In an aluminium processing plant, explosive aluminium fine dust accumulates on grinding tables and in a blasting cabin. Two low-pressure scrubbers with an air capacity of 6,300 m³/h each were installed for safe collection and separation.

The dust-air mixture is fed tangentially into the cylindrical wet dust collectors and set in motion by the round geometry. Heavy dust fractions are wetted and thrown against the container wall by centrifugal forces, then sink to the bottom. The radial fan placed on top of the unit creates the necessary negative pressure, which both overcomes the flow resistance of the unit and ensures extraction. At the same time, water is sucked into the venturi tube, creating an intensive washing zone. Even fine dust particles are reliably bound here.

The air, now free of dust and water, is then discharged into the open air. For continuous disposal of the separated sludge, an automatic discharge device with a scraper belt angle is integrated, which transports the sludge to the outside via a discharge chute.

Result: Highly effective dedusting of explosive aluminium dusts to improve occupational safety, minimise explosion risks and comply with environmental and occupational safety standards.
