MLPC ABROY Abrasion Meter

The test setup consists of a cylindrical steel sample container into which a steel vane is inserted. A mass of crushed rock (500 g in the grain size range of 4 to 6.3 mm) is placed in the container and the vane is rotated at 4,500 rpm for 5 minutes. The vane suffers abrasion and resulting loss of mass. The quantity of abraded vane metal is then correlated to rock abrasiveness.
