Product Introduction
The DJFB series is designed for "Containment First." By fully encapsulating the conveyor belt within a rectangular steel shell, it prevents dust and odors from escaping. This is critical for urban waste-to-energy plants or facilities handling light, fluffy materials like RDF or biomass that would otherwise blow away.
Why Choose the "Enclosed" (DJFB) Model?
Standard sidewall conveyors are open to the air. While they save space, they can create a mess if you are handling dusty materials like dry coal, cement clinker, or lime powder.
The DJFB Model features a sealed steel casing (cover) along the entire conveying route.
- Zero Pollution: Keeps hazardous or messy dust inside the machine, protecting your workers and meeting EPA standards.
- Weather Protection: Protects your material from rain, wind, and moisture if installed outdoors.
- Safety: Prevents moving parts (cleats and rollers) from being exposed, reducing accident risks.
Typical Applications
- Thermal Power Plants: Lifting coal dust to the boiler bunker without polluting the facility.
- Grain Silos: Vertical transport of wheat or corn. The enclosed design prevents pest entry and grain loss.
- Chemical Plants: Handling toxic or corrosive powders that must not leak.
- Steel Mills: Transporting metallurgical flux or slag.
Structure & Design
- The Casing: Made of rigid Carbon Steel or Stainless Steel panels. It includes observation windows and maintenance doors so you can still check the belt without removing the cover.
- The Belt: Uses a Cross-Rigid Base Belt with corrugated sidewalls and diaphragms (cleats). This "pocket" design holds material securely during vertical lift.
- Dust Collection Ports: We can pre-install flange ports on the casing to connect to your central Dust Collector system.
Technical Specifications (DJ Series)

| DJFB-1200 | 1200 | 300 | 230 - 350 | < 150 |
Regional Adaptability - Belt & Road
- Urban Infrastructure: Ideal for projects in Thailand or Vietnam with strict dust and noise regulations.
- Tropical Rain Protection: The enclosed shell keeps dry fuels (like biomass) dry during monsoon seasons.
FAQ
Q: How do you clean the fines inside the box?
A: The DJFB features a clean-out drawer or secondary scraper at the base for easy recycling of fines.
Q: Is it suitable for toxic waste?
A: Yes, the fully enclosed structure prevents toxic dust exposure to workers.
Q: Is it hard to maintain the belt inside the box?
A: No. We place maintenance doors at every critical point (pulley, idler sets). You don't need to dismantle the casing for daily checks.
Q: Can it handle hot materials?
A: Yes. By using EPDM heat-resistant rubber belts, it can handle materials up to 150°C-180°C inside the enclosed casing.
Several customers have adopted the DJFB system to replace traditional open conveyors, achieving cleaner production environments, reduced material waste, and improved operational stability.
