ABSTRACT:
A segmented wear resistant band for protecting a surface subject to wear in a crusher is comprised of segments or concaves. The segments of the wear resistant band can be separated from each other by portions of reduced thickness. The portions of reduced thickness can be cut after the installation to the surface. The segments can also include a flange for reception in a recess between a spider and the top shell of a gyratory crusher.
