  • Patent number: 10500590
    Abstract: A gyratory crusher topshell and topshell assembly including an outer crushing shell and optional intermediate spacer ring. The topshell has a radially inward facing surface that is divided into a plurality of regions including an upper and lower mount region axially separated by an intermediate annular rib. The rib enables the topshell to be compatible with a variety of different sized and shaped concaves optionally using an intermediate spacer ring without the need for a backing compound.
    Type: Grant

  • Patent number: 10343172
    Abstract: A gyratory crusher includes an inner and an outer crushing shell. The outer crushing shell has three regions along its axial length including: an inlet region that tapers radially inward from an uppermost first end; a crushing region that extends radially inward from a second lowermost end; and a radially innermost shoulder region that is positioned axially between the inlet and crushing regions. An angle of inclination of a radially inward facing surface at the inlet and shoulder regions and the axial length of the crushing surface are designed to optimize crushing capacity in addition maximizing reduction.

  • Patent number: 9205427
    Abstract: A gyratory crusher outer crushing shell. The outer crushing shell comprises an upper contact surface region that is divided into a plurality of elongate circumferentially extending shoulders. The shoulders are separated by recessed gap regions adapted to accommodate a suitable backing material to structurally reinforce the shell. A channel extends circumferentially around the shell in the outward facing surface to axially separate the upper contact surface region from a lower contact surface region. The channel is also adapted to accommodate the backing material.
