Effect of stem crushing on the uniaxial bulk compression ...

2018-11-1 · The effects of crushing on the wet bulk density were of interest because this value directly effects the mass of material that could be loaded on a truck. As expected, the pressure required to achieve the target wet bulk density was much lower than the pressure required to reach a bulk density of 256 dry kg m −3 .

2007-8-21 · [32] When pore collapse and grain crushing take place (at P = P*), the crack density ρ raises from 0 to a mean value of 0.1 (curve 3). An anomalous feature just beyond P * is that crack densities inferred from equations (8) and (9) become different: Inversion of G moduli gives a ρ value close to 0.2, whereas inversion of K moduli data gives a ...
