Methods for assessing abrasive properties of rocks are fairly numerous, but, so far, there exists no universal and generally accepted one. At the basis of most methods lies the measurement of the volume or mass of the metal worn out during friction against the rock under certain conditions constant for a given method. Among laboratory procedures, the one proposed by Prof. L. A. Shreyner is most suitable for appraising abrasiveness of rocks. In essence it consists in that a reference ring made of test material (steel, hard alloy), tightly pressed with its lateral cylindrical surface against the horizontal ground surface of a test rock sample under the action of a pre-set force, revolves about the horizontal axis at a constant speed. The rock
sample advances relative to the ring at a certain pre-assigned speed. Disintegration products resulting from the friction of the ring against the rock surface are carried away by a jet of water supplied to the site of the, contact. The abrasive properties are judged by the volume of the broken down material of the ring and rock along the friction route of 1 m.
