The DustScrape is a combination of dust filter cloth and AirScrape and is highly effective against dust formation.
The filter cloth is stretched across the conveyor belt keeping dust particles that accumulate due to the material movement within the conveyor flow. At the same time the filter cloth is permeable to air. The fabric is especially designed for dust particles and has self-cleaning property allowing long-lasting dust retention. The filter cloth is effective against deflation of dust or smaller material particles and can be delivered in different qualities depending on the environment e.g. filter cloth with anti-static properties. There are dust curtains in regular distances supplementing the effect of the dust protection system and additionally prevent dust formation.
The DustScrape is a combination of dust filter cloth and AirScrape and is a highly effective system against dust formation. An efficient compact solution for dust-free belt conveyors with comparatively low costs and energy input.
A DustScrape-unit has a system length of 2 m and is available for all belt width. That is why belt sections of optional length can be equipped or upgraded with the DustScrape. The selection of the appropriate AirScrape® is dependent on the loading width of the conveyor belt and the required load-free area at the side of the belt. In the load-free are the side sealing works by means of air suction and the accompanying dust retention properties. The filter cloth stretch over the material is permeable to air and excess air can escape.
The AirScrape side sealing and the filter cloth in combination form the DustScrape system. The AirScrape does not allow dust or fine material to exit. Additionally, the arrangement of the lamellae has the effect that coarse material is led back to the middle of the belt and thus avoiding material spill completely. The contact-free concept protects the side sealing and the belt and maintenance intervals have become redundant. Because of the filter cloth properties, the material and dust are kept in the plenum and excess air can escape through the pores. Accumulating pressure is thus being released. Active dust removal or enlarging of the closed plenum that is usually connected to costly modifications is redundant.
