This paper focuses on the reconstruction of the process scheme to solve the problems that the current process scheme of a port on the Yangtze River for bulk cargo loading causes environmental pollution，high energy consumption，and heavy yard and wharf surface wear. By designing a bucket-wheel stacker-reclaimer with a retractable tripper car and a discharging conveyor with an extension header，the paper enables material feeding and discharging and material sorting at the same side of the yard. It also achieves material feeding and loading at both sides of the yard by adopting a scheme of a mobile ship loader with a tripper car on both its left and right sides and a two-way conveyor. The flow-oriented reconstruction of the loading process and the utilization of the outer-rotor permanent-magnet direct-drive roller enables the project under discussion to achieve the expected effects of environmental protection and energy saving.
