ball mills are common grinding equipment in mineral processing industries. ball wear results from three mechanisms namely impact, abrasion and corrosion. of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. therefore, the aims of this research were to investigate the grinding chemistry influence (slurry ph, solid percentage, water chemistry an...

The research focuses on slurry abrasion and erosion of martensitic steels used in the mining agricultural industries. A traditionally constructed pot tester with corundum abrasives form was for wear characterisation. Wear testing performed each specimen 180 h. Every 20 h, pauses were taken to characterise size, weight, hardness, surface roughness. worn zone’s damage progression studied using op...

Abstract Abrasive wear mechanisms—including two-body and three-body abrasion—dominate the performance lifespan of tribological systems in many engineering fields, even those operating lubricated conditions. Bearing steel (100Cr6) pins discs a flat-on-flat contact were utilized experiments together with 5 13 µm Al 2 O 3 -based slurries as interfacial media to shed light on acting mechanisms. The...

Abstract The simulation and corrosion conduction of anti-acid brick in high temperature particle abrasion circumstances were tested with scanning electron microscopic, mechanical compression, X-ray diffraction. results showed the strength degradation rates Anti-acid 7.0% 17.8% different high-temperature acid conditions. water vapor environment permeated into after eroding crystal structure surf...

This paper develops analytically a statistical model for predicting the material removal in mechanical polishing of material surfaces (MS). The model was based on the statistical theory and the abrasive–MS contact mechanisms. The pad-MS and pad-abrasive-MS interactions in polishing were characterised by contact mechanics. Two types of active abrasive particles in the polishing system were consi...

Abrasive wear behaviour of WC-Co and Fe/Cu-based nanostructured coatings has been investigated under dry slurry conditions in this study. The retention coating constituents was confirmed together with the formation various metallic ceramic phases. rate one order lower than that micro-structured both conditions. Relatively higher abrasion resistance such compare to reference material because com...

The impeller blades of ceramic slurry pumps are usually very thick for the purpose prolonging service life. In this paper, numerical simulations and wear test were conducted to investigate influence blade thickness on solid–liquid two-phase flow in a centrifugal pump. was CFD validation. results show that incident angles solid particles increase with increasing thickness, which larger wrap part...
