Basics of Pneumatic Conveying
Initially, straight horizontal conveying lines are considered again. Depending on the size of the conveying gas velocity (v_{F}), different flow states occur in the conveying line, see Fig. 4.3.With sufficiently high gas velocities (v_{F}), the solid flows through the conveying pipe relatively evenly distributed across its cross-section.Gradual reduction of (v_{F}) …
