Pneumatic Conveying Systems

Pneumatic transportation can be built as a pressure or vacuum system. The most commonly applied pneumatic conveying mode is dilute phase conveying where particles are airborne. Depending on the size, shape and weight of the particles, the gas velocity will range from 4 to 40 m/s [4,000 to 8,000 ft/min].
