Abstract

This article presents methods for measuring fundamental bulk solids flow properties and explains how to use them to design hoppers, bins, and silos for reliable flow. It expands to solids storage and handling and bin design by providing a step-by-step guide to the graphical analyses and calculations necessary for bin design. An example calculation section illustrates how to specify storage vessel shapes, outlet sizes, and hopper angles. The first step in the design process is to determine the fundamental properties needed to predict the flow behavior of bulk solids: cohesive strength, internal friction, compressibility, wall friction, and permeability. Test results are used to calculate the size of the hopper section outlet and the recommended hopper angle. The properties are determined by calculations, measurements, and graphical analysis.
