Project Description
At its Rothenburg facility, Belag und Beton AG produces asphalt mix, concrete, and mortar, as well as recycled, sand, and gravel materials.
Since the existing cement slurry dewatering system, installed in 2019, had reached its capacity limit, the plant was expanded to include a second chamber filter press of the same design. The new chamber filter press was seamlessly integrated into the existing plant design and can be operated independently of the existing filter press.
The resulting redundancy allows peak loads to be reliably managed and maintenance work to be planned more flexibly. At the same time, it reduces the workload on operating personnel during daily plant operations.
The scope of delivery includes a KFP-A 630-11/11-C35-8-S1 chamber filter press, a 20-foot module, a feed pump with a flow rate of up to 10 m³/h, and the complete electrical control system, including PLC control. Engineering, project management, installation, commissioning, and acceptance testing were also part of the contract.
