Definitions

  • the invention relates generally to the field of crushers, and more specifically relates to the field of cone or gyratory crushers.
  • Cone or gyratory crushers utilize a gyrating conical crusher head or cone head, which has secured to it an outer conical crushing surface or mantle typically made of manganese and which is a replaceable wear part.
  • the material is crushed between the stationary inner conical surface of a bowl liner and the gyrating outer surface of the crusher head mantle. Since the mantle must be periodically replaced it is typically attached to the crusher head by a head bolt. Due to the high forces involved it is often difficult to remove the head bolt, or it may become loosened prematurely.
  • a more effective crusher head design which comprises a novel compression bolt arrangement for replacing the head liner.
  • the compression bolt incorporates an array of tightening bolts which are aligned in a direction parallel to the outer surface of the head.
  • a compression washer is used between such bolts and the mantle whereby a surface of the compression washer bears against the upper surface of the head liner. The force of the bolts is thereby directed parallel to the surface of the head to most efficiently tighten the head liner against the head.
  • Figure 1 is a vertical cross-section of a cone crusher according to the invention.
  • Figure 2 is a vertical cross-section of the head assembly of the cone crusher shown in Fig. 1;
  • Figure 3 is a perspective view of the vertical cross-section of the head assembly of a cone crusher shown in Fig. 2;

  • Figure 13 is a perspective view of a second embodiment of the invention in which the compression bolt is structured as a nut rather than as a bolt;
  • Figure 14 is a perspective view of the compression bolt using an impact- wrench adapted attachment bolt. Description
  • cone crusher 10 has a stationary bowl liner 12, mounted in bowl 14 which has a central vertical axis 16 and feed opening 18.
  • Bowl liner 12 has a generally conical interior surface 20.
  • the crusher head assembly 22 extends upwardly into space 24 formed by bowl liner 12.
  • crusher head assembly 22 gyrates about the central axis 16 on head ball 26.
  • the crusher head assembly 22 is secured to head ball 26 by a nut 23 and socket washer 25. Head assembly 22 is thereby provided gyratory movement through head ball 26 which rests freely on socket liner 27 of socket 15 and main shaft 29.
  • a film of oil permits head ball 26 to move freely on socket liner 27.
  • Eccentric 17 is motor driven to provide an eccentric rotational motion which provides the head assembly with gyratory movement by contact of its outer surface on the inner surface of the head assembly 22.
  • the crushing surface of crusher head assembly 22 is formed by the head liner 28, which is typically formed of manganese, and requires periodic replacement.
  • Head liner 28 is fixed to the frusto-conical surface of head 30 by compression bolt 32.
  • Crusher head assembly 22 is shown in greater detail in Fig. 2 and 3.
  • Head 30 (Fig. 4, 5) has a frusto-conical surface 34 and an axially extending threaded aperture 36 with threads 38 which engage threads 40 on cylindrical bolt extension 42 of compression bolt 32 (Fig. 6, 7).
  • Compression bolt 32 has an upper flanged head 44 having an upwardly opening central hollow recess 46, and flange 48 having upper outer frusto-conical surface 50, lower outer frusto-conical surface 52 and inner frusto- conical surface 54.
  • An array of threaded passages 56 extend from surface 54 to surface 52. Threaded passages 56 receive threaded flanged bolts 58 (see Fig. 2 and 3) having complementary threaded surfaces.
  • a central threaded aperture 60 in compression bolt 32 receives a threaded bolt 62 which secures a cap 64 over the compression bolt 32.
  • Head liner 28 as shown in Fig. 8 and 9 has a generally frusto-conical inner surface 66, and outer surface 68 has multiple angled contiguous frusto-conical surfaces 70, 72 and 74. Three radially extending protrusions 76 serve to permit lifting of the head liner 28. The different lengths and angles of surfaces 70, 72 and 74 are selected to permit adjustment for the size of the material to be crushed and the size of crushed material. Inner surface 66 is preferably smooth but to avoid locking on the surface of head 30 may be provided with concentric grooves 67 to facilitate removal.
  • a compression washer 78 shown in Fig. 3, 10 and 11, transfers force along a vector tangential to the surface 34 of head 30, from flanged bolts 58 to surface 88 of compression washer 78.
  • Surface 86 of compression washer 78 bears against surface 80 of head liner 28.
  • the force of bolts 58 is thereby directed parallel to the surface 34 of head 30 to most efficiently tighten the head liner 28 against head 30.
  • Optional O- ring 90 (Fig. 3) may be provided to seal between cap 64 and compression washer 78.
  • head liner 28 is placed on head 30.
  • Compression washer 78 is placed against surface 80 as shown in Fig. 3.
  • Compression bolt 32 is threaded by hand into the head 30 to provide hand tightness of surface 52 against surface 88.
  • Bolts 58 are then tightened to tighten the head liner in place against the head 30.
  • Bolt 62 is then threaded into cap 64 and threaded into compression bolt 32 to secure cap 64.
  • bolt 62 is unthreaded to remove cap 64.
  • FIG. 13 illustrates a second embodiment in which the compression bolt instead is configured as a nut.
  • the configuration is the same as compression bolt 32 but in this embodiment the head 30 is provided with threaded bolt 84.
  • Compression nut 82 has a central threaded aperture 186 which engages the threads of bolt 84. Hand tightening of compression nut 82 on bolt 84 causes a surface of the compression nut to bear against surface 80 of the compression washer as in the previous embodiment.

Abstract

L'invention concerne une conception de tête de broyeur destinée à des broyeurs à cônes ou giratoires, laquelle comprend un nouvel agencement de vis de compression pour remplacer le manteau. La vis de compression incorpore un ensemble de boulons de serrage qui sont alignés dans une direction parallèle à la surface externe de la tête. Une rondelle de compression est utilisée entre ces boulons et le manteau, ce par quoi une surface de la rondelle de compression repose contre la surface supérieure du manteau. La force des boulons est ainsi dirigée parallèlement à la surface de la tête pour serrer plus efficacement le manteau contre la tête.
