This paper focuses on the methodology to calculate the effective reclaiming capacity of rail-mounted bucket wheel reclaimers, and stacker/reclaimers, for large-scale raw bulk material handling systems. Due to considerable gaps in the theory on this subject, a principal objective of the work presented here was to develop a methodology destined to determine reclaiming capacity of these machines. It reflects the relationship between the characteristics of the equipment and the parameters associated with its work environment. A function concerning the rule of the boom-slewing motion was defined. It was based on the particular shape of stockpiled material and the digging geometry of the machines. This function was subsequently employed as a basis to work out a precise methodology for calculating the effective reclaiming capacity of the equipment analysed. Successful validation of the model developed was performed for the Quebec Cartier Mining (QCM) port facilities in Port Cartier. The paper concludes with some possible applications of the results achieved in this study.
