IMPACT TESTING OF MATERIALS FOR OIL SANDS PROCESSING APPLICATIONS

摘要

One of the main wear mechanisms experienced by materials in oil sands processing applications is material-loss due to impact. Components such as crushers, breakers and sizing screens can be subject to impact damage due to the presence of rocks and boulders. In the winter, the degree of impact damage can be increased, as sand and bitumen can consolidate into large agglomerates. In conjunction with Suncor Energy, the Alberta Research Council has designed and built a test rig to allow for the evaluation of a material’s resistance to repeated impact. This paper will describe the design of the rig and the associated test procedure. Results are presented for a range of materials, including tungsten carbidebased overlays, chromium carbide-based overlays and non-metallic materials.
