Challenge
The batching plant needed accurate dosing of each material and the same mix quality batch after batch, with an operator view of the whole plant.
Solution
Each material is now dosed to its target weight: cement, aggregates, water and additives. The PLC runs the batching and mixing sequences automatically. The control system is built on a Siemens S7-1200 PLC with WinCC Professional SCADA.
Operators select and manage mix recipes and follow the plant on a SCADA overview of bins, hoppers, conveyors and mixer, with live values, timers and alarms.
Scope of work
- Siemens S7-1200 PLC programming
- WinCC Professional SCADA screens
- Dosing of cement, aggregates, water and additives
- Automatic batching and mixing sequences
- Recipe management for concrete mixes
- Real-time monitoring and alarms
Result
Each mix is dosed by weight from its stored recipe, and batching and mixing run automatically. The operator follows the whole plant on one SCADA screen, with live values, timers and alarms.
