A typical pneumatic conveying system transfers granules, powders, and other dry bulk materials with the help of a closed vertical or horizontal conveying line. The force required for the transfer of materials is extracted from a combination of pressure differential and the flow of air (or other gas) supplied by a blower or fan. The system can transport materials by regulating the pressure or vacuum, and the airflow in the conveying line. There are three main categories of pneumatic conveying systems , which are dilute-phase, dense-phase, and air conveying. Dilute-phase conveying process includes pulling or pushing materials from one place to another by maintaining an adequate airstream velocity. Dilute-phase conveying system is a continuous process, and described by low pressure, high velocity, and low product to air ratio. Dense-phase conveying type relies on a beat of an air to force a pellet of material from one location to other. Dense-phase system is a batch process, and unl...
