Explosive Dust Extraction – Safe and Certified Solution

When processing certain materials – especially during grinding and polishing – explosive dust can be generated. Extracting such dust must comply with strict safety standards and technological requirements. Our solution is designed with a strong emphasis on protecting personnel, equipment, and the building itself.

Technical Solution for Explosive Dust Extraction

Source Extraction Efficiency
Dust is captured directly at the point of release during grinding or surface treatment using extraction hoods placed at the source.
 

Explosion-Resistant Ducting
The extraction ductwork is made of thick-walled welded sections with high pressure resistance and is equipped with a backdraft damper to prevent pressure wave propagation in case of an explosion.
 

Jet BAG Filtration Unit
We use the proven Jet BAG filter system featuring:
 

• Antistatic filter media designed for explosive dust applications

• Automatic regeneration using compressed air for continuous and stable operation
   

Explosion Relief System
Explosion relief membranes are directed to a safe outdoor area above the filter to prevent damage to surrounding equipment and ensure operator safety.
 

Certified Rotary Valve
A certified rotary valve installed under the filter isolates explosive zones and ensures safe discharge of collected dust into containers.

Reducing Dust Explosivity Using Sorbent

An integrated dosing station adds sorbent into the duct system at regular intervals. This additive:

• Improves the regeneration of the filter media

• Reduces the explosivity of the dust mixture

• Enhances the overall safety of the extraction system

Key Advantages of the System

• Certified ATEX-compliant technology

• Extraction with high focus on safety

• Antistatic and robust filter media

• Explosion risk minimized through sorbent dosing

• Adjustable extraction performance via frequency inverter
