Technical Deep Dive: Core Process Flow
Step 1: Efficient Crushing & Screening
Adopt the "three-stage one closed circuit" configuration.
• Mechanism: Coarse crushing followed by medium and fine crushing stages.
• Equipment: Baichy Jaw Crusher (Primary) and Hydraulic Cone Crusher (Secondary/Tertiary) work in tandem to reduce particle size from ≤800mm to a final ≤12mm, minimizing energy consumption for the subsequent grinding stage.
Step 2: Precision Grinding & Classification
The Φ4.5×6.5m overflow ball mill forms a high-efficiency closed-circuit system with a cyclone group.
• Result: Achieves a grinding fineness of -200 mesh (accounting for 75%), ensuring optimal mineral liberation for superior grade separation.
Step 3: Multi-Stage Magnetic Separation
Utilizing staged separation (Coarse, Fine, and Scavenging separation) to tackle complex iron ore bodies.
• Key Tech: The Vertical Ring High Gradient Magnetic Separator provides a field strength of ≥1.2T, effectively reducing impurity content while maintaining a comprehensive recovery rate of ≥85%.
Step 4: Smart Dehydration & Control
The combination of a concentrator and filter press ensures the final concentrate moisture is maintained below 10%, optimized for international transport.
• Intelligent System: The entire line is integrated with a DCS Central Control System, providing real-time monitoring of energy consumption and output, significantly reducing manual intervention costs.
