    dilute phase is probably the most common form of pneumatic conveying for this group of materials A much higher conveying line inlet air velocity must be maintained for dilute phase systems, even if the material is capable of being conveyed in dense phase Conveying line inlet air velocities are typically of the order of 2000 to 2400 ft/min for fine powders, 3000 to 3400 ft/min for granularDilute Phase Pneumatic Conveying The first and most common is the dilute phase system, which can be either pressure or vacuumfed These systems use high velocities to fluidize the product in the air/gas stream and use a higher ratio of air to product These systems have a number of applications including conveying long distances, batchweigh systems, or multiple pickup and discharge pointsPneumatic Conveying Systems 101: What Every ProjectDesign methods for dilute phase pneumatic conveying lines Shortcut calculation for sizing dilute phase conveying lines Do you have a question, a remark ?
