    专利说明:

    [001] The present invention relates to a two-cylinder crusher rotatably mounted in a crusher housing, the cylinders are driven synchronously in opposite directions by a motor, whose central axes are aligned parallel to each other, on which on the cylinder liners are provided with crushing teeth that protrude over the surfaces of the liners.
    [002] Two-cylinder crushers are, in particular, known and usual for the area of crushing technique in the mining industry. In usual two-cylinder crushers, large rocks or the like are crushed with the help of motor-driven cylinders. Normally, the cylinders are horizontally aligned, in which their central axes are aligned parallel to each other. The direction of rotation of the two cylinders is synchronously opposite and in such a way that normally the crushing material introduced by the upper part in the cylinder slot is captured by the rotation of the cylinders to be crushed by the crushing teeth of the cylinders. Then the material is discharged at the bottom from the cylinder slot. It is usual that crushing teeth are arranged on the cylinder liner by means of which the material is crushed. The grinding teeth are provided in a differentiated arrangement from each other on the cylinder liners. Preferably, they are respectively arranged so that, during rotation, the grinding teeth of one cylinder do not collide with the grinding teeth of the other cylinder.
    [003] A synchronization of the cylinders by means of a gear is also known.
    [004] In the classic two-cylinder crushers, an imaginary angular angle between the cylinder liners causes the feed material to stick to it and be crushed between the cylinder liners. A toothless cylinder liner captures the material due to this interlock. With this, seen in relation to the diameter of the cylinder, only a small stone can be inserted. In this case, the operating tangential opening angle is very small. The use of grinding teeth can significantly improve the pickup procedure depending on the geometry. The grinding teeth can have different contours, as, for example, they can be pointed teeth or they can be grinding teeth by chisel or hammer tip, which are fixed in a support on the cylinder liner, preferably, which can be exchanged, in the which such grinding teeth, for example, may have hardened tips and, preferably, project approximately tangentially to the shirt thereof. In the usual two-cylinder crushers, the grain size that is achieved by crushing the material fed through the two-cylinder crusher is determined by the crack in the cylinders. The gap in the cylinders, in turn, depends on the size of the tooth. A large gap with corresponding large teeth in the cylinder liner makes the final grain size relatively large. This means that, in practice, for pre-crushing, two-cylinder crushers with relatively large teeth are used. However, next, a second two-roller crusher is required for further crushing that has smaller teeth, whereby the gap in the cylinders is smaller.
    [005] Therefore, from this level of technique, the invention aims to create a two-cylinder crusher that allows a considerably greater crushing ratio between the material introduced and the material supplied which is extremely economical and to reach the final grain size no second configuration of another two-cylinder crusher is required.
    [006] For the solution of this objective the invention proposes that each crushing tooth of a cylinder of the pair of cylinders be designated a pocket on the surface of the sleeve of the other cylinder, so that in the rotation of the cylinders the crushing tooth is inserted in the pocket.
    [007] By means of the formation according to the invention it is possible to equip two-cylinder crushers with relatively large crushing teeth, while, however, the cylinder gap between the cylinders of the two-cylinder crusher can be adjusted very small. Due to the fact that each grinding tooth in a cylinder of one pair of cylinders is designated a pocket in the cylinder liner of the other pair of cylinders, in which the respective grinding tooth of the other cylinder can be inserted, on the one hand, allows the grinding teeth can have a large configuration so that they can also grind and press material into large fragments in the cylinder gap. On the other hand, this configuration creates the possibility of adjusting the relatively narrow cylinder gap between the cylinders. This also contributes so that large blocks of material to be crushed can be introduced and crushed, in which the final grain size of the material to be crushed is reached in just one passage through the two-cylinder crusher.
    [008] In this case, preferably, it is provided that the pocket size and the depth of the shape and size are adapted to the appropriate grinding tooth.
    [009] In addition, preferably, it is envisaged that the bag has a dimension that, in the rotation of the cylinders, on insertion, the grinding tooth does not come into contact with the bottom of the bag.
    [0010] In particular, preferably, it is provided that the bags and the grinding teeth are adapted to each other so that in the rotation of the cylinders there is a gap between the cylinder liners that is less than the height of the teeth of the cylinders. crushing.
    [0011] By means of the configuration according to the invention it is possible to achieve that the grinding teeth in their geometric extension do not collide with the cylinder liner of the respective other cylinder, however, however, there is still a proximity of the crack's reach formed between the two cylinders to make grinding possible. So that no collision occurs, the cylinder located, respectively, in opposition presents for each grinding tooth a cavity in which the tooth can be inserted without coming into contact with the cylinder liner. The geometry of the corresponding pocket or cavity results from the movement curve of the grinding tooth in relation to the cylinder body. The two-cylinder crusher according to the invention synchronizes the actuation of the cylinder, for example, by means of a branching gear. The configuration according to the invention achieves a very high crushing ratio of, for example, up to 1:20. Here, in relation to the conventional configuration, the use of a second two-roller crusher to reach the final grain size is also avoided. Thus, the efficiency is clearly increased. In addition, the space required for installation and use of the corresponding machine is reduced, so the two-roller crusher is improved. Regardless of the position of the grinding teeth, the principle according to the invention can occur in all possible directions of grinding teeth teeth in the cylinder liner. For example, there are known axially aligned arrangements on the cylinder liner, spiral displaced arrangements, positive or negative symmetrical V-shaped arrangements in relation to the center of the cylinder, irregular peripheral arrangements, chaotic arrangements on the cylinder liner. cylinder.
