The beneficiation of iron ore involves crushing, grinding, magnetic separation, flotation, and other processes to upgrade low-grade ore into high-quality raw material. A well-designed crushing-sand production line is critical for efficient processing.
1. Primary Jaw Crusher:
– Model: PE-1200×1500
– Feed size: ≤1000mm
– Capacity: 400-800 t/h
– Power: 160-220 kW
2. Secondary Cone Crusher:
– Model: HPT300
– Max feed: 230mm
– Output size: 19-38mm
– Capacity: 180-360 t/h
3. Tertiary Impact Crusher (for sand making):
– Model: VSI6X1263
– Rotor speed: 1000-1400 rpm
– Sand yield: 200-350 t/h
4. Vibrating Screen:
– Deck size: 3YK3070 (3 decks)
– Screening efficiency: ≥90%
A typical 500tph iron ore processing line includes:
– Primary crushing → Secondary crushing → Pre-screening → Tertiary sand making → Final screening → Magnetic separation.
Q1: What’s the ideal moisture content for iron ore crushing?
A: Below 5% to prevent clogging in crushers and screens.
Q2: How to reduce over-crushing?
A: Use multi-stage screening with closed-circuit crushing.
Project: Liaoning Iron Ore Plant (China)
