Beater wheel method

The impact test method simulates conditions involving combined impact and abrasive stress, allowing a wide range of materials to be tested. In this test, an abrasive material is brought into contact with rotating impact bodies and a fixed anvil (Figure 1). Both the impact elements and the anvil can be tested as specimens. During the test, the applied impact force can be recorded using a load cell. The mass flow rate of the abrasive material can be precisely adjusted with a tolerance of ±5 g/min and remains constant across the various test configurations.

The specimens are weighed before and after the test, and the material removal is reported in mg or, if the material density is known, in ^mm³. Depending on customer requirements, various materials can be used as abrasives.
