New machine combination for the production of EBV-compliant recycled building materials
Higher quality, higher yield: The machine combination reliably separates unwanted light and impure materials from mineral materials. This significantly increases the quality of the end product and boosts the yield for recycling companies. “The EBV specifies clear limits for foreign and impure materials. Conventional processes reach their physical limits here,” says Enrico Kallmeyer, Managing Director of MESDA Germany. “This is exactly where our solution comes in: The combination of MESDA and HAKO machines enables our customers to reliably produce high-quality recycled building materials and significantly increase the added value in their processing plants.”
The HAKO WS 1400 uses the float-sink process, also known as density separation. Unlike conventional wind sifting, this process uses water as the separating medium. Due to the significantly greater differences in density in water, the machine effectively separates light materials such as plastic, polystyrene, and wood from heavy materials such as stone and concrete. The result is a contaminant-free end product that meets the strict criteria of the EBV.
Flexible and self-sufficient in use
Lars Fürhölter, Managing Director of HAKO BAU GmbH, emphasizes that the decisive advantage of the combination lies in its flexibility: “The machines can be operated independently on construction sites, as the MESDA S8H screening machine supplies the HAKO WS 1400 with power. Thanks to the perfectly coordinated material transfers, they work together smoothly.” Integrating the lightweight material separator into existing recycling plants is also simple and straightforward. Thanks to its compact transport dimensions and hydraulically swivelling discharge belt, the HAKO WS 1400 can be easily moved by hook lift. This makes it the ideal solution for changing locations. It also impresses with low operating and disposal costs and low maintenance requirements.
The energy-efficient S8H coarse screening plant operates with an advanced diesel-electric hybrid drive. It can be flexibly connected to the on-board 129 kW diesel engine (EU Stage V) or optionally to an external power source for emission-free and cost-effective operation. In addition, the generously sized, purely electrically powered double-deck screen box (5.0 m x 1.5 m) increases the energy efficiency of the plant. This enables the machine to achieve a throughput of up to 500 t/h and ensures maximum productivity during demanding primary screening.
