Automatic Dosing System with High Accuracy for Powder Material Processing
The Automatic Dosing System is designed for accurate weighing, dosing, and automatic feeding of powder, granules, and additives in industrial production. The system automatically controls each material according to preset recipes, improving production efficiency while reducing manual operation and material waste.
The equipment adopts a modular structure that integrates storage silos, weighing hoppers, feeding units, screw conveyors, vacuum conveying systems, and an intelligent PLC control system. Operators can easily manage multiple formulas through the touch screen, allowing fast product changes and stable production performance.
The weighing process is monitored continuously by high-precision load cells. Once the preset weight is reached, the feeding unit stops automatically, ensuring excellent dosing accuracy and repeatability. This automatic control minimizes human error while maintaining consistent product quality.
The system supports both batch and continuous production. After weighing, materials are automatically transferred to mixers, storage bins, extrusion lines, or other downstream equipment, creating a fully automated material preparation process.
Designed for flexibility, the Automatic Dosing System can be configured with different numbers of material stations, weighing capacities, and conveying methods according to customer requirements. It can also be integrated into existing production lines or supplied as part of a complete turnkey material handling solution.
The system is widely used in plastics, chemicals, food processing, building materials, masterbatch production, recycling, and many other industries where accurate material dosing is essential for maintaining stable production quality.
