Rock Abrasiveness Apparatus

The Rock Abrasiveness Apparatus is used for measurement of rock abrasiveness under the standards specified by the Cerchar test. The test consists of measuring the wear flat on the standard steel indenter with 200 kg/mm2 hardness loaded with 70 N force, after it has scratched 10 mm distance on the rock surface. The indenter is examined under the microscope and the amount of wear is correlated to the Cerchar Abrasiveness Index (CAI).
