Saltation velocity is the speed below which particles being conveyed through a pneumatic conveying system lose suspension and begin to deposit at the bottom of horizontal pipelines.

In a dilute phase pneumatic conveying system, any particulate buildup at the bottom of the pipes can be problematic. This is why material characteristics, conveying rate, and system pressure are important considerations in dilute conveying.
Saltation velocity is basically the gas or air-conveying speed at which suspended particles being transported in a conveying system start to fall and deposit at the bottom of pipes or tubes. In order to prevent this, the minimum velocity in horizontal pipelines, also known as pick-up speed, is usually at least 20% higher than the saltation velocity.
Pneumatic pipelines can either be horizontal or vertical, but both of them need a minimum velocity in order to convey solids. While it’s necessary to check the saltation velocity (USALT) in horizontal pipelines, for vertical ones, it’s the choking velocity (UCH) you need to look out for.
