ABSTRACT:
A jaw die assembly for the removeable and stationary jaws of a jaw crusher, the assembly is comprised of a stationary support grid, a center die section secured to said support grid and a pair of identical jaw die end sections, the jaw die end sections being supported on the support grid by interlocking engagement with the center die section and a jaw die extension. Besides having symmetrically identical jaw die end sections which are reversible and interchangeable, the center die section and grid assembly are also reversible, thus utilizing its wear surface area more completely. The center die section, end die sections and jaw die extensions are composed of austinetic manganese steel.
