Mining and mineral processing demand wear-resistant machines and components, because the energies and masses of interacting bodies are significant. This paper is concerned with the wear mechanisms, which occur in grinding mills. Conditions of severe-impact wear and impactabrasion, and wear behaviour of the lifter bars are studied. A hammer-mill type device, …
