FIELD: testing of materials. SUBSTANCE: rotor with tested samples is installed inside vessel with abrasive fractions from 5.0 to 60.0 mm. Machine also has drive of rotor and lever gear to control pressure of abrasive material on tested samples which are positioned on rotor at angle exceeding angle of natural slope of movement of dust-like products of abrasive wear. EFFECT: simplified design, enhanced reliability of testing.
