Granular Material Automatic Batching Production Line

**Operational Workflow of the Automated Dosing System**

Our Automated Dosing System workflow is engineered to ensure precise weighing, seamless material addition, and controlled discharge, all while monitoring system performance in real time. Here’s a breakdown of each stage:

1. **Weigh Hopper Calibration**: Each weigh hopper is equipped with load sensors connected to the industrial computer (PLC). Before initiating the dosing process, operators perform a manual zero-check to ensure accurate hopper calibration. During continuous dosing, the system automatically checks and adjusts the zero position of the weigh hopper, compensating for any drift to maintain high measurement accuracy.
2. **Material Dosing Process**:

– Upon initiation, the operator activates the dosing sequence via the control interface. The PLC then opens the pneumatic valve and screw feeder for Material A, allowing it to gradually enter the weigh hopper.

– The computer continuously monitors the load sensor data, comparing it with the target formula weight. Once the target weight for Material A is reached, the PLC halts the feeder and pneumatic valve, allowing the system to stabilize briefly.

– After stabilization, the weight in the hopper (now containing Material A) is recorded as the zero point for the next material addition.

– The process is then repeated for subsequent materials (Material B, Material C, etc.), sequentially adding each until all required materials are in the weigh hopper.

3. **Discharge Process**:

– Once all materials are dosed and meet the preset conditions, the discharge sequence begins. The pneumatic discharge valve opens, and the mixed materials flow out of the hopper by gravity.

– The system monitors the load sensor to track the hopper’s weight, ensuring it returns to the initial zero point, confirming the completion of the discharge. At this point, the discharge valve closes, and the materials proceed to the mixing phase.

4. **Data Logging and Control Options**:

– Operators can predefine the dosing sequence, managing the order and timing of each material addition.

– The system records critical operational data, including tank identification numbers, actual dosing amounts for each material, deviation from target values, start and stop times for dosing, and start and stop times for discharge.

– Through the upper-level computer application, operators can view and print raw data, operational logs, and statistical reports to facilitate quality control and production traceability.

This Automated Dosing System streamlines production with precise, real-time control over material addition and discharge, supporting efficient, accurate, and documented material handling for complex industrial processes.
