Types of Conveying Systems that are available
Pneumatic conveying systems can be qualified into three basic types of pipeline technologies. It is important to note that the distinguishing features of each are related to characteristics of product and air flow through the pipeline, without regard to the individual components which make up the total pneumatic conveying system. The three pipeline technologies and characteristics are:
Dilute Phase Conveying characterized by high velocity and low pressure with particles of the conveyed product in suspension in the air stream.
Dense Phase Conveying characterized by low velocity and high pressure with product being conveyed in slugs or plugs through the piping system.
Medium Phase Conveying characterized by velocities and pressure mid way between dilute and dense phase conveying with product moving through the pipeline in dilute phase technology above a settled "fluid or liquid" layer of product at the bottom of the pipe.
These conveying technologies are differentiated by three basic criteria. They are conveying velocity, operating pressure and material to air ratio (MAR). Material to air ratio is the mass relationship of product to air (normally pound per pound) in the conveying system.
