  • FIGURES 1 and 2 one embodiment of the liner structure of this invention has been shown at as comprising a truncated conical liner crushing member 12 and mounting means 13 for securing the crushing member 12 to a crusher bowl.
  • the liner crushing member 12 is formed with an inner conical crushing surface 16 and an outer conical backing or support surface 18.
  • the crushing member 12 of FIGURE 2 has been shown as having a particular cross section, it will be understood that the crushing member cross-sectional shape may be widely varied. For example, the angle of inclination of the surfaces 16 and 18 may be increased or decreased, etc.
  • the liner mounting means comprise a plurality of circumferentially spaced, radially extending mounting lugs or hooks 14 suitably secured or anchored to the liner crushing member 12 by a plurality of T-shaped feet 22 which are imbedded within the crushing member 12.
  • the T-shaped feet 22 extend from an elongated base portion 20 of the hook 14.
  • each liner mounting hook 14 has been shown as having three generally equally spaced feet, it should be understood that more or less than three feet may be used and that the spacing may vary. Further, it should be understood that the T-shaped feet may be eliminated.
  • the liner mounting hooks 14 may be interconnected by arcuately formed tiebars or rods 24 which are imbedded within the crushing member 12.
  • the tie-rods 24 have been shown welded or otherwise suitably secured at each end to the T-shaped feet of the mounting hooks 14.
  • each tie-rod 24 extends between any two successive liner mounting hooks 14; and as shown in FIGURES 1 and 2, each tie-rod is preferably staggered so that it is axially offset from the preceding and succeeding tie-rod, It should be understood, however, that successive hook 14 may be connected by more than one tie-rod 24 and that successive tie-rods 24 may be axially aligned, Further, it should be understood that the T-shaped feet may be eliminated and the tie-rods 24 may be secured to the base portion 20 of the hooks 14.
  • the liner crushing member 12 may have retaining rings 30 imbedded or in cavities therewithin which are spaced from each other and spaced relative to surface 18 by back spacers 32.
  • the liner mounting hooks 14 and tie-rods 24 are preferably made using a mild steel, but it will be understood that any tough, fracture-resistant metal may be used.
  • tie-rods 24 may be eliminated.
  • FIGURE 4 A further modification is shown in FIGURE 4 wherein the retaining rings 30 and back spacers 32 have been eliminated.
  • FIGURE 5 another embodiment of the liner structure of this invention has been shown at 34 as comprising an annular liner crushing member 36 and mounting means 38 for securing the crushing member 36 to a crusher bowl.
  • the crushing member 36 is formed with a cylindrical portion 40 and a conical portion 42 which forms a conical crushing surface 44.
  • the mounting means 38 may include an annular jacket 46 having a conical portion 48 and a cylindrical portion 50.
  • the cylindrical portion 50 is formed with a guide flange 52 and a suitable upper mounting flange 54.
  • the jacket 46 has been shown secured to the crushing member 32 by a plurality of T-shaped feet 56 extending from the jacket 46 and imbedded within the crushing member 36.
  • the T-shaped feet may be peripherally continuous or they may be interrupted.
  • the jacket 46 may be formed as one continuous annular piece or may be formed by a plurality of arcuate segments. Further, the jacket may be formed to back or cover the entire axial outer surface of the crushing member 36 as shown in FIGURE 5, or it may cover just a portion of such surface.
  • the jacket 46 is preferably made using a mild steel, but it will be understood that any tough, fracture-resistant metal may be used.
  • the crushing member 36 may have retaining rings 30 imbedded or in cavities therewithin.
  • the liner crushing member 12 or 32 is preferably a casting and is formed of a hard, wear-resistant material such as pearltic, carbidic, white cast iron; martensitic, carbidic, chromenickel alloyed cast iron, sometimes known as Nihard; or like materials having a Brinell hardness number at least as high as 400.
  • a hard, wear-resistant material such as pearltic, carbidic, white cast iron; martensitic, carbidic, chromenickel alloyed cast iron, sometimes known as Nihard; or like materials having a Brinell hardness number at least as high as 400.
  • the liner or 34 is positioned within a crusher bowl and mounted therein by suitable mounting means such as the hooks 14 or the mounting flange 54.
  • the bowl and liner surround a head adapted for gyratory motion.
  • a mantle is mounted on the head and is formed with an outer conical crushing surface, which, together with the inner conical crushing surface of the liner, defines a crushing cavity in which material is discharged from above for reduction.
  • the liner may be subjected to extreme stresses which tend to deform and/ or cause the active crushing portion and the mounting means of the liner to fracture or crack while the crushing surface may be subjected to extreme abrasive forces.
  • the choice of materials from which the active crushing element and mounting means is made has been limited, in accepted practice, to metals which have relatively poor wear characteristics, but which have a toughness which enables them to stand the stresses without breaking or cracking. It has been the generally accepted practice to cast the entire liner, including the active crushing portion and the mounting means, out of manganese steel.
  • manganese steel is tough and resistant to breaking and cracking, the crushing surface may wear away rapidly when crushing abrasive material. For example, in some crushing operations, the manganese steel liner may wear away at a rate of approximately one-eighth of an inch per three hour period.
  • hard, wear-resistant cast materials such as pearlitic, carbidic, white cast iron; martensitic, carbidic, chromenickel alloyed cast iron, sometimes known as Nihard; or the like which have a Brinell hardness number at least as high as 400.
  • the crushing member 12 or 36 is formed of a hard, wear-resistant material and the means for mounting the crushing member, such as the hooks 14 or the jacket 46, are formed of a tough, fracture-resistant material.
  • the mounting means may be secured to the liner crushing member by T-shaped feet 22 or 56 which are imbedded within the crushing member, by a surface bond between the mounting means and the crushing member, or by other suitable means.
  • the hooks 14 may be interconnected by tie-rods which are imbedded within the liner crushing member 12, so that during use in the cone crusher, should the crushing member 12 fracture, the hooks 14 will remain in supporting engagement therewith.
  • the tie-rods 24 additionally assist in maintaining the mounting hooks 14 properly spaced during casting and in maintaining any fractured segments of the liner crushing member 12 in Working position.
  • Such fractured segments of the liner crushing member 12 or 36 may be further maintained in working position by rings 30 imbedded or in cavities Within the cast liner crushing member as disclosed in US. Patent 3,473,746, issued Oct. 21, 1969. However, these rings may be omitted.
  • each liner mounting hook 14 or of the jacket 46 are such that the hooks or jacket may be firmly secured to the liner crushing member without having to be deeply imbedded. This enables optimum utilization of the material within the liner crushing member.
  • the crushing liner member may be made from a variety of hard, Wear-resistant materials.
  • a liner for use in a cone crusher said liner includa crushing member of truncated conical shape having an inner truncated conical crushing surface adapted to cooperate with a crusher mantle to form a crushing cavity and an outer truncated conical backing surface adapted to face an upper shell of a crusher, said crushing member being a hard, wear-resistant material, and
  • said mounting means being formed of tough, fracture-resistant material permanently secured to said crushing member and extending outwardly of said outer truncated conical backing surface.
  • mounting means comprise a plurality of circumferentially spaced, radially extending mounting hooks.
  • each hook is formed with at least one foot which is imbedded in said crushing member.
