Definitions

  • My invention relates to an improvement in wearing parts for gyratory crushers and has for one purpose the provision of an improved mantle for such a crusher which shall be quick and easy to apply and remove and which shall be selftightening in use.
  • Another purpose is the provision of improved means for securing such a mantle in position.
  • Another purpose is the provision of an improved mantle in which part of the locking means are formed integrally with the mantle.
  • Another purpose is the provision of a mantle of manganese steel or the like in which the locking means include a portion of the mantle adapted to yield or compensate for peening or stretching of the body of the mantle during use.
  • Another purpose is the provision of an improved mantle adapted to prevent relative movement of the mantle and of the soft metal packing or backing which is employed with it.
  • Fig. 1 is a vertical section illustrating one of the improved mantles in position
  • Fig. 2 is a section on the line 2-2 of Fig. 1;
  • Fig. 3 is a plan view of one of the mantles
  • Fig. 4 is a section on the line 44 of Fig. 3;
  • Fig. 5 is a partial plan view illustrating a variant form of the mantle
  • Fig. 6 is a vertical axial section through a variant locking means
  • Fig. 7 is a section on the line 1--'
  • My mantle is illustrated in connection with a so-called gyratory cone crusher.
  • the crusher itself does not form part of the present invention and is not indicated in complete detail.
  • I illustrate, however, a cone or head I, which is mounted upon an upright portion 2, fixed on any suitable crusher base not herein shown.
  • the portion 2 is in the form of a cylindrical member fixed on the crusher frame. Rotatable thereabout is an eccentric sleeve 3, which may be rotated by any suitable means not herein shown.
  • I may employ suitable bearing liners or sleeves 3a and 3b.
  • the inner wall of the eccentric aperture of the sleeve 3 is in bearing relationship with the cylindrical exterior surface of the member 2.
  • outer surface of the eccentric sleeve 3 which is also cylindrical but inclined to the inner surface, is in bearing relationship with a corresponding inner cylindrical surface of the head i.
  • the vertical center line of the crusher is ill-- dicated at X.
  • the head I is generally conic, but has a transversely extending top portion 4, which continues upwardly in a stem 5, herein shown as generally cylindrical.
  • ii is any suitable securing screw which prevents endwise movement of the key l0.
  • i2 is any suitable ieed distributing plate, which may be mounted on or form part of the above described structure.
  • l4 indicates any suitable packing or backing of soft metal, such as zinc, between the outer face of the wall I and the inner face of the mantle 6.
  • the mantle 6 is provided with a lower conic surface I5, which abuts against a corresponding surface at a lower portion of the head I.
  • the mantle 8 is outwardly recessed, as at It, and, if desired. the head may be inwardly recessed, as at ll.
  • a space is provided for the packing or backing ll of zinc or the like.
  • I may provide any suitable means to maintain an interpenetration of the two metals.
  • I illustrate, for example, a plurality of recesses l8.
  • other means such as a mere roughening of the inner wall of the mantle, may be employed. What is essential is that there shall be some gripping or interpenetration whereby, when the mantle moves in relation to the head, the packing or backing of zinc or the like moves with it.
  • the thread 1 extends about an arc of 360 degrees.
  • the thread is shown as extending about precisely 360 degrees of arc. It will be understood, however, that it may extend somewhat more or somewhat less than 360 degrees.
  • a variety of forms of thread may be employed. but I find it desirable to have the top or thrusthis face of the thread generally fiat and generally perpendicular to the axis of the nut or sleeve 9.
  • Fig. 5 I illustrate a thread la, which may be identical with the thread 1 of Fig. 4, but which is interrupted at a plurality of points, as at lb.
  • manganese steel a metal which is highly resistant to wear and which can stand up under the crushing impacts of a gyratory crusher.
  • One characteristic of this metal is that it peens or stretches under use. This peening or stretching or distortion of the mantle tends to throw a heavy stress on whatever locking means are employed. I find it desirable, therefore, to provide locking means which may give or flex slightly, in order to compensate for this stretching action. I, therefore.
  • I illustrate the thread of the mantle as being a left-hand thread. While I illustrate a lefthand thread, this is not compulsory and I could employ a right-hand thread with equal effect.
  • the pitch of the thread is so related to the direction of movement of the head that whatever rotation is given to the head in the course of the crushing operation is effective to tighten the mantle.
  • 25 indicates a crushing bowl, which may form part of or be mounted on any suitable crushenframe, not herein shown. It includes a generally cylindrical outer wall 25, and an upwardly and inwardly inclined inner wall 2i, and a plurality of generally vertical ribs 28, which may terminate inwardly of a top supporting face 29 of the wall 21, the supporting face 29 being generally horizontal.
  • a rotatable locking nut having an inner locking thread 3
  • It is'shown as having an inner face 33a, which is generally conic and which, with the outer face of the mantle 3, defines a crushing cavity.
  • the lower portion of the face may be at a more obtuse angle, as at 35, and is shown as in parallelism with the opposed face of the mantle 6. That is to say, the opposed faces are generally parallel when the mantle 6 is at its closest or crushing approach to the bowl liner 33.
  • the liner 33 is provided with a lower conic outer face 35, which is adapted for a metal to metal contact with an opposed face 38 of the wall 21. Above such zone of contact the liner 33 is inwardly reduced, as at 31, to give room for a body of soft metal 38 of zinc or the like.
  • a thread 40 which preferably extends about the liner through an angle of arc It is shown as Precisely 360 degrees, but it will be understood that it may be made somewhat more or somewhat less than 360 degrees under some circumstances.
  • I illustrate a lower locking nut 50, having a thread 5
  • This nut fits around the lower part of the stem or extension 5 of the head and is held against rotation by any suitable means, such as the key 52.
  • the upper nut 53 is threaded to a, screw threaded upper portion 5a of the stem 5. This upper nut 53 bears against the top of the lower nut 50.
  • the upper nut 53 is secured against rotation by any suitable locking means.
  • .1 illustrate, for example, a locking member 54, which has a key projection 55 fitting in a slot 55 in the upper stem projection 5a.
  • the looking member 54 has a series of projections 51 on the outside which fit into cored recesses 58 in the upper nut 53, and a block of wood or equivalent material 59 may be inserted between the top of the member 54 and the feed plate 60.
  • the feed plate 66 is secured to the top of the upper nut 53 by the threaded bolt 6!.
  • Manganese steel for the wearing parts of gyratory crushers of the type herein shown.
  • Manganese steel possesses extreme toughness and wear-resisting characteristics. It has the peculiar characteristic of flowing or deforming under the pounding or impact normal to the crushing operation. It is, therefore, a difiicult problem to provide means for adequately holding the mantles in position and to provide for their ready removal for replacement.
  • this thrust transmitting means integral with or part of the mantle itself, which can be cast unitary with the mantle. This is a matter of convenience rather than necessity, and a takeup means of the type herein shown could be interposed between the top of the mantle and the locking nut or looking sleeve thereabove.
  • I employ a mantle body that is of manganese steel, which has adjacent its upper edge a single left-hand thread of about 360 degrees of arc. This is not a thread formed in the mantle so much as a thread which extends inwardly from the mantle. It will be. understood that the thread is not cut in the mantle, and the mantle is not weakened by the thread, the thread 1 extending laterally from the mantle itself, to a distance sufficient to provide the possibility of flexure of the thread to relieve an undesired upward thrust against the thread 8 of the locking nut or sleeve 9. It will be noted also that the outer edge of the thread 8 of the nut does not extend to the inner face of the mantle, but is spaced substantially inwardly therefrom.
