    摘要： The present invention relates to processes for disintegrating brittle materials using mechanical devices. The present invention can be used in all fields of industry where it is necessary to produce powders having a particle size ranging from several millimeters to nano-sizes. FIG. 1 illustrates the essence of the proposed grinding method. Grinding bodies (1) are situated in a single layer between two support surfaces (2). The gap between the grinding bodies (1) and the support surfaces is established and regulated to be less than 0.86 of the diameter of the grinding body (1), thus automatically maintaining the grinding bodies (1) in a single layer. Particles of starting material (3) are fed onto one of the support surfaces (2) which is displaced relative to the grinding body (1) and to which rotational motion is imparted by means of friction with said support surface (2). The particles of the starting material (3), because their size is 15-20 times smaller than the diameter of the grinding body, (the capture angle of the particles of starting material (3) by the grinding body (1) is smaller than the angle of friction of the material of the particles of starting material (3) against the material of the grinding bodies (1)), are pulled under the the grinding body (1) and, because the vertical displacement of the grinding body (1) is limited by the second support surface (2), the particles of starting material (3) are thus crushed by the grinding bodies (1).

    摘要： A multi-sectional roller mill comprises at least two mill sections (2, 2′) each including a plurality of ‘rollers (20, 20′), wherein each mill section includes a-drive shaft (16, 16′) and male and female parts of a coupling element (15) attached to respective ends of said drive shaft for rotation therewith, and wherein the said coupling element provides for rotation between said male and female parts of drive shafts of adjacent mill sections.

    摘要： A grinding mill requiring one or more new grinding balls is adapted so that they can be passed into the mill through spider-guide apertures. The spider-guide apertures provide anchors for spider-guide mountings, by means of which a spider used to grip an upper ring is restrained against rotation. There may be provided two mounting frames between the spider-guide mounting, and the mill. Frame is secured to the mill and has a large opening, able to pass a grinding ball. Frame is secured to frame and has a smaller opening, and provides a mounting location for the spider-guide mounting. The arrangement means that mill disassembly and lifting then lowering grinding balls is no longer needed.

    摘要翻译： 需要一个或多个新的研磨球的研磨机被调整成使得它们可以通过蜘蛛引导孔进入研磨机。 蜘蛛引导孔提供用于蜘蛛引导安装件的锚固件，通过该锚固件可以限制用于夹紧上环的蜘蛛旋转。 在蜘蛛引导安装件和磨机之间可以设置两个安装框架。 框架固定在磨机上，并具有大的开口，能够通过磨球。 框架固定在框架上，并具有较小的开口，并为安装蜘蛛导板提供安装位置。 该装置意味着不再需要轧机拆卸和提升，然后降低磨球。
