主 题：Screw conveyor Drum Axial tilt angle Conveying performance DEM
摘 要：Screw conveyors are widely employed in industrial fields for conveying bulk *** shearer drum which uses the screw conveying principle is responsible for excavation and conveying coal particles onto the chain *** conveyor performance is affected by potential factors,such as the blade axial tilt angle and style,core shaft form and *** effect of blade axial tilt angle on the conveying performance was investigated with the help of *** the case of the screw conveyor,the mass flow rate,and particle axial velocity increased with increasing positive axial tilt angle,and declined with increasing negative axial tilt *** the case of the drum,the mass flow rate,particle axial velocity,and loading rate first increased and then decreased with increasing positive axial tilt angle,and decreased with increasing negative axial tilt *** results can be considered as a benchmark for screw conveyor and drum structural designs with axial tilt screw blades.
