ROCKY DEM Simulations of Pipe Belt Transitions |
 |
Cross section looking from the tail end of a pipe conveyor. The pipe belt is transitioning from trough shape to pipe shape, while the material follows the transition. |
 |
The effect of the pipe transition and material adhesion causes the initial V shape seen in this material cross section. |
 |
The moving belt eventually settles the material to a more conventional shape. |
|
Finite Element Analysis (FEA) Models of Curved Pipe Belts |
 |
Cross sectional image of a 200 mm diameter pipe Finite Element Analysis (FEA) model, with steel cord and fabric in the belt. |
 |
FEA model of a pipe going through a horizontal curve, which causes distortions in pipe shape, and loss of contact with side idler rolls. |
|
Confine™ Pipe Belt vs. Conventional Pipe Belt |
 |
Cross section of a conventional 500mm diameter ST4000 pipe belt at a 500 mm radius horizontal curve. |
 |
Cross section of a Confine belt with the same rating, stiffness, tension and horizontal curve radius as the conventional belt above. The Confine belt performs much better around curves. |
 |
Histogram comparison of a conventional belt (black columns) and a Confine belt (red columns) with the same belt stiffness.
The Confine belt has higher pressure on the upper three idler rolls and lower peak pressure on the bottom three rolls. |
