The ball mill abrasion test (BMAT) makes use of a conventional laboratory ball mill, which is a simple rotating barrel of similar geometry but smaller scale than typical industrial ball mills. ... In industrial ball mills, wear-resistant alloys are used not only for the grinding media but also for the replaceable liners which prevent damage to ...
Ball mill abrasion test (BMAT) High-stress abrasion can simply be produced in a laboratory ball mill, having similar geometry, motions, and interactions to those of industrial ball mills. It can be claimed that testing conditions exceedingly similar to service conditions can be achieved. Although it has not yet been standardised,
In the current work, the ball mill abrasion test (BMAT) has been used. ... In basalt, abrasion resistance increased linearly with Cr-CVF, at an average life improvement rate of 24% per 1% Cr-CVF. This confirms that performance is maximized by increasing Cr-CVF even in the presence of substantial volumes of cubic carbides.

Other investigators have observed similar behaviour. For example, Gates et al. (2008) have used ball mill abrasion tests (BMAT) to predict the relative service lives of wear-resistant alloys for grinding media in mineral grinding environments. The results showed that very hard (above 630 HV) martensitic steels and white cast irons only offer ...
The H/E ratio has been considered to be a valuable indicator in the assessment of the abrasion wear resistance of coatings. The wear resistance of Ti-based composite coatings, such as TiN-Al/TiN, TiN-AlTiN/SiN, and CrTiN-AlTiN-AlTiCrN/SiN, increases with the increasing H/E ratio, [ 175 ] which is consistent with above analyses.
