In modern concrete batching plants, the efficient and reliable discharge of cement from storage silos is essential for maintaining consistent production quality and operational efficiency. WAMGROUP's Airless Cement Flow System has been developed to address these requirements, introducing an innovative approach that eliminates many of the limitations associated with conventional fluidisation systems.
At the heart of the system is DUPLOCON™, a patented discharge solution specifically engineered to ensure uniform cement flow from silos. Thanks to its unique internal geometry, DUPLOCON™ promotes homogeneous material discharge, helping to maintain consistent product quality while preventing flow irregularities that can adversely affect batching accuracy and plant performance.
One of the most significant advantages of DUPLOCON™ is its ability to operate without compressed air. Unlike traditional fluidisation systems, which require a continuous air supply and regular maintenance, DUPLOCON™ delivers reliable performance with minimal intervention. The elimination of compressed air consumption not only reduces operating costs but also simplifies plant management and improves overall system reliability.
Designed for long-term durability, DUPLOCON™ features a robust construction in carbon steel with a C3M protective coating compliant with ISO 12944 standards. Its seamless cone design optimises material flow, while the 900 mm diameter body and 323 mm (12-inch) outlet facilitate efficient and uninterrupted cement discharge.
The Airless Cement Flow System combines DUPLOCON™ with the latest-generation ES Screw Conveyor to achieve true mass-flow conditions throughout the discharge process. This integrated approach effectively prevents common silo flow problems such as bridging and rat-holing, ensuring a continuous and controlled feed of cement to the batching process.
By eliminating the need for fluidisation equipment and compressed-air infrastructure, the system delivers multiple operational benefits, including reduced energy consumption, lower noise emissions and simplified plant layouts. In many applications, the compact design also allows a reduction in overall plant height, providing additional flexibility during plant design and installation.
Beyond its technical advantages, the Airless Cement Flow System offers a compelling economic case. Reduced maintenance requirements, lower energy costs and decreased manpower involvement contribute to a significantly lower total cost of ownership. At the same time, the elimination of compressed-air consumption supports sustainability objectives by reducing energy demand and environmental impact.
With DUPLOCON™ and the Airless Cement Flow System, WAMGROUP has introduced a new benchmark for cement silo discharge technology. By combining reliability, efficiency and sustainability, the solution enables concrete producers to optimise plant performance, reduce operating costs and enhance product consistency in an increasingly competitive market.
