The utility model relates to testing equipment, in particular to devices for testing metals and alloys, as well as composite materials and coatings for resistance to abrasive wear at low, normal and elevated temperatures. The installation for testing materials for abrasive wear contains a frame on which a drive for rotation of the samples and a mechanism for their rotation are located. The center of the circle of rotation of each sample is displaced by ½ of the sample diameter due to the difference in the lengths of the arms of the cross, which ensures uniform mixing and renewal of the abrasive mass and uniform wear of the samples.
