Study on the Variation Characteristics of the Average Velocity of Special-Shaped Flake Particle Systems Moving in Elliptical Drums

Researching the moving speed of particles in a drum is helpful to optimal design rotating device. In this paper, average mixing velocity flake with different shapes an elliptical studied. detail, systems rectangular, triangular, and circular are studied; rollers eccentricities periodic variation characteristics particle system at 15 rpm 45 compared analyzed; curves velocity, peak fitting curve (PFC), trough (TFC), under various working conditions drawn. The results show that fluctuation range increases gradually increase eccentricity device volume particles; PFC has certain cycle, while above two rotary almost no cycle.
