Denseveyor System
Compared to other dense-phase pneumatic conveying systems, Denseveyor is cost-effective and provides an excellent combination of durability, reliability and performance. Its simple design has just one moving part – the patented Dome Valve. This makes it a fully enclosed conveying system that offers a dust-free process and is environment-friendly. What’s more, it is also energy-efficient, reduces pipe wear, and maintenance downtime.
As a leading manufacturer of Denseveyor – advanced dense-phase pneumatic conveying system, we can provide fully customizable systems depending on the material characteristics and conveying distances. Our products can be easily adapted to work alongside existing process layouts and equipment footprints.

How Denseveyor Works
Understanding Phase Density
The Denseveyor’s performance is built around a single engineering principle: air efficiency & optimal aeration. In practical terms, this means more material is pushed through the pipeline using significantly less compressed air than conventional dilute-phase systems, translating directly into lower energy costs and reduced compressor sizing requirements.
Denseveyor Operation
The Denseveyor works on either automated level mode or on timer mode basis. The Denseveyor cycle is batch wise in nature i.e. it transfers one batch of material at a time.
The Denseveyor first gets filled with material, it is then pressurized to an optimal range and then the powder is conveyed in fluidized manner to the destination. Once the material reaches the destination, a new batch is taken for conveying.
This closed-loop, self-regulating cycle is what allows the Denseveyor to run automatically with minimal operator intervention.

Why Choose Denseveyor?
The Denseveyor stands out among dense phase conveying systems due to its cost-effectiveness, reliability, and robust performance. Its simple yet innovative design incorporates only one moving part, the patented Dome Valve, ensuring high operational reliability and minimal maintenance.
Key Advantages:
- Gentle Conveying: Low velocity minimises product degradation and segregation
- Handles Tough Materials: Suitable for hot, abrasive materials
- Energy Efficient: Optimised air usage reduces operational costs
- Low Maintenance: Minimal moving parts ensure reduced downtime
- Dust-Free Operation: The fully enclosed system promotes a cleaner, safer environment
- Durable Design: Reduced pipeline wear extends system life
Available Configurations
Denseveyor systems can be engineered around your specific plant layout using several proven configurations:
- Multi-Feed to Single Reception: Multiple source points converge into one central reception vessel
- Single-Feed to Multi-Reception: One source feeds multiple destination points
- Single-Feed to Single Reception: Straightforward point-to-point transfer
- Multi-Feed to Multi-Reception: Complex plant layouts with several sources and destinations
- Long-Distance Multi-Stage Conveying: Booster-assisted staging for extended conveying distances
This flexibility means an existing Denseveyor design can typically be adapted to new or expanding plant footprints without redesigning the core system.
Engineering, Testing & Turnkey Support
Every Denseveyor system is backed by dedicated research, testing, and engineering capability:
- Materials Characterisation & Testing: Bulk material samples are analysed in a dedicated testing facility before system design begins, connected to full-size pipelines for real-world performance verification. This ensures the system is guaranteed to meet your specific material and throughput requirements before it's built.
- Turnkey Engineering Services: Beyond the conveying equipment itself, Macawber can support the complete project scope, including structures, storage systems, pressure vessels, control and instrumentation systems, and mechanical/electrical installation and startup.
- Custom Fabrication for Food-Grade Applications: Denseveyor systems are available in custom-fabricated 304 and 316 stainless steel for sterile transfer of ingredients and finished products in food processing environments.

Frequently Asked Questions
Dense conveyor systems are built to handle difficult-to-convey dry bulk materials, including powders, granules, pellets, and irregularly shaped solids, across a wide range of conditions, including hot, wet, and abrasive materials. Common applications include foundry sands (resin-coated, green, and reclaimed), coal, coke, and fly ash; raw and roasted foods (peanuts, corn, sugar, and salts), chemicals and plastics (titanium dioxide, PVC/CPVC pellets, and pebble lime); and alternate fuels such as wastewater sludge and paper/pulp waste.
Yes. The Denseveyor’s low-velocity, non-fluidising conveying regime is specifically designed to protect friable products from degradation and prevent blended or coated materials from segregating during transfer, something high-velocity dilute-phase systems cannot guarantee.
Yes. Because internal pipe wear increases with the square of material velocity, the Denseveyor’s low-speed conveying dramatically reduces erosion even with abrasive media like sand, ash, and coke fines. The system’s dome valve and standard Denseveyor systems handle temperatures up to 300°C.
Dense conveyor systems are widely used across foundry, power generation (coal/coke/fly ash handling), food and beverage processing, chemicals and plastics, glass, cement, steel, and alternate fuel/waste treatment industries: anywhere difficult, abrasive, hot, or friable materials need to be conveyed reliably.
Denseveyor systems achieve high phase density (30–150), meaning more material is moved per unit of compressed air than conventional systems, which directly lowers energy costs. With just one moving part (the Dome Valve), rated for up to 500,000 cycles between inspections, maintenance requirements and downtime are kept to a minimum, further reducing total cost of ownership.
Yes. Denseveyor systems can be custom-fabricated in 304 and 316 stainless steel for sterile transfer of ingredients and finished products in food processing facilities, meeting the hygiene and material-contact requirements of the food industry.
Very little. The system’s only moving part, the patented Dome Valve, is rated for up to 500,000 cycles between scheduled inspections, even in abrasive-material applications. The design also eliminates the need for level probes or outlet valves inside the vessel, further simplifying maintenance and reducing potential failure points.
Yes. Dense conveyor systems are engineered around your specific material characteristics, throughput, and conveying distance and can be configured as multi-feed-to-single-reception, single-feed-to-multi-reception, batch weigh systems, or long-distance multi-stage systems. Dome valves are available in sizes from 4″ to 20″ with pressure ratings from full vacuum to 600 psig, allowing systems to be adapted to virtually any existing plant footprint.
