Automatic Additive Weighing and Batching System

The Automatic Additive Weighing and Batching System is designed for accurate, recipe-based weighing of minor ingredients used in PVC pipe, profile, and other PVC compounding applications. In a typical semi-automatic configuration, major raw materials such as PVC resin and calcium carbonate (CaCO³) are weighed separately, while the system automatically weighs powder and suitable granular additives according to preset recipes. Depending on the configuration, the system can handle 6–12 different ingredients, helping reduce manual weighing errors, improve batch consistency, and minimize material handling. **Main Features** - **Accurate Weighing:** Load cells and controlled feeding mechanisms help achieve consistent weighing results. Accuracy depends on the material characteristics and target batch weight. - **Automatic Feeding Speed Control:** The feeding speed can be adjusted according to the target weight, balancing dosing efficiency and weighing accuracy. - **PLC-Based Automation:** The system can be equipped with Siemens PLC control for automated weighing and batching operations. - **Modular Design:** Individual stainless steel ingredient hoppers and a centralized control cabinet provide a flexible layout for installation and maintenance. - **User-Friendly Operation:** A touchscreen interface allows operators to manage recipes, adjust operating parameters, and monitor weighing operations without modifying the PLC program. - **Customized Configuration:** The number of ingredient hoppers, weighing capacity, feeding mechanisms, and control functions can be configured according to customer recipes and production requirements. The system can be integrated with PVC mixing and material conveying equipment to support more consistent and efficient production.
