Introduction
Automation drives consistent product quality and efficiency. Hengshui Decheng Machinery & Equipment Co., Ltd’s automatic gypsum powder production lines integrate advanced control systems, robotics, and diagnostics to minimize manual intervention.
Integrated Control Architecture
At the core is a PLC network linking all major subsystems—crushing, milling, calcining, cooling, and packing. A central SCADA server gathers live data, displaying dashboards for feed rates, mill power draw, kiln temperature profiles, and silo levels. Operators can initiate recipes that adjust each stage automatically.
Automated Material Handling
Bulk gypsum is unloaded via pneumatic unloaders into hopper feeders equipped with load cells. Conveyors with photoelectric sensors maintain line speed by adjusting belt drive frequency. Pneumatic diverter valves route powders to multiple silos or packaging lines based on pre‑set formulas.
Online Quality Monitoring
Inline particle size analyzers and moisture sensors feed real‑time readings back to the PLC. If powder falls outside defined parameters (e.g., 25–45 µm or 0.5–1.0% moisture), the system alerts operators or automatically adjusts classifier speed and residence time in the dryer.
Robotic Packaging
Finished powder is automatically weighed, bagged, and palletized. Robotic arms handle bags, ensuring consistent fill levels. Vision systems read and verify batch codes printed on each bag, feeding data back to the ERP for inventory tracking.
Predictive Maintenance
Vibration sensors on bearings, thermal cameras on hot zones, and current monitors on motors allow the control system to predict component wear. Scheduled maintenance is then automatically generated, reducing unplanned downtime.
Conclusion
An automatic line from Hengshui Decheng combines material handling, process control, quality assurance, and packaging robotics into a coherent whole—delivering high throughput with minimal labor requirements.
