Introduction. The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Softer ores, such as placer deposits of tin, gold, mineral sands, etc., do not require such a treatment. ... For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape ...
This would mean they would need regular maintenance and replacement. If you want to crush lots of hard rock you would need a heavy-duty machine such as the Omega J1065T jaw crusher or Rockster R900 impact crusher. Most jaw crushers will crush soft rock quickly and easily. The ARK 704 jaw crusher would be a perfect

The purpose of this paper is to select a suitable candidate material for the design of crusher jaw that can sustain fracture by any of the three modes of failure – tear, shear and impact at low cost using CES EduPack. The CES material and process selection software is an example of such a computer implementation (Ashby, 2005).
