30-bin automated batching line for monolithic refractory materials
1. Multi-Silo Collaborative Storage System
Powder and Aggregate Silos: Integrates 30 standardized silos, adaptable to materials of varying densities (e.g., high-alumina clinker, silica fume). Equipped with level gauges, vibrators, and air-blast clearing devices to ensure stable material delivery.
Ultrafine Material Handling: Features disc feeders and pneumatic control valves to solve the floating tendency of lightweight materials.
2. Composite Arch-Breaking and Anti-Clogging Technology
Dual-Mechanism Linkage: Addresses the bridging propensity of powders through integrated pneumatic air blasting (solenoid valve assembly) combined with mechanical vibration for proactive arch-breaking intervention.
Differentiated Design: Aggregate silos employ high-frequency vibration for forced discharge; powder silos incorporate WAM real-time level monitoring paired with air disc flow aids to guarantee continuous material supply.
3. 0.5% High-Precision Segmented Metering
Dual-Stage Speed Control Strategy: Screw conveyors (variable frequency drive) for coarse feeding, followed by vibratory feeders for fine flow rate adjustment, achieving dynamic error of ≤ ±0.5%.
Closed-Loop Feedback System: Compression sensors (0.5‰ accuracy) transmit real-time data to Siemens PLC, enabling precise cutoff via pneumatic butterfly valves or sector valves to maintain formulation consistency.
4. Full-Process Enclosed Dust collect System
Source Sealing: Physical isolation of dust throughout silos, conveyor belts, and mixers from feeding to discharge.
High-Efficiency Centralized Dust Extraction: Pulse-jet baghouse dust collectors cover all stages from material charging to packaging, with galvanized ductwork and corrugated flexible hoses for targeted capture of fugitive particulates.
5. Flexible Intelligent Production Line Scheduling
Multi-Silo Collaborative Configuration: Combines powder and aggregate silos to support simultaneous production of up to 30 raw materials, with seamless switching between multiple formulations.
Central Control Platform: Siemens PLC integrated with a 15-inch touchscreen enables recipe retrieval, variable frequency drive synchronization, and production traceability, reducing manual intervention by 30%.
6. Robotic Full-Stack Palletizing Integration
Packaging and Palletizing Integration: Open-mouth bagging machines (25 kg per bag) → automatic folding and sewing → Estun robotic single-gripper palletizing.
Intelligent Sorting and Positioning: Compression shaping machines combined with pre-palletizing conveyors for alignment correction; ton-bag mechanisms assist in stacking small bags, boosting efficiency by 60%.
