In the field of pneumatic conveying of bulk solids, typically a system design will be either Dilute Phase or Dense Phase, depending on the material’s specific physical characteristics and in some cases, the chemical composition can play a role as well. The definition of those two “modes” of conveying are often left to the equipment supplier to define or the views and opinions of independent research sources. To the end user, the various trade names, definitions, opinions and specific methodologies being employed by the equipment suppliers leads to confusion and in some cases misunderstanding of what is actually taking place inside the pneumatic conveying pipeline. This demonstration combined with a few slides will review the fundamental modes of pneumatic conveying and actually demonstrate them using an operating pneumatic conveying system model incorporating a 1 ½” diameter clear convey line so the material versus transport air dynamics can clearly be observed and easily understood. Some of the specific techniques used by the industry equipment suppliers of dense phase conveying systems will be discussed and demonstrated in a generic form.
