Influence of processing factors on metal consumption of receiving hopper of crushing-and-transfer facility

The article discusses the influence of processing factors on metal consumption of receiving hoppers of crushing-and-transfer facilities in open pit mining. Spotlight is on loads generated during hopper operation, including static loads from rocks and dynamic loads from impact of coarse ore. The scope of the analysis embraces effects exerted by mass and fall height of ore, total mass of ore loaded in the hopper, and by some other geometrical parameters on metal consumption of the hopper structure. The calculations show that impact loads exerted by falling ore have the determining influence on the hopper structure at the length of the beams up to 19–20 m, while at the longer beams, the static loads applied by ore on the hopper prevail. It is taken into account how the change of the length and width of the hopper influences loading dynamics, including the decrease of the dynamic impact load factor for the long beams. Relations and their analysis in the context of the design practices are presented. The strength calculations by analytical methods are described. The dynamic load was calculated in terms of the dynamic factor. The research findings allow optimizing hopper design parameters with a view to reducing metal consumption at the same strength and reliability of the structure, at zero inefficiency and with the decreased hours of calculations.
