In engineering operation, erosion of solids is a factor that cannot be ignored as it reduces the life and efficiency of machine and tool. Quantitative measurement of this wear is needed to study its law and to combat it. The authoers designed a hexagnal device for testing solid erosion and analysed its working principle and wear mechanism A lot of tests were made to study the effects of operating parameters of the tester, such as solid size, solid content and solid impact rate. Based on this a testing standard is presented Erosive wear of various rock grains was measured with this standard. Conclusions can be drawn from all the work that the hexagnal device is portable and easy-handling. It has minimum measuring error and good repeatability, and can be used as a tool for testing solid erosion. The tester application can also be expanded by adjusting operation parameters or/ and by changing testing materials to measure solid wear under different conditions and wear resistance of various materials.
