Effective dust control in mining means substantial cost savings

Scrapetec specialists work continuously on solutions for addressing specific challenges at conveyor system transfer points in industries where dust and material spillage are significant concerns. This encompasses sectors such as mining and quarrying.
The risk of explosions caused by dust emissions on conveyor belts is an ongoing problem that engineers around the world are trying to prevent. ScrapeTec experts developed a new dust control system about five years ago, that is proving to be highly effective – not only for preventing dust formation and material spill, but also to minimise the risk of explosion at critical sections along the conveyor route and transfer points and for more efficient belt-cleaning.

ScrapeTec products – which are engineered in Germany to pristine quality and environmental standards – are proving to offer even greater operational cost savings in materials handling, than anticipated at the launch of the range.

Apart from the benefit of cost savings, DustScrape and AirScrape dust suppression systems are highly effective in minimising exposure of workers to environmental pollution, which is a major problem caused by fugitive dust in dry bulk handling.

Although conventional dust prevention side-seals do reduce conveyor problems in the short-term, these components quickly deteriorate as a result of friction and can also damage the belt of the conveyor during extended periods of use.

Safety measures

The success of the combination of the DustScrape and AirScrape contact-free AirScrape conveyor belt skirting system systems, is in effective energy-free dust suppression. This compact and easy to install skirting adheres with most new dust prevention guides, to prevent health and safety issues on-site. This advanced system also minimises product loss, by effectively preventing material from escaping into the surrounding environment. As a result, users benefit from substantial savings of energy, housekeeping and maintenance costs, without the need for collection of material spills.

In a recent installation, they have solved many production problems for their customer, who was losing almost 5% of materials on conveyor belts, as a result of dust and material spill.” DustScrape 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 cleaning and dust-releasing properties, is available with different qualities, including anti-static features, for specific applications – for example, in surface or underground mining. The dust retaining filter cloth, which is manufactured in rolls, can be extended to any required length and is suitable for any conveyor belt width.

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.

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 blade 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.

Conventional skirting is pressed against a conveyor belt to keep dust and material in the middle of the belt, but after a period, wear of the skirting and belt can be so severe, that material and dust escapes. Material spillage at transfer points needs to be removed and regular maintenance of belt skirting and transfer points is necessary.

Studies show that even five years after installation and with continuous use in harsh conditions, the AirScrape system shows hardly any signs of wear. This durable system consists of non-flammable and anti-static polyurethane materials and blades made from Stainless Steel. FDA-approved materials are also available for specific conveyor handling applications.

Problem solving in cement production: dust and spills
ScrapeTec work closely with customers in various industries to address dust emissions,material spillage, conveyor belt damage, preventing production downtime, expensive repairs, and hazardous accidents, as seen in a recent project where a cement industry. In a recent project, a cement production plant needed assistance with excessive dust emissions during the handling of clinker, sand and gravel, that were causing Occupational Health and Safety (OHS) issues. In addition, the operator faced the problems of costly material spillage and the need for ongoing conveyor belt repairs. A comprehensive site inspection revealed that a standard chute sealing system was used in conjunction with a basic clamping system positioned outside the chute. The existing skirting system and lack of inner skirting failed to contain excessive dust emission and material spillage at the transfer points. High dust levels resulted in poor visibility of the 70-metre-long conveyor tunnel, which negatively affected the maintenance team’s ability to monitor efficiencies during the ship unloading process and to prevent bottlenecks in the production process. “Apart from concerns about safety and environmental hazards, management needed to find
