Dense-Phase Pneumatic Conveying Systems | Powder/Bulk Solids

Jan 11, 2007· The two main categories of pneumatic conveying technologies are low-pressure (dilute-phase) and high-pressure (dense-phase) systems. Utilizing air pressure under 15 psig, the first category uses either positive or negative pressure to push or pull material through the convey line at relatively high velocities (see Figure 1).

Dense Phase Conveying for Bulk Materials | Nol-Tec

Dense phase pneumatic conveying involves the transfer of powders, granules, and other dry bulk materials through an enclosed pipeline. In dense phase conveying, particles are not suspended in the conveying air and are transported at high pressure and low velocity. This results in a more gentle delivery process for the products being conveyed.
