Lean (Dilute)
Lean or dilute phase vacuum conveying systems generally use positive displacement exhausters to provide a vacuum (up to 50%) to convey materials through a pipeline to receiving vessel where the air and product are filtered and separated. Lower capacity fan-based systems are also available.
Convey Rates: | < 10 tonnes/h. |
Convey Distances: | up to 100 m |
Air mover: | positive displacement (Roots Type) exhauster or fan |
Operating Pressure: | <50% vacuum |
Air Ratios: | low to medium |
Dense phase pressure conveying systems use compressed air to push materials from a single or twin pressure pot system through a pipeline to a destination where the air and product are separated.
Lean or dilute phase pressure conveying systems use positive displacement blowers —providing air at up to 0.6 Barg — to convey materials through a pipeline to a destination where the air and product are separated by a filter.
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 into the destination silo. The prod...
