Wear affects almost all solid materials. In material handling applications, wear progressively removes material from solid surfaces by relative motion between contacting surfaces or by particle-laden flow streams, as in pneumatic conveying. While wear can shorten the life of almost anything, its effects on handling equipment — particularly equipment that handles abrasives — are even more dramatic.
Alumina ceramic: A material for reducing equipment wear
This article discusses alumina ceramic, an alumina- based ceramic material that's used as a wear- resistant liner in equipment that handles abrasives. General information about wear and wear-resistant materials is given, and the qualities of alumina ceramic are compared to those of other wear- resistant materials. Design factors to consider when using alumina ceramic for lining handling equipment are also discussed.
