SEGREGATION OF NON-SPHERICAL PARTICLES IN A VIBRATED BED USING DEM

Abstract

In particle science and technology, granular materials are studied both at the micro- and macroscopic levels. Granular materials 1.1 are ubiquitous in the industry, yet their behavior is not well understood. The macroscopic behavior of the granular flows is influenced by the interaction between particles and the surrounding fluids. Non-spherical particles play an important role in industrial operations, as we will discuss in this article. In industries such as food, pharmaceuticals, cement and mining, non-spherical particles comprise at least 70% of the particles used in industrial operations. These materials are present in various forms, such as tablets, catalyst pellets, powder, grains, plastic, salt, and sugar. They are typically used in many industrial processes mentioned in figure 1.2 such as drying, blending, granulation, pneumatic conveying and fluidization.
