Properties
POM
Glass
Particle mass [kg]
0.75
~1.41
Liquid amount [%]
0/5/10
0/2.5/5
Surface tension [N/m]
0.07275
Aperture size [mm]
8.00 ± 0.02/5.60 ± 0.01
Wire diameter [mm]
2.00 ± 0.01/1.60 ± 0.01
Scree wire profile [−]
Circular (woven)
Set amplitude [mm]
1/0.8
Frequency [Hz]
~50.6
Stroke behavior
Elliptical, mainly vertical
amounts in the range of 0% ≤ M ≤ 10% are applied. In the case of glass spheres,
the percentage amount is lower in order to maintain a pendular regime. Mechanical
and physical particle and wall properties are presented in Table 7. Distilled water is
use as a liquid.
In Table 8 the DEM parameters coulomb friction μ c , rolling friction μ roll and the
coefficient of restitution e
n for POM and glass spheres with their respective contact
partners are listed. Details according their determination can be found in [30].
