Simulation and Analysis of Attitude of Non-Spherical Particles in Drum Granulation

Abstract

The process of drum granulation is forming agglomerate by infiltrating liquid or binder into solid fine powder to produce bond force. Seed particles present different shapes features in granulation process. Different shapes of particles will have different movement trajectory and attitude under the condition of different location or rotational speed in the cylinder. The motion pose of different shape particles are analyzed by the simulation method using discrete element method, this way is better for us to control the time of powder in different drum position and frequency of adding powders per time. Research provides the theoretical basis on regulatory means and control parameters for adding powders and guarantee the production efficiency.
