Reliable Collection, Extraction and Separation of Very Fine Dust Caused by Surface Treatment Methods
Brushing of metal and non-ferrous metal (e. g. aluminum) produces emissions of fine particulate which even the most advanced production technology cannot prevent. Collecting and removing these fine dusts using suction is mandatory.
Brushing or coating processes can form deposits. The resulting dusts are often explosive and combustible, which must be considered in the system design. Also, the dimensions of the dust collection/extraction area must be taken into account, which is usually done by the machine manufacturer.
Suitable Dust Extraction Technologies with Explosion Protection and Clean Air Recirculation
The collection of dust emissions from brushing processes can be accomplished in different ways. Either dust collection or wet separation processes are suitable. Distinctions between exhaust air operation or recirculating air operation are decisive in choosing the correct technology.
For dust collection, units of the VARIO and PT series are applied. The filters are chosen depending on the requirement.
To protect the filters, limestone powder is added via a dosing unit (in the event of oily air in the plant), which creates inertisation. This is relevant, especially with explosive or combustible dusts, since a corresponding explosion and fire protection strategy is required. An additional consideration is whether the unit will be located indoors or outdoors.
