Packing of Fine Particles and its Relationship to Interparticle Forces

Abstract

This review describes the packing of powders, and ways to modify it according to practical needs. Packing is affected by the assembling procedure, the container form, the shape, rugosity, and size distribution of grains, the nature of forces at each contact, the ambient fluid and the external loads acting on the packing. The variety of powders properties required by concrete applications precludes the use of universal recipes for packing optimization valid for all of them. Therefore, in this report we discuss ideas and methods that can help engineers to solve their specific technical problems related to packing.
