##tihuan2##1. Definition What is the minimum air conveying velocity for a pneumatic conveying system ? In order to transport a solids in dilute phase (coarse solids like pellets or powder), the conveying air must reach a threshold value called the mininum air conveying velocity. If the air velocity is below this value, the solids will ultimately settled at the …
