Introduction
Dense Phase Pneumatic Conveying System for Cement and Fly Ash
Dense Phase Pneumatic Conveying System
Dense phase pneumatic conveying moves bulk materials through pipelines at low velocity (3-8 m/s) and high pressure (1.5-4 bar), using compressed air to push material in plug or fluidized form. Compared to dilute phase systems, dense phase reduces energy consumption by 40% and pipe wear by 60%, making it the preferred choice for abrasive materials like cement, fly ash, and slag.
How It Works
Material enters a pressure vessel (sender pot) through an inlet valve. Once filled, the vessel is pressurized with compressed air. A controlled air injection sequence pushes the material through the pipeline in dense plugs or a fluidized column. At the receiving end, a filter vent releases the conveying air while the material enters the destination silo or hopper.
Key Advantages
- Low velocity: 3-8 m/s vs. 15-30 m/s for dilute phase → dramatically reduced pipe wear
- Low energy: 0.8-1.5 kWh per tonne per 100m vs. 2-4 for dilute phase
- Minimal degradation: Gentle handling preserves particle integrity
- Long distance: Effective conveying distances up to 500m+ with boosters
