Conveying Systems at a Glance

Pneumatic conveying is the transport of bulk solids through a pipe by using the flow of air or other gas.

Typical bulk materials pneumatically conveyed are powders, pellets, granules and irregularly shaped particles smaller than 20 mm [0.75 in]. The majority of pneumatically transported materials have a bulk density between 0.1 to 1 kg/dm3 [5 to 100 lb/ft3].

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]. Dilute phase conveying systems will work reliable for a wide range of materials with different characteristics, such as high bulk density, cohesive properties or extreme particle shapes. Due to the high air velocity material degradation or wear might appear.

There are various dense phase conveying methods available that gently convey a specific bulk material and therefore reduce the risk of material degradation and wear. In many cases, a dense phase pneumatic conveying system offers a higher quality end product which offers greater value to the user at the final destination.
