摘要： 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.

摘要： 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.

摘要： 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.
