| Popis: | In this experimental study, behavior of dry granular layers of monodisperse cylindrical particles (8 × 1 mm) under uniaxial compression in piston die arrangement was investigated. The layer compressibility and particle size distribution (PSD) were measured. It was found that neither the piston speed nor the layer size were relevant, within the experimental range. The compressibility and PSD were affected mainly by the applied load. At the single compression, with the increasing pressure, PSD moves toward smaller sizes of broken particles always leaving some initial particles intact. At the repetitive compression, the pressure had more destructive effect, resulting in larger particle fragmentation. |
