Abstract:
This paper presents the methodology defining key parameters of the stacking operation of rail-mounted bucket wheel stacker/reclaimers for raw bulk material handling systems. Due to gaps in the theory on this topic, the study aims at developing a mathematical model which characterizes the stacking operation of these machines. It integrates the relevant relationship between design characteristics of the equipment and the parameters associated with its work environment. The chevron, windrow and combined stacking methods are analysed and a mathematical model of the process is developed. The model is useful for a blending or homogenizing operation at a stockpile, as well as for automation of a stockpiling process. Furthermore, the model accurately defines operational parameters of this process which would enable an improved utilization of the machine and a better operation management. Successful validation of the developed model was performed for an operating iron ore mine.
