Magnetite sand, a high-density iron ore, requires specialized crushing and screening equipment for efficient extraction. The typical production line includes jaw crushers, cone crushers, vibrating screens, and magnetic separators. Below is a streamlined process:
1. Primary Crushing: Raw magnetite sand is fed into a jaw crusher (e.g., JC110 with 110kW power, 50–250mm feed size) for coarse reduction.
2. Secondary Crushing: A hydraulic cone crusher (e.g., HPT300, 220kW, output size 10–30mm) further breaks down the material.
3. Screening: A multi-deck vibrating screen (e.g., 3YK3070, 15–50t/h capacity) classifies particles by size.
4. Magnetic Separation: A high-gradient magnetic separator (e.g., CTB1230, 1.8T magnetic intensity) isolates magnetite from impurities.
| Equipment | Model | Power | Capacity |
|---|---|---|---|
| Jaw Crusher | JC110 | 110kW | 50–250t/h |
| Cone Crusher | HPT300 | 220kW | 100–350t/h |
| Vibrating Screen | 3YK3070 | 15kW | 15–50t/h |
| Magnetic Separator | CTB1230 | 7.5kW | 20–40t/h |
Q: How to minimize dust in magnetite processing?
A: Install dust collectors (e.g., pulse bag filters) at transfer points and use water spray systems.
Q: What’s the ideal feed size for magnetic separators?
A: ≤3mm for optimal recovery; pre-screening
