Abstract

The attachment of autoadhesive fine particles onto a large carrier particle in a vibrating container is investigated using a discrete element method (DEM) to determine the influence of the particle properties and vibration conditions. The contact number (number of fine particles contacting the carrier), coverage ratio (ratio of the contact number to that for complete monolayer coverage) and contact ratio (ratio of the contact number to the number of fine particles) are introduced to evaluate the attachment performance. The contact number increases with increasing work of adhesion, decreasing container size and increasing number of fine particles. The contact ratio decreases as the number of fine particles is increased. The coverage ratio increases as the carrier size is decreased.
