Abstract EN
By using numerical code RFP A 2 D (dynamic version), numerical model is built to investigate the failure process of rock particle under impact loading, and the influence of different impact loading on crushing effect and consumed energy of rock particle sample is analyzed.
Numerical results indicate that crushing effect is good when the stress wave amplitude is close to the dynamic strength of rock; it is difficult for rock particle to be broken under too low stress wave amplitude; on the other hand, when stress wave amplitude is too high, excessive fine particle is produced, and crushing effect is not very good on the whole, and more crushing energy is consumed.
Secondly, in order to obtain good crushing effect, it should be avoided that wavelength of impact load be too short.
Therefore, it is inappropriate to choose impact rusher with too high power and too fast impact frequency for ore particle.
