The DustScrape from BLTWORLD consists of a durable filtering cloth that is installed above the conveyor belt, to retain dust particles created by conveyed materials, while remaining permeable to circulating air.

This long-lasting filter cloth with self-cleaning and dust-releasing properties is available with different qualities, including anti-static features, for specific applications – for example, in underground mining.

“ScrapeTec’s German-engineered products have been specially developed for the prevention of dust formation and material spill and for more efficient belt-cleaning at critical sections along the conveyor route and transfer points,” says Ken Mouritzen, managing director at BLTWORLD. “AirScrape, DustScrape, SpeedScrape and TailScrape systems, which are easy to assemble and operate, form part of BLTWORLD’s custom-designed solutions service, to meet exact bulk material conveyor project requirements.”

The DustScrape dust emission prevention system comprises a filter cloth, support arches and skirts, arms to hold the system above the belt and a rubber curtain to eliminate further dust development – all sized to specific requirements. This system is easy to install and can be retrofitted to existing conveyors, for continuous operation and for extended periods.

“BLTWORLD’s DustScrape dust filter system, which is used in conjunction with the contact-free AirScrape conveyor belt skirting system, is a highly-effective, energy-free dust emission prevention system. This compact and lightweight system complies with most new dust prevention guides and prevents health and safety issues on-site. This system also minimises product loss, by effectively preventing material from being blown into the surrounding environment.”

The dust retaining filter cloth, which is manufactured in 2m long sections, can be extended to any required length and is suitable for any conveyor belt width.

Selection of the correct AirScrape size depends on the loading width of the conveyor belt and the required load-free zone of the belt edges. The AirScrape conveyor belt skirting system is installed above the load-free zone and generates the air-intake from outside, into the system. The generated airflow from above the conveyed material then gets filtrated through the filter cloth, retaining any dust particles, which are re-deposited back into the material flow.
