Definitions

  • My invention relates to an improvement in wearing parts for gyratory crushers and has for one purpose the provision of an improved bowl liner for such a crusher which shall be quick and easy to apply and remove and which shall be self-tightening in use.
  • Another purpose is the provision of improved means for securing such a bowl liner in position.
  • Another purpose is the provision of an improved bowl-liner in which part of the locking means are formed integrally with the bowl liner.
  • Another purpose is the provision of an improved bowl liner of manganese steel or the like in which the locking means include a portion of the bowl liner adapted to yield or compensate for peening or stretching of the body of the bowl liner during-use.
  • Another purpose is the provision of an improved bowl liner adapted to prevent relative movement of the bowl liner and of the soft metal packing or backing which is employed with it.
  • Fig. 1 is a vertical axial section illustrating one of the improved bowl liners in position
  • Fig. 2 is a section on a reduced scale taken on I v the line 2-2 of Fig. 1;
  • Fig. 3 is a side elevation of one of the bowl liners
  • Fig. 4 is a plan view of a variant form of my bowl liner.
  • Fig. 5 is a side elevation similar to Fig. 3 ofthe variant form of the bowl liner.
  • My liner is illustrated in connection with a socalled gyratory cone crusher.
  • the crusher itself does not form part of the present invention and is not indicated in complete detail. I illustrate,
  • 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.
  • the 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 indicated 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- 8 is any suitable removable mantle, the details of which do not form part of the present invention. .1 illustrate it,
  • any suitable feed distributing plate which may be mounted on or form part of. the above described structure.
  • Y indicates the center line or axis of the head.
  • i4 indicates any suitable packing or backing nate inwardly of a top supporting face l9 of the wall H, the supporting face I9 being generally horizontal.
  • a rotatable locking nut having an inner locking thread 21, and a plurality of upwardly extending lugs 22, whichv may be employed for rotating the locking nut 20 and for thereby tightening the below described bowl liner 23.
  • It is shown as having an inner face 23a, which is generally conic and which, with the outer face of the mantle 6, defines a crushing cavity.
  • the lower portion of the face may be at a more obtuse angle, as at 24, 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 23.
  • the liner 23 is provided with a lower conic outer face 25, which is adapted for a metal to metal contact with an opposed face 26 of the wall ll. Above such zone of contact the liner 23 is inwardly reduced, as at 21, to give room for a body of soft; metal 28 of zinc or the like. Relative rotation of the body of zinc and the liner 23 may be prevented by any suitable means.
  • I illustrate, for example, a plurality of further recesses or depressions 29, herein shown as four in number. It will be realized thattheir shape and number may be widely varied, and in fact, under some circumstances, a mere roughening of the rear face of the liner may be enough. What is important is that there shall be some interpenetration of the bowl liner and the zinc, whereby the body of zinc which backs the bowl liner and separates it from the opposed face of the wall I! shall be held against movement in relation to the bowl liner itself.
  • a thread 30 is preferably integral with the outer face of the bowl liner and herein shown as at the top of the bowl liner. It is shown as precisely 360degrees, but it will be understood that it may be somewhat more or somewhat less than 360 degrees under some circumstances.
  • the thread of the bowl liner is a left-hand thread. While I illustrate a left-hand thread, this is not compulsory and I could employ a right-hand thread with equal efiect.
  • 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 crushin operation is efiective to tighten the bowl liner.
  • the bowl liner In the application of the bowl liner it is moved upwardly into the position in which it is shown in Fig. 1, and any suitable means not herein shown may be employed for pouring the zinc backing 28.
  • the locking ring is tightened by sledging against the upwardly extending lugs 22 until the desired adjustment or tightening is obtained. Thereafter relative movement of the locking nut and the bowl vstructure is prevented by positionirg a locking ring III, which has a plurality of inward notches 4
  • the hopper or conic feed deflector 45 may be positioned as shown in Fig. 1, and the device is ready for use. It will be observed that the number of notches ll and 42 substantially exceed the number of lugs 22 and ribs l8, respectively, whereby a latitude of adjustment is permitted.
  • a discontinuous thread 30a which is provided with a plurality of notches 30b, which divide it into segments, which may flex independently in the course of compensation for the peening or stretching of the bowl liner.
  • thread I has shown the thread I as having a flat top, it will be understood that a wide variety of forms of thread may be employed, either standard or of specia1 design.
  • Manganese steel possesses extreme toughness and wear-resisting characteristics. It has the peculiar char acteristic of flowing or deforming under the pounding or impact normal to the crushing operation. It is, therefore, a difi'icult problem to provide means for adequately holding the. bowl liners in position and to provide for their ready removal for replacement.
  • I employ a liner body that is of manganese steel and has adjacent its upp r edge a single left-hand thread of about 360 degrees of arc. This is not a thread formed in the liner, so much as a thread which extends outwardly from the body of the liner. It will be understood that the thread is not cut in the liner and that the liner is not weakened by the thread.
  • the thread 30 extends laterally outwardly from the body of the liner itself to a distance sumcient to provide the possibility of flexure of the thread to relieve any undesired thrust against the thread 2
  • the thread therefore, not merely cooperates in holding the liner locked in position, but tends to serve as an automatic tightening takeup means during use, and also as a relieving means for compensating or relieving whatever undesired thrust is caused by the stretching or defamation of the liner resulting from the pounding it receives during the crushing operation.
  • the deformability of the thread 30 is highly important in connection with the automatic locking feature.
  • the bowl liner 23 is free to rotate within the bowl. The minute that the peening or stretching releases it in the bowl, it then rotates, and this rotation, due to the pitch of the thread, results in an upward thrust against the thread. If the liner were not free to rotate, this phenomenon would not occur, butin the crushing operation tremendous force is exerted on the bowl liner and mantle, tending to rotate these elements, and in the structure herein described and claimed I employ this force a'utomatlcalkv'to tighten the bowl liner and the mantle in place.
  • the deformability of the thread 39 of the liner or the thread i of the mantle prevents the exertion of any disadvantageous strain on the locking means employed.
  • a gyratory crusher having a bowl and a head, and means for gyrating the head, aliner for said bowl, including a generally conic body, and means for locking said liner in relation to said bowl, including an integrally formed thread outwardly extending from an upper portionof the liner, and a locking nut rotatably mounted on said bowland having a thread in mesh with the thread of said liner, means for rotating saidnut and for thereby exerting compression against the liner, including oneor more sledging lugs extending upwardly from said nut, and means for look- 'ing said nut against rotation in relation to said bowl, including a locking ring having apertures adapted to receive said sledging lug or lugs, and
