AWE's Pneumatic Conveying Systems are Custom Designed for Dilute or Dense Phase Transporting of Powders & Granules.
Dense Phase
The basic concept of Dense Phase Conveying is that a pulse of air is used to force a plug of material from one point to another. The air has high pressure and low velocity. It is ideal for Higher density products or conveying longer distances. Dense phase is the best option for abrasive & pre blended products.
Dense Phase Systems can be further divided into 2 main types:
1. Dense Phase Pressure
The system uses a vessel to hold the material while air is injected to a set pressure. The discharge valve is opened sending a plug of material to the destination. A filter at the destination cleans the exhaust air. Most Dense Phase systems are of this type.
2. Dense Phase Vacuum
The system draws a vacuum on a vessel and feed piping, at the destination. A plug of product will be drawn from the source when the source discharge valve is open. The method is used for manual or bag unloading stations.
Major pneumatic system components include:
1. Positive Displacement Blower or Air Compressor with High pressure and Low flow characteristics
2. Pressure pot Systems, including venting chamber
3. Pipework including bends, straights, flexible couplings, elbows;
4. Cyclones, and unloading hoppers
5. Dust collectors and bin vents
6. Controls Systems
7. Gain-in-weight and loss of- weight batching systems
8. Associated Silos, day bins, weigh hoppers, bulka bags systems, etc
Key Points of Dense Phase Conveying:
Use dense phase pneumatic systems for minimum particle attrition and lowest pipe wear. The key design points are:
1. Allows higher density products to be conveyed
2. High system pressures (15 -- 90 psig)
3. Low air to solids loading ratios (less than 0.2)
4. Low velocities but high Kg capacity
5. Less erosion -- a result of lower velocity
6. Higher capital costs at startup
7. Pressure rated lines, valves, etc.
