“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 six 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,” explains Thorsten Koth, Sales Manager at ScrapeTec.

ScrapeTec manufactures its products in Germany in accordance with the highest quality and environmental standards. Compared to conventional products in this segment, which reduce conveyor problems in the short term but wear out quickly due to friction, ScrapeTec products prove to be far more durable and efficient even with prolonged use, resulting in unusually high cost reductions. In addition, the DustScrape and AirScrape dust suppression systems are extremely effective in reducing dust exposure, making it safe to work in these areas and thus contributing to health and safety.

The success of the combination of the DustScrape and AirScrape contact-free AirScrape conveyor belt skirting system systems, is in effective energy-efficient 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.

“In a recent installation, we solved many production problems for our customer, who was losing almost 5 % of the material on the conveyor belts due to dust and spilled material,” says Thorsten Koth. The DustScrape system is specially designed to prevent dust emissions and consists of a filter box including a filter cloth. Adapter plates mounted on support arms hold the system above the belt. Inside, a rubber curtain prevents further dust formation. The system is individually tailored to the respective requirements and the material being conveyed. The DustScrape is a combination of DustBox + calming zone extension + AirScrape and is usually mounted behind the transfer box. The system is easy to install and can be retrofitted to existing conveyor belts. It is suitable for continuous operation and, due to its low maintenance requirements, also for long-term use.

The main features and functions of the DustScrape are:

Dust control: The DustScrape reduces dust emissions at transfer points for fine bulk materials to almost zero.

Pressure relief: In closed transfers, where high pressure can build up, the DustScrape provides effective pressure relief.

Filtering: The robust filter cloth allows air to pass through, while the filtered dust remains with the bulk material in the conveyor.

Energy efficiency: The system operates without energy consumption and does not require any piping.

Cost savings: DustScrape offers long-term cost advantages through reduced cleaning, maintenance and repair costs as well as improved health protection for employees.

Combining an existing active dust extraction system with DustScrape increases the effectiveness of the dust extraction system by at least 50 %. Energy is saved and the maintenance costs of the active dust extraction system are reduced.

The highlight of the ScrapeTec product range is the AirScrape. It is a highly effective side seal that is mounted above the conveyor belt without contact and exerts negative pressure on the belt thanks to its specially developed lamella structure. This physical property causes air to be sucked into the interior of the conveyor system, thus keeping any dust that is generated in the transfer area. The lack of belt contact eliminates the need for subsequent adjustments and also prevents belt damage, which has a particularly positive effect on the service life of the belt and the entire system.

Experience shows 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. For special applications in conveyor technology, such as use in the food industry, the AirScrape is also available with FDA-approved materials.

The ScrapeTec system also includes the PrimeTracker conveyor belt tracking assistant and the SureSupport belt support.

With PrimeTracker, ScrapeTec has added a track-holding assistant to its product portfolio that, like AirScrape, has unique features. Its maintenance-free bearing allows the rotating running body to change its axis position in all directions. It is the only product in this segment worldwide that is capable of performing a 360° rotation. The PrimeTracker therefore works differently from conventional belt guidance systems. It behaves like a conventional conveyor belt roller when the belt is running smoothly and only intervenes when the belt leaves its optimal position. The PrimeTracker corrects even the slightest off-centre belt guidance with small forces and very low friction, thus preventing unnecessary wear.

At transfer points, optimised material intake also helps to reduce dust and spillage. Belt support measures therefore contribute to functionality and ensure that the entire ScrapeTec system works optimally. SureSupport fulfils this task with flying colours. It supports and stabilises the belt in the feed area, which increases the effectiveness of the side sealing and prevents dust and material losses.

Used together, this product range forms the ScrapeTec system, which is unrivalled in terms of efficiency and cost-benefit analysis.
