ABSTRACT

Screw conveyor is a major equipment for bulk delivery and the vertical screw conveyor is one of its key components. Research on the vertical-screw conveyor helps to optimize the design and increase the efficiency of bulk transportation. The theory of Bulk Mechanics, analysis tool (EDEM) with discrete element and a setting periodic boundary model are applied in this work to simulate the vertical screw conveyor’s grain (e.g., coal) delivery condition under different fill levels and screw rotational speeds and analyze the conveying process, state, and performance of bulk materials in the vertical conveying of the screw ship unloader under different filling rates and speeds.
