Innovative dust solutions for conveyor systems

BLT World works closely with ScrapeTec, to offer diverse industries in Africa advanced solutions for conveyor systems used in the handling of abrasive materials with excessive dust.
“AirScrape, DustScrape, TailScrape and SpeedScrape products, which encompass the latest technology, have been developed by ScrapeTec, to provide dependable solutions for specific problems – like dust, spills and contamination - at the transfer points of conveyor systems,” said Ken Mouritzen, Managing Director, BLT World, distributors for ScrapeTec in Africa, the Indian Ocean Islands and in the USA.
“These highly-efficient systems prevent dust formation, reduce material spill, enable thorough belt-cleaning and minimise the risk of explosion at critical sections along the conveyor route and at transfer points.
“Although conventional dust prevention side-seals do reduce conveyor problems in the short-term, they quickly wear-out as a result of friction and can also damage the belt of the conveyor during extended periods of use.
“Scrapetec’s robust systems, which are virtually maintenance-free, extend the service life of conveyor belts and reduce cleaning requirements of the entire conveyor system. Apart from cost-efficient operation, these products also contribute to occupational safety, environmental protection and safety, by minimising dust generation and contamination.
“Correct installation of this highly-efficient equipment ensures optimum performance, reduced risk of explosion, low maintenance and extended service life of the conveyor system.”
Mouritzen described the contact-free AirScrape conveyor belt skirting system as a highly effective side seal that lies over the conveyor belt, without contact, and creates negative pressure on the belt, due to its specially designed lamella structure. Because this system hovers freely above the conveyor belt, skirt friction and belt damage is eliminated and service life of every component of the conveyor is extended.
Mouritzen said studies had shown that even five years after installation and with continuous use in harsh conditions, the AirScrape system hardly shows any signs of wear. Operational costs are also reduced because there is no need for spillage collection, regular maintenance, or replacement parts.
The TailScrape system enhances performance of the AirScrape, by sealing the transfer tail in the rear area and also works according to the Venturi concept, to prevent dust generation and material spills. The intelligent blade structure on the underside of the system, creates negative pressure in the conveying area, preventing the escape of materials. Dust is kept in the material flow by air intake.
The TailScrape system is available in small, medium and large designs, suitable for all belt widths, to perfectly match the AirScrape variants. Because the TailScrape system also operates without contact to the conveyor belt, there is no belt or skirting wear. This system, which can be operated permanently with minimal maintenance requirements, also extends service life of conveyor components.
For production areas with excessive dust generation, BLT World recommends installation of the DustScrape. This 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.
The SpeedScrape secondary belt cleaner design is based on the inclined and staggered positioning of Tungsten blades, which increases the scraping surface to as much as 150% of the conveyor belt width. This high-performance system allows scraped material to be easily discharged.
