Pneumatic Conveying

Pneumatic Conveying Using compressed gas (air) and/or vacuum to move bulk materials such as granules and powders is called pneumatic conveying.  Whether a dilute phase, dense phase or other type of pneumatic conveying system, producers know that pneumatic conveyance is the life blood of their plant.  This is why the cement industry has relied on Ro-Flo compressors and vacuum pumps as the heart of their pneumatic conveying systems for over 40 years. Dilute Phase (Lean Phase) Conveying Arguably, the most the common type of pneumatic conveying is referred to as dilute or lean phase conveying.  It is also frequently referred to as suspension flow.  This type of pneumatic conveying can be characterized by lower pressures, higher velocities and a low ratio of product to air in the conveying stream.  Dilute-phase conveying can be done with positive pressure or vacuum pressure. Dense Phase Conveying Contrary to dilute phase conveying, dense phase conveying is characterized by higher pressures, lower velocities and a high ratio of product to air in the conveying stream.  Dense-phase conveying is done with positive pressure where pulses of air will push slugs of material in succession along the conveying stream. There are other methods of pneumatic conveying, such as air-activated gravity conveying, and one can also have combinations of pneumatic conveying such as medium phase pneumatic conveying.  However, all types of pneumatic conveying rely on a compressor and/or vacuum pump.  Ro-Flo compressors and vacuum pumps are designed to handle all types of pneumatic conveying.  Their model configurations and variable speed capability ensure that the highest efficiency is maintained. Ro-Flo’s pneumatic conveying applications include product transfer, railcar unloading, mixing, bulk storage and dispensing, to name a few.  Ro-Flo’s can be used in conjunction with dry material injection pumps.  Pneumatic Conveying Systems are used in many industries such as mining, [...]
