Automation solutions in the building materials industry
Mixing and batching operations within the building materials industry present a special challenge for process control engineers. Diverse components and processes are integrated into a comprehensive automation concept which is enables maximum uptime, higher productivity and significantly reduced cost of ownership. KELLER IAS is highly skilled and experienced in this field.
Upgrading and retrofitting an asphalt mixing plant
A retrofit with state-of-the-art automation technology can be a viable alternative to replacing it with an all-new automation system, as evidenced by KWS, an asphalt mixing plant in the Netherlands, located in the town of Staphorst near Meppel. The equipment at this plant was controlled by Simatic S5 PLC. Prior to modernisation, the facility was controlled by Simatic S5 and visualisation and recipe control were based on MS-DOS. Both the software and the hardware needed an overhaul because S5 components had become difficult to source. With minimal downtime, KELLER implemented an open-system, modular architecture for controls, including a sophisticated visualisation tool.
Concrete mixing plant
The Lücking Company in Bomberg, Germany uses KELLER automation to control their dosing and metering processes. A belt weigher and batch weigher, both connected to strain gauge load cells, transport bulk solids such as sand, gravel or cement to the mixer.
Clay mixers for ceramic industry
The KPCL Company in Tirschenreuth, Germany uses KELLER IAS software to control their mixing and dosing processes of ceramic materials and other raw materials for the manufacture of fine ceramic products.
