The Bond Abrasion Index, devised by F.C. Bond in the 1940‘s, quantifies the abrasivity of ores and minerals. The index serves to calculate metal wear rates in crushers and ball consumption rates in ball mills.

The AT 100 XL consists of a rotating insert into which dry ore samples with a defined particle size are placed. An impact paddle mounted on a centre shaft, rotating at a higher speed than the insert, grinds the sample over a defined period of time.

Both insert and paddle rotate in the same direction. The paddle is made from standard alloy steel hardened to 500 Brinell. The Abrasion Index is calculated from the weight loss of the paddle under standard operating conditions.
