Pneumatic Material Conveying
Pneumatic conveying is the process of moving dry bulk solids (like cement, fly ash, plastics, sand, flour, sugar) through pipelines using pressurized air or vacuum. Roots blowers serve as the prime movers by creating high-velocity air streams that entrain and transport the solids.
Critical Engineering Requirements
- High pressure rating: Overcoming pipeline friction requires blowers that maintain flow rate under varying pressures.
- Robust casing seals: Ensuring no product enters the blower casing and no timing oil leaks into the conveying line.
- Vacuum options: Suitable for suction-based unloading from trucks, silos, or ships.
Engineering Selection Tip:
Water-cooled roots blowers are recommended for conveying heavy materials like cement over long distances, where continuous high back-pressures generate extreme compression heat.
