Pneumatic Conveying System | Technical Brief | Hapman

Dense phase conveying systems have a low air-to-material ratio. Velocities are below the saltation level, the critical velocity at which particles fall from suspension in the pipe. Dense phase systems, therefore, move the material through the piping in batches, with discrete dunes or plugs of material separated by pockets of air.

Lean Phase Vacuum Conveying | GEA Powder Handling

Vacuum Conveying - Dense Phase. Dense phase vacuum conveying systems use high capacity vacuum pumps (up to 99% vacuum) to convey materials from a feed hopper or silo to a receiving vessel or vacuum hopper where the air and product are separated by a filter. When the vessel is full, the vacuum is isolated and the conveyed product is discharged ...
