The Mechanical Research of Vertical Screw Conveyor Particle Group Based on the Radial Change of Material Speed

This paper establishes a granular mechanics model for the stable movement of material particle group in vertical screw unloader with mechanics, continuum and theory innovatively proposed hypothesis that speed changes radially spiral groove. Through analysis movement, characteristic parameters are determined. The study found free surface type longitudinal section conveyor its identification solution methods pressure distribution law on conveying pipe wall surface. In this paper, used to establish unloader. We groove determined through movement.
