Pneumatic Conveying Methods. Utilizing air streams, either under pressure or in a vacuum, moves the materials. 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.

The velocity of conveying air was kept constant throughout the experiments, so the increasing mass flow rate of solids entails rising solids concentration and hence higher pressure drop. Furthermore, for a given mass flow rate of solids, a rising trend is observed in differential pressure with an increasing pipe angle because of the …

The conveying air velocity is the speed at which air circulates in the conveying pipe of a pneumatic conveying line. Air velocity is changing all along the conveying line following the pressure / temperature evolution, thus one must always refer to a reference position (beginning or end of the line) when calculating the air velocity.

The flexible tubular shape means pipe conveyors are able to overcome steep inclines and thus make transfer towers and power stations redundant. This is a key factor, especially in comparison to other conveyor belt systems. When a pipe conveyor has to traverse a downward incline, this motion can be used to efficiently recover energy.
