Optimize Material Handling with Custom Pneumatic Conveying Systems
Many facilities struggle with frequent blockages, excessive dust emissions, and inconsistent feed rates that slash production uptime. Custom pneumatic conveying systems solve these challenges through precision engineering and intelligent automation.
Pneumatic conveying uses air pressure to transport bulk materials through enclosed pipelines. These systems deliver clean, efficient, and safe material handling—especially for powders, granules, and bulk materials. Unlike off-the-shelf solutions, custom-built pneumatic conveyors are engineered specifically for your operational requirements, plant layout, and material characteristics.
Understanding Pneumatic Conveyors
Understanding the versatility of these systems and their applications across different industries is essential for selecting the right type of pneumatic conveyor—this ensures the system not only fits the facility’s physical layout but also enhances operational efficiency and safety, meeting the specific needs of various industrial processes.
Dilute vs. Dense Phase Pneumatic Conveying
Dilute Phase Conveying
Materials are suspended in high-velocity airstreams at low concentrations (<15kg material per kg air). This method works best for non-abrasive, lightweight materials like flour and plastic pellets.
Dense Phase Conveying
Materials move at low velocity in slugs or plugs at higher concentrations (>30kg material per kg air). Ideal for abrasive, fragile, or heavy materials such as cereals and powdered carbon black.
Pressure vs. Vacuum Pneumatic Conveying Systems
Pressure
Air movers push materials from a single pickup point to one or multiple destinations using positive pressure. Best for long-distance conveying (up to 300+ meters), high-capacity operations, and applications requiring multiple discharge points.
Vacuum
Vacuum pumps pull materials from one or multiple pickup points to a single destination using negative pressure. Ideal for dust containment, multiple source collection, and applications requiring zero material leakage since any system leaks draw air in rather than releasing material.
Industry-Specific Applications
Pneumatic conveyors are not just limited to granular or powdered materials; they also play a crucial role in industries handling other forms of bulk materials.
Granular and Powdered Materials
Plastics Manufacturing
Chemical Processing
Pharmaceuticals
Cement and Mining
Handle abrasive materials like cement, fly ash, and mineral powders in high-volume operations.
Bulk Materials Beyond Powders
Paper and Textiles
Pneumatic systems remove trim waste and fibers from production areas to collection sites, reducing manual handling.
Laundry Facilities
Industrial pneumatic conveying systems transport soiled linens from the receiving area to washers and clean items to sorting areas, improving hygiene while reducing labour costs.
Common Challenges Solved by Pneumatic Conveying Systems
Manufacturing facilities frequently encounter material handling problems that impact productivity and safety:
- Frequent blockages in standard systems cause costly downtime and require manual intervention
- Dust emissions create health hazards, contaminate products, and violate environmental regulations
- Material degradation from improper conveying damages product quality and increases waste
- Inconsistent feed rates disrupt downstream processes and reduce overall equipment effectiveness
- High energy costs from inefficient air movers and poorly designed pipeline routing
- Safety risks from handling hazardous or combustible materials in open systems
Custom pneumatic conveying design addresses these specific pain points by engineering solutions around your exact materials, facility constraints, and operational goals.
Why Custom Pneumatic Conveying Systems Outperform Standard Solutions
