity of the coarse powder to be returned to the vertical roller mill is selected from 100 to 300% of the feed material charged into the center of the table. And the liquid of 0.5 to 3% of the feed material to be ground such as water alone or a mixture of water and diethylene glycol is sprayed on the only frictional grinding zone which is positioned outside a position where a relative speed between said table and each of said rollers is equal to zero, in the radial direction of said table. By spraying the liquid on the only frictional grinding zone, the materials are involved firmly between the table and the roller to form the layer of the ground materials, so that the vibration of the roller and table are restrained

摘要： A grinding apparatus includes a roller mill in which material particles are pre-ground, a tube mill connected to the roller mill through a fluidized-bed-type classifying device in which the material particles are classified by size and a circulation line is connected between the classifying device and the roller mill, wherein a fluidized portion of the pre-ground particles, which consists of a fine material component is fed into a tube mill, a remaining portion of the pre-ground particles, which consists of course material and some amount of fine material not fed into the tube mill is returned to the roller mill through the circulation line where the remaining portion of the pre-ground particles is again crushed together with newly fed material particles in the roller mill. The fluidized-bed-type classifying device is provided with a first chute through which the fine material component flows out to the tube mill and a second chute connected to the circulation line through which the remaining portion is returned to the roller mill. The inner hollow space of the fluidized-bed-type classifying device is divided into an air introduction section and a fluidized bed section by a porous partition plate arranged horizontally with inclination toward the second chute. The fluidized bed section communicates with both the tube mill and the roller mill and the air introduction section communicates with the material fluidizing air which has a controllable flow rate.

摘要： A clinker cooler (3) comprises a plurality of grates (5) arranged in adjacent and overlapping relation to each other for conveying hot cement clinker (11) supplied from a kiln (1). The grate (5) is formed with an air hole (20) through which air from a fan (8) is jetted toward the cement clinker via a compartment (16) to cool the cement clinker. A distribution chamber (13) is equipped to a part of the grate corresponding to a part of cement clinker which is not cooled sufficiently, and the air from the fan (14) is jetted to such part of cement clinker which is not cooled sufficiently. The quantity of air jetted from the distribution chamber is adjusted by varying a degree of opening of a damper (15).

摘要： A probe having a double-tubed structure is provided to communicate with a kiln exhaust gas flowing path. A part of kiln exhaust gas is extracted through an inner tube of the probe, while cooling gas is supplied to a fluid flowing path formed between the inner tube and an outer tube of the probe. The cooling gas is guided to flow into an inner area of a front end portion of the inner tube so as to form a mixing and quick cooling area at a front end portion of the probe, thereby rapidly cooling the extracted gas.
