Bulk solids theory has unique terminology, scientific flow principles that are not applicable to fluid or gas flow behaviors, and often has not been taught to engineers at the university level. Personnel responsible for designing, fabricating, installing, and operating bulk material handling equipment are often ill-prepared for the complex flow ...
Jan 01, 2016· Two types of flow patterns can occur when a bulk solid is discharged from a hopper, bin or silo: A typical funnel flow pattern is shown on the left, and a mass flow pattern is shown on the right
The term “bulk material” is used to refer to a granular or lumpy mixture existing in a free-flowing form. A bulk material’s properties are defined by its grain size and grain size distribution, as well as by its bulk density, angle of repose, moisture, and temperature. Bulk materials are classified into two groups:
These flow properties refer to the behav- ior of the bulk material and arise from the collective forces acting on individual par- ticles (e.g., van der Waals, electrostatic, surface tension, interlocking, friction). Rumpf and Podczeck provide more in- formation about underlying particle prop- erties that contribute to flow behavior (11,12).
When the flow of material gets stuck, shake it loose! For many years, the necessity to store material in bulk has created a problem - how to get it out of the storage vessel. Typical problems include …
the ability of powder to flow in a desired manner in a specific piece of equipment. With this definition,the term free flowing, so commonly used,becomes meaningless unless the specific equipment handling the material is specified. The specific bulk characteristics and properties of a powder that affect flow and that can in principle be measured are

Bulk material-handling professionals know that a steady material flow is vital to production and profitability – and, just as important, customer service. This consistency requires that chutes, bins, hoppers, silos and bunkers all be free of pluggage and material …
Many bulk materials increase in strength with time. This is a particular problem with the storage of bulk solids in hoppers and silos. A material stored for one day may well flow freely from a hopper but refuse to flow at all after being stored for two days. Bulk density can also increase with time, and significantly so with some materials.

The term “bulk material” is used to refer to a granular or lumpy mixture existing in a free-flowing form. A bulk material’s properties are defined by its grain size and grain size distribution, as well as by its bulk density, angle of repose, moisture, and temperature. Bulk materials are classified into two groups:
Whatever your bulk material characteristics - hydroscopic materials or powders, minerals, organic materials, fine or coarse granular particles - and whatever the bulk material handling equipment - bins silos, hoppers, bunkers, other storage vessels, …
