Dynamic Air Inc., a major leader in the dense phase pneumatic conveying industry, is a specialist in the pneumatic conveying of dry, bulk solids. Applications range from food to poison, from light fumed silica to heavy powdered metals. However, all of these applications have one thing in common, the necessity to control the conveying velocity in order to control particle degradation, conveying pipe wear, minimize air consumption, or eliminate pipe line plugging. What is Pneumatic Conveying? Pneumatic conveying is nothing more than creating a pressure differential along a pipeline and moving a bulk material along with the air as the air moves towards the area of lower pressure. This can be done with a vacuum inducer, or with compressed air being injected into one end of or along the pipeline. Dilute Phase vs. Dense Phase Pneumatic Conveying The two most distinct categories of pneumatic conveying can be described as either low pressure (dilute phase) or high pressure (dense phase) systems.
