Whether the design is dense or dilute phase is not so important. It will be close to the minimum pressure drop per meter of length. Less air would make the conveying dense phase. mu in the table means the Soloid Loading Ratio (SLR) The free air delivery is already given in the calculation as: q-convey = 1.01 m3/sec # 60.6 m3/min

Dense phase system: This industrial air system is used to convey heavier materials that aren't in a powdered form, such as plastic pellets. Since the materials aren't suspended in air, this conveying system pushes the product through in waves and operates at a higher pressure and lower conveying velocity than dilute phase systems.

Lean Phase Conveying - Conveys material at high velocities and low pressure for energy efficiency. Dilute Phase Fluidized Bed Conveying - Suspends material in an upward airstream within a fluidized bed for improved mixing. Semi-Dense Phase Conveying - Uses moderate pressure and velocity for stable transport, reducing wear and degradation.

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 ...

Before discussing the methodology for selecting a dilute or dense phase conveying system, it is important to review the physics involved with transporting particles in a gas flow through a conveying line. Note that it is not the presence of a vacuum or pressure condition in a conveying system that imparts motion to the bulk solids, rather, it ...

Dense phase conveying utilizes a relatively low velocity motive gas, relying on a high pressure differential (either positive or negative) to move your bulk materials. Low velocity results in a gentle transfer, with materials moving with less wear and impact. This makes dense phase conveying ideal for most abrasive, fragile, friable, or even ...

Due to low conveying velocity, dense phase systems are often chosen for applications where the product is friable, abrasive or smears such as sand, glass, and coke. Most applications will benefit from low velocity, if not due to reduced wear, then due to reduced air consumption. As a general rule, the best economies are achieved by using the ...
