Resistance Analysis for Bulk Materials in the Vertical Section of Pipe Scraper Conveyor

摘要

The conveying mechanism of the pipe scraper conveyor's vertical section is researched in detail by using the theory of granular media mechanics. It mainly analyses the packing and moving state, stress condition of the bulk materials in the vertical pipe, and deduces the relationship among the parameters of pressure distribution, running resistance of the bulk materials and structure, space and area of the scraper, deduces the calculation formula of running resistance in the vertical section of pipe scraper conveyor, then illustrates the effect of each parameter on the running resistance of bulk materials with living examples, whose purpose is to provide an effective reference for the design of such a pipe scraper conveyor.
