The automatic weighing system in a self loading mixer ensures precise batching of raw materials like cement, water, sand, and gravel by integrating sensors, control systems, and AI-driven interfaces. Positioned between the hopper and mixing cylinder, it monitors weights in real-time, adjusts proportions via computer algorithms, and maintains an error rate below 2%. This system combines hardware (sensors, hoppers) and software (touchscreen controls, AI diagnostics) to optimize concrete quality for construction needs.
Key Points Explained:
-
System Components and Workflow
- Measuring Device Location: The weighing system is installed between the hopper and mixing cylinder to intercept raw materials before mixing.
- Material Flow: Cement, water, sand, and gravel pass through the measuring device, which captures weight data for each component.
-
Core Technologies
- High-Precision Sensors: These sensors monitor material weights in real-time, transmitting data to the control system. Example: Load cells detect weight changes with minimal latency.
- Computer Control: Advanced algorithms process sensor data to adjust material proportions dynamically, ensuring mix consistency.
-
Control and Adjustment
- Central Control System: Acts as the "brain," managing loading, weighing, and discharging. It cross-checks sensor data against preset ratios (e.g., 1:2:3 for cement:sand:gravel).
- Error Mitigation: Achieves ≤2% error rate by recalibrating flows when deviations occur—critical for meeting construction standards like ASTM C94.
-
User Interface and Diagnostics
- Touchscreen Operation: A 13.5-inch HD touchscreen allows operators to input mix designs and monitor batches.
- AI Integration: The system flags anomalies (e.g., sensor drift) and suggests fixes, reducing downtime.
-
Quality Assurance
- Real-Time Adjustments: If sand exceeds target weight, the system reduces its flow while compensating with other materials.
- Construction Compliance: Ensures concrete meets strength and slump requirements by maintaining precise ratios.
-
Practical Benefits
- Efficiency: Automating batching cuts manual measurement errors and speeds up production.
- Scalability: Adaptable to varying mix designs, supporting projects from sidewalks to high-rises.
By merging hardware precision with smart software, the system exemplifies how automation elevates both accuracy and operational ease in concrete production.
