Highly-efficient systems from Germany’s ScrapeTec 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.

 

HS Industrial Technologies works closely with Germany-based ScrapeTec to offer diverse industries in  India 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.

 

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 shortterm, 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.

 

The contact-free AirScrape conveyor belt skirting system is 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.

 

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.

 

These blades deflect larger particles inwards, while using the air-flow of the conveyor belt and conveyed material to create an inward suction, flowing any dust and fine particles back into the product flow. Through these diagonally fitted plates and the speed of the running belt, air is drawn from the outside inwards. As a result, neither the dust nor material can escape.

 

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, it is highly recommendable for 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.

 

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. These advanced conveyor belt systems – which meet stringent quality,  safety and environmental standards – are available directly from HS Industrial Technologies (India), which provides an assessment and solutions service to customers in diverse sectors, for planning and implementing projects.
