Dense Phase Pneumatic Conveying System
A Dense phase pneumatic conveying system transfers bulk materials at
low velocity (2–10 m/s) and high pressure (1–6 bar (g)) using
compressed air. The material moves in the form of plugs or
dunes, ensuring controlled and gentle conveying. This method
significantly reduces product degradation and minimizes
pipeline wear, making it ideal for long-distance transport of
powders, granules, and flakes—especially for fragile or abrasive
materials.
