Dense Phase is the "powerhouse" solution for heavy, abrasive, or fragile materials. Unlike Lean Phase, it moves material at low velocities in "slugs" or "plugs," using high-pressure compressed air.
- Operation : Material is loaded into a pressure vessel (Transmitter), pressurized, and pushed through the pipeline as a dense column.
- Key Components : Pressure Vessels (Senders), Air Compressors, and specialized Flap Valves.
- Best For : Abrasive materials (Fly Ash, Sand, Cement), fragile crystals, and heavy minerals.
- Advantages : Extremely low pipe wear (due to low velocity), minimal material degradation, and the ability to convey over very long distances (up to 1km+).z
Technical Summary :
- Air Pressure : High (> 2 bar)
- Velocity : Low (1 - 10 m/s)
- Material-to-Air Ratio : High
- Pipe Wear : Minimal
- Power Source : Air Compressor
