Iron ore beneficiation plants in Asia rely heavily on efficient crushing and sand-making production lines to process raw materials into high-quality aggregates. These lines typically include jaw crushers, cone crushers, vertical shaft impactors (VSIs), and vibrating screens, tailored to handle hard ores like hematite and magnetite.
1. Primary Jaw Crusher: Processes large iron ore lumps (up to 1,500mm) into smaller fragments (150–300mm). Models like PE-1200×1500 offer capacities of 400–800TPH.
2. Secondary Cone Crusher: Fine-crushing to 20–50mm. Hydraulic models (e.g., HPT300) feature adjustable discharge settings and throughputs up to 500TPH.
3. Tertiary VSI Crusher: Produces cubical sand (0–5mm) with high gradation for concrete. Parameters include rotor speed (1,500–2,500 RPM) and power (200–400 kW).
| Equipment | Model | Feed Size | Output Size | Capacity |
|---|---|---|---|---|
| Jaw Crusher | PE-1200×1500 | ≤1,500mm | 150–300mm | 400–800TPH |
| Cone Crusher | HPT300 | ≤350mm | 20–50mm | 250–500TPH |
| VSI Crusher | S8-1145 | ≤50mm | 0–5mm | 100–300TPH |
Multi-deck vibrating screens (e.g., 3YK3070) classify crushed ore into precise fractions (±5% tolerance). High-frequency screens optimize manufactured sand fineness modules (FM: 2.6–3.0).
