  • Patent number: 10189024
    Abstract: A gyratory crusher frame part and a gyratory crusher include a topshell and spider assembly configured to minimize stress concentrations. An annular flange is formed at the junction between a lower region of each spider arm and an upper region of the topshell. Optimization of loading force transfer and a reduction in stress concentration is achieved by positioning the spider arms radially inward relative to an outer circumferential perimeter of the flange.

  • Patent number: 10179335
    Abstract: A crusher wear resistant liner for positioning at a crusher bottom shell includes a plurality of modular wear resistant plates mountable at an inside surface of the bottom shell and positioned side-by-side to surround and protect the bottom shell interior. To prevent independent dislodgement of each plate and liner, respective inter-engaging formations are provided at each plate to contact at least one adjacent plate of the assembly to arrest any unintentional downward movement in the event that the primary fixings become ineffective.

  • Patent number: 10173221
    Abstract: A gyratory crusher crushing head, removably mounted a crushing shell, includes a circumferential groove is formed in an outer facing surface of the crushing head. The groove is positioned towards a second lower end at the outward facing surface relative to an axial length of the crushing head. The groove and its relative axial positioning minimizes the stress concentrations at the crushing head resulting from forces tangential to the outward facing surface.

  • Patent number: 9827569
    Abstract: A gyratory crusher frame part includes a topshell mountable on a bottom shell, the topshell having an annular wall extending around a longitudinal axis. A spider having a plurality of arms extending radially outward from a cap is positioned at the longitudinal axis. Each arm has a first portion extending in a radially outward direction from the cap and a second portion extending in an axial direction from an outer region of the first portion. An annular flange is positioned between the second portion of each arm and the annular wall. The annular wall is defined between an outward and inward facing surface of the annular wall. A section of the wall neighboring the flange includes a concave section at the outward facing surface. A first half of the concave section closest to the flange is a substantially uniform curve extending continuously in the circumferential direction around the longitudinal axis.

  • Patent number: 9827568
    Abstract: A gyratory crusher main shaft sleeve friction fit over an uppermost end of a crusher main shaft. The sleeve includes an elongate axial wall for being positioned in contact with an outward facing surface of the main shaft. The axial wall has a thickness that decreases in a direction from a second upper end to a first lower end, wherein the internal facing surface of the sleeve extends transverse to a longitudinal axis of the sleeve so as to taper inwardly towards the axis in a direction from the first to the second end.

  • Publication number: 20160271614
    Abstract: A gyratory crusher main shaft assembly has a main shaft, an axially upper region of the main shaft including a tapered conical section with a protective sleeve friction fitted over the cone. To facilitate mounting and dismounting of the sleeve, at least one groove is indented within a radially external facing surface of the main shaft at the region of the cone to allow fluid to be introduced under pressure to the region between the sleeve and the cone.

  • Publication number: 20160236198
    Abstract: A gyratory crusher bottom shell and/or bottom shell assembly include protective liners that are mounted over and about respective support arms that extend radially between the bottom shell wall and a central hub. The support arms have a seat or saddle region with at least a part of the liner positioned in contact with and supported by the seat to distribute the mass of the liner radially between the hub and the shell wall and to reduce tension in the primary attachment bolts.
