While the dilute phase has air ...

Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream. The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed. The velocity is typically set between 400 ft./min. and 1,000 ft./min., though there are several forms of dense ...

Dense Phase is typical used to convey abrasive, fragile and friable material long or short distances.

Dense-Phase Pneumatic Conveying Systems. Pneumatic conveying is achieved by creating a pressure differential along a pipeline and using the air that moves toward the area of lower pressure to move bulk material. This process can be performed with a vacuum inducer or by injecting compressed air into one end of a pipeline or along the pipeline.

Dense phase pneumatic conveying is less common than comparable dilute phase because of the greater capital investment involved, if there is no need to be concerned about breakage or wear. Dense phase systems are more commonly powered by higher pressure (~100 PSIG) and higher horsepower air compressions, making them more costly to operate so it ...

Dense-phase conveying. This occurs when particles are conveyed in the gas stream at a velocity that’s less than the saltation velocity. Two general modes of flow can result in dense phase and are referred to as plug or piston-flow and moving-bed (dune) flow. Only certain bulk solids can be efficiently conveyed in these two dense-phase modes.
