Compared to other commonly used principles such as dilute phase or overpressure conveying, this technology offers valuable advantages.

The transfer of dense phase powders allows, among other things:

• not to create any de-mixing of the powders

• not to generate electrostatic charges (transfer speed from 3 to 8 ms-1)

• not to use ambient air as a vector

• not to create attrition of the transferred powders

• to work in total containment

• to be energy efficient
