Dust Solutions for Bulk Handling Conveyor Systems

Powder Bulk Solids Staff | Sep 10, 2020

Scrapetec offers advanced solutions for conveyor systems used in diverse industries for 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 Thorsten Koth, sales and distribution for Scrapetec. "These highly-efficient systems prevent dust formation, reduce material spill, enable thorough belt-cleaning, and minimize 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 minimizing 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."

The contact-free Airscrape conveyor belt skirting system is an 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 are eliminated and service life of every component of the conveyor is extended.

The Airscrape system encompasses inward facing, hardened-steel diagonal blades and operates according to a new principle where it hovers 1-2 mm, on the left and right side above the conveyor belt.

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.

Tailscrape is mounted precisely to the existing Airscrape system, so that it seals the transfer to the bend, averting dust generation and material spillage, also reducing the risk of explosion.

For production areas with excessive dust generation, Scraptec specialists recommend 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 durable filter cloth--which retains dust particles created by conveyed materials while remaining permeable to circulating air--is available with different qualities--including anti-static features--for specific applications (i.e. underground mining).

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.

The maintenance-free tensioner system adjusts the blade pressure to the conveying condition, ensuring blades are pressed onto the belt, with optimum pressure at all times during operation. Low stress on the belt reduces damage and wear. The flexible scraping assembly is able to swivel into a lower position for reversible operation. Durable scraping blades are manufactured from a high alloy and are designed to re-sharpen automatically, by scraping against the belt.
