Pneumatic conveying systems are used to transfer powders, granules, and other dry bulk materials through an enclosed pipeline. The motive force for this transfer comes from a combination of pressure differential and the flow of a gas, such as air or nitrogen. Positive displacement blowers generate pressurized or vacuum air to provide the

Dilute phase also refers to the lean solids loading within the conveying line. Typically, a dilute phase line conveys less than 15 lb (~7 kg) of solids per pound (~0.5 kg) of gas at a pressure of less than 15 psig (~1 barg). Dense phase. This occurs when particles are conveyed in the gas stream at a velocity that is less than the saltation

· Low-pressure dilute phase systems use an entry air pressure under 15 psig to move materials through the conveying line at a high velocity while suspended in the air stream. But high-pressure dense phase systems use smaller amounts of high-pressure air of 15-50 psig to move material through the line at a low velocity as slugs.

Three primary categories of pneumatic conveying methods exist: dilute phase, dense phase, and air conveying. These methods function based on specific velocities, pressures, and air-to-product ratios within the system. Dilute phase conveying is a continuous, high-velocity, low pressure and high air to product loading ratio process.

What a Pneumatic Conveying System is. The principle of pneumatic conveying is based on the fact that bulk goods can be moved by means of air through pipelines. The flowing conveying air transmits a propulsion force on the bulk material and thus conveys it through the conveying line. The pneumatic conveying always requires a pressure difference
