Liner for gyratory or conical crusher

Abstract

A concave for gyratory or conical crushers including a front face for providing a crushing surface and a top face proximate to the front face or adjacent to the front face. A first internal angle measured around a top front edge of the concave, and between the front face and the top face, is greater than 90 degrees. A liner is formed including a first concave and a second concave. The first concave is axially above and adjacent the second concave such that a top face of the second concave is substantially parallel to a bottom face of the first concave. The substantially parallel faces define a joining surface at an angle Y with respect to vertical. A front face of the first concave and a front face of the second concave are substantially parallel and define a surface having an angle M with respect to vertical, wherein M+Y>90 degrees.
