Vinci Technologies | Versatile Attrition Tester
A sample of granular catalyst (or catalyst carrier, or adsorbent) is loaded in a cylindrical drum which is rotated around its axis for 30 min at a speed of 60 +/- 5 rpm. The fines produced by attrition and abrasion during the process are recovered by sieving the content of the drum with an ASTM N°20 sieve (aperture: 0.85 mm).

Bearing damage and failure analysis
as well as testing the bearing in the applica-tion, it sometimes happens that a bearing does not attain its required service life. Fail-ures will generally cause economic losses due to loss of production, consequential damage of adjacent parts, and the cost of repairs. Premature bearing failure can occur for a variety of reasons.
