Using relationships described in (Gładysiewicz 2003), the nominal capacity of the conveyor
was defined at 457.24 kg/s. This value was accepted as the nominal belt load degree k z = 1.
The intensity of particle production in EDEM was increased by 25 kg/s at 10-second intervals (Fig. 8), in the range from 25 kg/s to 500 kg/s (Fig. 9). The capacity was measured at a
distance equal in length to the accepted idler set spacing (0.83 m) within the probing area.
As the DEM environment does not allow hyperelastic properties to be attributed to the
elements of the system, belt loads were exported to the FEM environment. In addition, the
Finite Element Method allows an analysis of material deformation resulting from the interaction between the material and the belt’s own mass. Therefore, belt loading was exported
from EDEM as force vectors (Fig. 10).
