    • A method of grinding cement clinkers and a cement clinker grinding apparatus having a vertical roller mill (11) are provided. In the method, feed material is ground by a table (13) and rollers (16). Next, substantially all the resultant ground material is taken out from an underside of the table and then conveyed to a separator (37) for classifying the ground material by a bucket elevator (38). The resultant coarse powder (46) 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/cm 2 . 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 (Z2) 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 (Z2), the materials are involved firmly between the table (13) and the roller (16) to form the layer of the ground materials, so that the vibration of the roller and table are restrained
    • 提供磨碎水泥熟料的方法和具有垂直滚磨机（11）水泥熟料研磨设备。 在该方法中，进料是由表（13）和辊子（16）接地。 接着，基本上所有所得地面材料的从在表中的下侧取出，然后输送到用于由斗式提升机（38）的地面材料进行分类的分离器（37）。 由分离器提供所得到的粗粉（46）返回到表中的一个中心。 在磨到走上被选择的表按压每个辊的力，从而确实从10至15千克/厘米<2>每辊范围的全截面面积的磨滚压力。 此外，粗粉末的循环量被返回到垂直滚磨机被从装入台的中心进料的100至300％选择。 和进料的0.5〜3％的液体被粉碎：例如单独的水或喷洒在其上的位置外侧的位置的唯一的磨擦碾磨区（Z2）的所有的水和二甘醇的混合物，其中所述之间的相对速度 表和每个所述滚轮是等于零，在所述表中的径向方向。 通过在仅磨擦碾磨区（Z2）喷射液体，所述材料涉及到的表（13）和所述辊（16），以形成研磨材料层之间牢固，所以没有辊与表的振动是 约束

    • A grinding apparatus includes a roller mill (10) in which material particles are pre-ground, a tube mill (40) connected to the roller mill (10) through a fluidized-bed-type classifying device (30) in which the material particles are classified in the sizes under control, and a circulation line (20) is connected between the classifying device (30) and the roller mill (10), wherein a fluidized portion of fine material component is fed into the tube mill (40), a remaining portion of not fed to the tube mill (40) is returned to the roller mill (10) through the circulation line (20) and the returned portion of the material component is again ground together with newly fed material particles in the roller mill (10). The fluidized-bed-type classifying device (30) is provided with a first chute (35) through which the fine material component is flowed out to the tube mill (40) and a second chute (36) connected to the circulation line through which the remaining material component is returned to the roller mill (10). The inner hollow space of the fluidized-bed-type classifying device is divided into an air introduction section (34) and a fluidized bed section (33) by a porous partition plate (32) arranged horizontally with inclination toward the second chute (36). The fluidized bed section (33) is communicated with both the tube mill (40) and the roller mill (10) and the air introduction section (34) is communicated with the material fluidizing fluid, such as air, of which a flow rate is controllable.
