Resumen
This paper presents the structural design of a belt feeder of an ore processing plant.
Particularly, the silos of this processing plant are subjected to a phenomenon that has been called avalanche: the liquefaction of a portion of the stocked ore when residence time and humidity exceed critical values and, then, when the flow control valve is opened, the ore flows uncontrollably through the subsequent equipment (the belt feeder is the first of these equipment).
To design the feeder to such exceptional situation, the designer adopted the criteria for determination of structural capacity by non-linear finite element analysis methods of the recommendation DNV-RP-C208:2013.
Safe and economic design of reticulate structures was possible but, it is highlighted an expressive weight reduction in boiler shop structures in comparison with more traditional design methods that apply linear elastic analyses.
