At this steel plant, a Weba transfer chute is shown managing heavy material flow while effectively lowering dust emissions in a demanding environment.
Lining and sealing for dust containment A further feature of Weba’s design is the effective sealing of the chute system. Engineered with wear resistant liners and designed with attention to transfer geometry, the chutes prevent dust from escaping into surrounding areas. Where needed, dust suppression or extraction systems can be integrated seamlessly into the chute design, ensuring compliance with the most stringent emission standards. Weba Chute Systems’ in-house design team uses the latest simulation software, including discrete element modelling (DEM), to predict material behaviour inside the chute. This allows the company to optimise liners, flow paths and sealing systems before manufacturing begins. The result is a custom-engineered solution that not only contains dust but also minimises spillage and wear. “Our DEM capability gives us a powerful window into how the material will behave,” Tintinger points out. “We can predict dust issues before they occur and design them out of the system – that is a real gamechanger.” Efficiency and environmental gains Reducing dust transmission is not just about compliance; it also improves the bottom line. Dust that escapes into the air represents a loss of valuable product. By containing material more effectively, Weba Chute Systems help customers improve throughput and reduce waste. At the same time, less dust means reduced wear on conveyor components, lower cleaning and maintenance requirements and safer working environments. These gains contribute directly to operational efficiency and sustainability. “As much as dust control is a health and safety imperative, it is also a cost issue,” says Tintinger. “Every ton of material lost to dust is revenue gone. By addressing dust, we protect both people and profits.” Proven success across industries Weba Chute Systems’ dust-control solutions are in operation across a range of industries and commodities from mines to power stations, cement plants and other bulk handling facilities. Each system is custom engineered for its specific application, taking into account the type of material, the rate of flow, particle size and environmental requirements. In ports and loading terminals, where dust emissions are highly visible and subject to strict monitoring, the systems ensure compliance while maintaining fast loading rates. “Whether it is in large scale port operations or on a mine, the

principle is the same,” Tintinger says. “Control the flow, contain the dust and you achieve safer, cleaner, more efficient operations.” Commitment to innovation With decades of experience and thousands of installations globally, Weba Chute Systems continues to invest in innovation. Its dedicated research and development team works constantly to refine designs, enhance materials and explore new methods of dust suppression. The company’s approach is not limited to the initial installation. Weba Chute Systems provides ongoing inspection and maintenance services to ensure systems continue to perform optimally over their lifetime. Customers benefit from reliable transfer points that remain compliant and efficient long after commissioning. Tintinger says that as industries move towards more sustainable, responsible and efficient operations, dust control has become an imperative rather than an option. “Our engineered transfer points provide a holistic solution, reducing dust transmission, enhancing safety, safeguarding the environment and improving efficiency,” he says. “By addressing dust at its source - within the transfer point itself - we help operators move beyond reactive measures and achieve proactive control. This not only ensures regulatory compliance but also delivers lasting value to both business and society,” Tintinger concludes. n
