A well-designed iron ore beneficiation plant integrates crushing, grinding, and classification to upgrade low-grade ore. The core equipment includes jaw crushers, cone crushers, ball mills, and magnetic separators. Below is a streamlined sand-making line for producing high-quality aggregates from iron ore tailings.
1. Primary Jaw Crusher
– Model: PE600×900
– Feed Size: ≤500mm
– Capacity: 50–160 t/h
– Power: 75 kW
2. Secondary Cone Crusher
– Model: HPT300
– Max Feed: 240mm
– Output: 70–400 t/h
– Power: 315 kW
3. Vertical Shaft Impact Crusher (Sand Maker)
– Model: VSI1140
– Throughput: 120–360 t/h
– Product Fineness: 0–5mm (adjustable)
4. Magnetic Separator (for iron recovery)
– Type: CTB1230
– Field Intensity: 1500 Gauss
Raw iron ore → Primary crushing → Secondary crushing → Screening → Sand making → Magnetic separation → Finished aggregates (3–5mm sand, 5–10mm gravel).
Q1: How to reduce dust in crushing?
A: Install dust collectors (e.g., pulse bag filters) at transfer points.
Q2: Can tailings replace natural sand?
A: Yes, after grading and impurity removal, tailings sand meets ASTM C33 standards.
Project: Liaoning Iron Ore Plant, China (2022)
– Output: 500 t/h artificial sand from tailings.
– Solution: PE900×1200 jaw crusher + HST315 cone crusher + VSI1145 sand maker. Resulting sand achieved ≤3% moisture and ≥95% iron recovery rate.
