Reliable Collection, Extraction and Separation of Very Fine Dust Caused by Surface Treatment Methods
Brushing of metals and non-ferrous materials such as aluminum generates fine particulate emissions that even the most advanced manufacturing technologies cannot fully eliminate. Effective suction-based extraction is essential for safely capturing and removing these dusts.
Brushing and coating operations can also lead to the buildup of material deposits. The dusts created in these processes are often combustible or explosive, making it critical to address these risks in the system design. Additionally, the size and layout of the dust collection or extraction zone must be carefully considered, which is typically specified by the machine manufacturer.
Suitable Dust Extraction Technologies with Explosion Protection and Clean Air Recirculation
Dust emissions from brushing processes can be captured using either dry dust collection or wet separation methods. The choice between these technologies depends largely on whether the system operates with exhaust air or recirculating air.
For dry dust collection, systems from the VARIO and PT series are typically used. Filter selection is based on the specific application requirements.
When processing oily air, limestone powder is introduced through a dosing unit to protect the filters by creating an inert atmosphere. This is especially important when dealing with combustible or explosive dusts, as it forms part of a broader fire and explosion protection strategy. It’s also critical to determine whether the system will be installed indoors or outdoors, as this affects design and safety considerations.