    [0012] In certain circumstances it can be advantageous when additional projections are provided on the cylinder liner, whose height is less than or equal to the gap between the cylinders.
    [0013] In this configuration, it is provided that additional crushing projections are provided on the cylinder liner, preferably on the liner of both cylinders. These crushing projections are arranged displaced in relation to each other on the cylinder liners, so that when rotating the cylinders they do not collide with each other. This type of crushing projection has only a relatively small height compared to the crushing teeth, however, it has the purpose of still crushing the grain that may have lodged in the crack. This subsequent grinding by the small teeth occurs without cavities for these teeth. The distance between the cylinders is only slightly increased by the small teeth. In any case, a slit of cylinders is necessary for the passage of the crushed material. This distance can be taken advantage of through the provision of additional crushing projections.
    [0014] In this provision, it can additionally still be provided that the crushing teeth and, as the case may be, the crushing projections are also arranged, respectively, on a peripheral liner line and each cylinder forms several peripheral liner lines parallel to each other and spaced apart from each other occupied with crushing teeth and, as the case may be, crushing projections.
    [0015] In this case, it can also be foreseen that the peripheral lines are formed by ring-shaped elevations in the cylinder liner that incorporate the crushing teeth and, as the case may be, the crushing projections.
    [0016] Furthermore, it is foreseen that the crushing teeth and, as the case may be, the crushing projections of one of the cylinders are axially displaced on its sleeve and, as the case may be, crushing projections formed on the shirt of the other cylinder.
    [0017] Examples of configuration of the invention are shown in the drawing and are described in more detail below.
    [0018] The figures show:
    [0019] figure 1: a view of the essential components of a two-cylinder shredder.
    [0020] Figure 2: they are partially fragmented.
    [0021] Figure 3: the same ones presented in a top view.

    [0025] Figure 8: the variant seen in section.
    [0026] The drawing shows the elements of a two-cylinder crusher 1 according to the invention. This type of two-cylinder crusher 2, 3 features two cylinders driven by the motor synchronously in opposite directions. In the configuration example, cylinders 2, 3 have shaft ends on their front sides that are installed in a corresponding crusher housing and are driven synchronously and in opposite directions by means of appropriate motor drive according to the movement of the arrows 4, 5. The central axes of the two cylinders 2, 3 are aligned parallel to each other. In normal case, this type of two-cylinder crushers is equipped with cylinders 2, 3, of horizontal alignment, in which, from the top of the cylinder gap between the cylinders 2, 3, the material to be crushed is introduced and captured while the crushed material is discharged from the bottom.
    [0027] On the cylinder liner 2, 3, crushing teeth 6, 7 are arranged in a multiplicity of individual elements that project, radially, through the surfaces of the cylinder liners 2, 3. According to the invention, in cylinders 2, 3 there are pockets (cavities) 8, 9, in a corresponding multiplicity and arrangement, by means of which, in the rotation of the cylinders 2, 3, the crushing teeth 6 or 7 can be inserted, respectively, in the pockets 8 , 9 from the other cylinder. The size of the cavities in the pockets 8, 9 and their depth are adapted to the shape and size of the corresponding crushing teeth 6 or 7, in particular, so that the crushing teeth 6, 7, in the rotation of the cylinders 2, 3, do not they come into contact, respectively, with the other cylinder, but if they insert themselves, almost without contact in the respective bag 8 or 9, they pass through it and can again leave the bag.
    [0028] As, for example, can be seen in figures 4 to 6, the bags 8 or 9 and the crushing teeth 6 or 7 are adapted to each other by the size and arrangement so that in the rotation of the cylinders 2, 3, it is a gap between the cylinder liners is kept which is less than the height of the crushing teeth 6, 7.
    [0029] In addition, on the cylinder liner 2, 3 additional crushing projections 10, 11 are formed, whose height is clearly less than the height of the crushing teeth 6, 7 and to which no corresponding cavities are assigned. The height of these additional crushing projections 10, 11 is adapted to the cylinder gap between the cylinders 2, 3, so that, in the operation of the two-cylinder crusher, they can pass the cylinder gap without coming into contact with the other one cylinder. These additional crushing projections are very useful for additional crushing of the crushed material by the crushing teeth 6, 7 and the cylinders 2, 3, so that the final result of a crushing can occur at a final grain size.
    [0030] As can be seen from the drawing figures, the crushing teeth 6, 7 and also the crushing projections 10, 11 are respectively arranged on a peripheral circular liner line, in which each cylinder has peripheral circular lines of shirts filled with several crushing teeth 6, 7 or crushing projections 10, 11 parallel to each other and spaced apart from each other. This type of circular lines is formed in the form of configuration according to figures 7 and 8 by elevations in the shape of a ring 12, 13 on the cylinder liner of cylinders 2, 3, in which these elevations 12, 13 in the shape of a ring incorporate the crushing teeth 6, 7 and the crushing projections 10, 11. Among these elevations in the shape of a ring 12, 13, the cylinder liner is formed smooth without elevations, in which, in this area, the configuration of the bags 8, 9.
    [0031] As it is possible to see from the configuration examples, the grinding teeth 10, 11 of a cylinder are formed, respectively, on his shirt, displaced axially in relation to the grinding teeth and grinding projections on the other's shirt cylinder.
    [0032] The invention is not limited to examples of configuration, but in the context of publication, in many cases, it is variable. All combined or individual characteristics published in the description and / or drawing are considered essential to the invention.
