Abrasive Wear Testing Capabilities Powder & Bulk Solids

Why Abrasive Wear Testing? Abrasive wear results when hard and often angular particles slide or impact against a softer surface. Wear of equipment can be a costly problem when storing and handling abrasive bulk materials such as iron ore, roofing granules, glass, alumina, fly ash, clinker, sand, and copper concentrate.get price

Chapter 9-Rolling Wear, Impact Wear, and Surface Fatigue

Therefore, rolling wear occurs by the nonuniform slip that accompanies a Hertzian contact. Impact wear is somewhat related. It is material loss/damage produced by a solid surface repeatedly impacting another solid surface. Hookean mechanics dictates that elastic deformation of surfaces occurs under impact. Plastic deformation can also occur.get price
