Abstract

The screw conveyor with no overlap between two screw blades and the screw conveyor with large overlap between two screw blades were simulated by discrete element method and the distribution of particle axial velocity, angular velocity, forces around the shell and forces around screw blades was carried out. The results show that: the screw conveyor with no overlap between two screw blades has better performance, because its average axial velocity of particles and conveying capacity are larger, its mean angular velocity of particles and forces around screw blades and the shell are smaller and its power consumption is also less; Particles around the bottom of the shell and the edge of screw blades are more prone to be worn-out and break up; Forces around the bottom of the shell and the edge of screw blades are larger, so double screw conveyors will most probable be destroyed in these two positions. The above results can provide references for structures selection and optimal design of double screw conveyors.
