The improved diamond dynamic loading tester draws the following conclusions: The broken energy given by the waveform chart print, which is measured from the original loading tester, is a r

The improved dynamic loading tester can display the test result directly on the computer through the digital interface, such as the absolute broken energy value for crushing the diamond, the peak impact force, effectively crushing time, etc. It also can obtain the diamond grit broken
10、energy under the different hammer drop-height by adjusting the distance from the top of the impact-bearing bar to the anvil.,5,In order to verify the reliability of the energy-absorbing device, we make the hammer to drop from various heights and impact the same diamond sample. Then we compare the impact fracture force F getting from the various experiments. The diamond grits used in the experiments are synthetic diamond in grain size 50 US mesh. The drop-height of hammer varies from 10, 15, 20 and 25 mm.,Put Your Logo Here,
