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.
