Sihyde has successfully delivered a fully automated refractory material batching system for a large-scale refractory production project. Designed according to the customer’s specific production requirements, this customized solution integrates intelligent storage, precision weighing, automatic conveying, dust collection, production management, and robotic palletizing technologies.
By combining advanced automation control and customized process design, the system helps refractory manufacturers improve batching accuracy, increase production efficiency, reduce manual operation, and achieve more stable product quality.
Multi-Silo Intelligent Storage System for Various Raw Materials
The system integrates multiple storage silos designed for different refractory raw materials, including aggregates and fine powders such as high-alumina clinker and silica fume.
Each silo is equipped with intelligent material monitoring and discharge assistance devices, including level sensors, vibration systems, and air-assisted flow devices, ensuring continuous and stable material supply during production.
For ultrafine powders with poor flowability, specialized disc feeders and pneumatic control valves are applied to improve feeding stability and effectively prevent material blockage.
2. Advanced Anti-Blocking Technology for Stable Material Discharge
Different refractory materials have unique flow characteristics and may cause bridging or clogging during storage and discharge.
To solve these challenges, Sihyde applies a combination of mechanical vibration and pneumatic air-blasting technology to effectively break material arches and maintain continuous material flow.
Customized discharge solutions are designed according to different material properties:
Aggregate silos adopt high-frequency vibration systems to ensure smooth discharge.
Powder silos integrate real-time level monitoring and air-assisted flow technology to improve feeding reliability.
This intelligent design ensures stable operation under complex production conditions.
3. High-Precision Automated Weighing and Batching System
The automated batching system adopts a two-stage feeding control strategy to achieve precise raw material dosing.
Coarse feeding is completed through variable-frequency screw conveyors, while fine adjustment is achieved through precision vibratory feeders.
With high-accuracy load cells and Siemens PLC closed-loop control, the system achieves batching accuracy up to ±0.5%, ensuring consistent material ratios and improving final product quality.
Automatic valve control enables precise material cutoff and significantly reduces manual operation errors.
4. Fully Enclosed Dust Collection and Environmental Protection System
To meet modern environmental requirements, the entire production process adopts an enclosed material handling design.
Dust control systems are integrated throughout the complete process, including:
Raw material storage
Material conveying
Mixing operations
Packaging processes
The centralized pulse-jet bag filter dust collection system efficiently captures airborne particles, creating a cleaner production environment, reducing material loss, and improving workplace safety.
5. Intelligent Production Management and Flexible Formula Control
The system supports intelligent production scheduling and multi-formula management.
With multiple silo configurations, the production line can handle various raw materials and quickly switch between different product formulations.
The Siemens PLC control system with industrial touchscreen interface enables:
Recipe management
Real-time production monitoring
Equipment status tracking
Automated parameter adjustment
This improves production flexibility, enhances operational efficiency, and reduces dependence on manual processes.
