Iron ore beneficiation involves crushing, grinding, magnetic separation, and other processes to upgrade low-grade ore. A well-designed crushing-sand production line is critical for efficient processing. Below is a typical setup for such a system:
1. Jaw Crusher (Primary Crushing)
– Model: PE-600×900
– Feed Size: ≤500mm
– Capacity: 50–160 t/h
– Power: 55–75 kW
2. Cone Crusher (Secondary Crushing)
– Model: HPT300
– Max Feed Size: 240mm
– Capacity: 120–400 t/h
– Power: 220 kW
3. Vertical Shaft Impact Crusher (Sand Making)
– Model: VSI-1140
– Feed Size: ≤50mm
– Capacity: 60–300 t/h
– Power: 250 kW
4. Vibrating Screen
– Model: 3YK3070
– Layers: 3
– Screen Area: 21m²
– Power: 15 kW
1. Primary crushing with a jaw crusher reduces iron ore to ≤150mm.
2. Secondary crushing via a cone crusher further reduces size to ≤40mm.
3. Sand-making stage with a VSI crusher produces fine aggregates (0–5mm).
4. Screening separates products into different grades for concrete or construction use.
Q1: What is the ideal moisture content for iron ore crushing?
A: Below 5% to avoid clogging and ensure efficiency.
Q2: How to reduce wear on crushers?
A: Use high-chrome blow bars and regular lubrication maintenance.
Q3: Can this line process other ores?
A: Yes, with adjustments for hardness and abrasiveness (e.g., granite, basalt).
A project in Australia processed 500 t/h of hematite ore using the above configuration, achieving a final sand yield of 35% with <3% powder content, meeting
