This machine is for determining the resistance to wear off small size coarse aggregates and crushed rock.
The Machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. A detachable shelf which extends throughout the inside length of the drum catches the abrasive charge and does not allow it to fall on the cover.

The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive powder, revolving at the rate of 30 +/- 1 rpm. At the end of 100 revolutions of the disc, the second parallel side of the tile is subjected to wear an equal number of revolutions of the disc.
The abrasion testing machine consists of a replaceable grinding path, fitted on to a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counterbalanced lever.
Supplied complete with automatic pre-set revolution counter and one 7.5 kg weight.
Suitable for operation on 415V, 50 Hz, 3 phase, AC supply.
