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. These solids can rapidly erode steel surfaces used in silos, hoppers, transfer chutes, screws or vibratory feeders. Abrasive Wear Tests Several tests can be performed to evaluate abrasive wear behavior. Sliding: evaluate abrasive wear with silos, hoppers, chutes with bulk material sliding along surface Impact: evaluate abrasive wear with hoppers or chutes where drop height or velocity causes damage For analyzing sliding wear, we use our patented wear tester with your abrasive bulk solids and representative process conditions.

Test Results The abrasive wear test results are presented in a thorough report which contains: overview of wear testing apparatus and experimental method results in graph and table formats qualitative observations of unique test phenomena conclusions and recommendations One of our engineers will review the abrasive wear test results with you. We will answer questions you may have regarding the report content, as well as discuss usage of the results for your abrasive wear applications. Need to send samples for testing?
