The collection of dust emisions from brushing processes can be accomplished in different ways. Either dry or wet separation processes are suitable. Distinctions between exhaust air operation or recirculating air operation are decisive in choosing the correct technology.
For dry separation are applied units of the VARIO and PT series. 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.
