The Positive Pressure Dense Phase Pneumatic Conveying System is a highly efficient bulk material transfer solution designed for powders, granules, and difficult-to-handle materials.
By using compressed air at 0.15–0.3 MPa, the system conveys materials at a low velocity of 3–8 m/s while maintaining high material-to-air ratios (20–100, or even up to 300–400). This ensures reduced material degradation, minimized pipeline wear, and improved conveying efficiency.
This dense phase pneumatic conveying technology is widely applied in power plants, chemical industries, building materials, food, metallurgy, plastics, and pharmaceuticals, especially for abrasive, fragile, or cohesive materials.
Advantages
Reduced Wear & Tear: Low air velocity minimizes pipe and material abrasion, making it ideal for fragile or abrasive materials.
Low Energy Consumption: Requires only small-sized compressors due to low air volume demand.
High Material Loading: Ensures high material concentration with efficient delivery.
Compact Design: Small footprint and space-saving structure.
Less Material Sticking: Prevents buildup and sticking inside pipelines.
Environmentally Friendly: Dust-free, sealed conveying reduces pollution.
Flexible Operation: Easy to automate and adapt for continuous or batch feeding.
Applications
Power Industry: Fly ash, coal powder, desulfurization additives.
Building Materials: Cement, lime powder, gypsum, alumina.
Chemical Industry: PVC resin, soda ash, carbon black, catalysts.
Food Industry: Flour, starch, sugar, and other fine powders.
Metallurgy: Metal powder, blast furnace additives.
FAQ
Q1: What is the working pressure of the dense phase conveying system?
A1: The system typically operates at 0.15–0.3 MPa with stable conveying pressure.
Q2: What types of materials can it handle?
A2: It is suitable for powders, granules, abrasive, fragile, and cohesive materials such as cement, fly ash, PVC resin, flour, and metal powders.
Q3: How does it prevent pipeline wear?
A3: Dense phase conveying uses low-speed airflow (3–8 m/s), which reduces pipe friction and material degradation.
Q4: Is it energy-efficient compared to dilute phase conveying?
A4: Yes, it requires a smaller air compressor and lower air volume, reducing overall energy consumption.
Q5: Can it be integrated into automated production lines?
A5: Absolutely. The system supports PLC automation, batch feeding, and continuous conveying.
