The QMH Airflow Dust Suppression System is engineered to capture and control dust at the source during material transfer. By combining airflow control and sealing structures, the system keeps dust within the enclosure and allows particles to return to the material stream.
Design Concept
The system creates a controlled airflow environment at transfer points, ensuring that air flows inward rather than outward. Dust particles are captured through filtration and guided back into the conveying process.
DustScrape (Primary Dust Capture)
Installed at key transfer points, DustScrape uses filter cloth to capture fine dust while allowing airflow to pass through. It is available in multiple sizes and can be retrofitted to existing conveyor systems.
AirScrape (Airflow Sealing System)
A non-contact side sealing solution that uses airflow generated by belt movement to create a suction effect. It helps keep dust within the material zone while reducing belt wear.
TailScrape (Secondary Recovery)
Installed at the tail section, it redirects spillage and fine particles back onto the belt, minimizing material loss and dust escape.
Containment Seal
Designed with low-friction materials, this component controls internal pressure and prevents dust leakage under heavy material flow conditions.
The Airflow Dust Suppression System utilizes airflow generated by the moving conveyor belt. Guided by structural components, air is drawn into the transfer zone, creating a slight negative pressure environment. Dust particles are retained inside and settle back into the material stream through filtration and airflow control.

Source-Level Dust Control
The QMH Airflow Dust Suppression System controls dust where it is generated, reducing dispersion at transfer points.
Reduced Dependence on Dust Collectors
It can lower the load on traditional dust collection systems, helping reduce energy consumption and maintenance requirements.
Non-contact Design
AirScrape does not contact the belt surface, minimizing wear and extending the service life of conveyor components.
Compact Installation
The system requires minimal additional space and can be integrated into existing conveyor layouts.
Lower Operating Cost
Reduced airflow demand and less frequent maintenance contribute to overall cost efficiency.

In a coal transfer station upgrade project, the installation of the QMH Airflow Dust Suppression System helped reduce visible dust emissions at transfer points and decreased the operational load on existing dust collection equipment.
FAQ
Q1: Can this system be installed on existing conveyors?
Yes, the system supports retrofit installation and can be adapted to most conveyor configurations.
Q2: Is a bag dust collector required?
Not always. Depending on dust levels, the system can operate independently or alongside existing collectors.
Q3: How often does it require maintenance?
The system is designed for low maintenance, with periodic inspection recommended.
Q4: Does it affect conveyor performance?
No, the non-contact design ensures no additional resistance or belt wear.Company & Service SupportQMH_Qingdao Quality Material Handling Co., Ltd. has over 30 years of experience in bulk material handling technology, offering integrated services including system design, diagnostics, and technical training.
