Magnetite ore beneficiation in India typically involves crushing, grinding, magnetic separation, and sand-making processes. A well-designed production line ensures high efficiency and low operating costs.
1. Jaw Crusher (Primary Crushing)
– Model: PE600×900
– Feed Size: ≤500mm
– Capacity: 50-160 t/h
2. Cone Crusher (Secondary Crushing)
– Model: HPT300
– Max Feed Size: 240mm
– Output Size: 10-30mm
3. Vertical Shaft Impact Crusher (Sand Making)
– Model: VSI1140
– Capacity: 70-140 t/h
– Finished Sand Size: 0-5mm
4. Magnetic Separator
– Model: CTB1230
– Magnetic Intensity: 1500 Gauss
1. Primary crushing → Secondary crushing → Screening → Magnetic separation → Sand making → Grading
Q1: What is the ideal feed size for magnetite ore?
A: Below 500mm for primary crushing to avoid blockages.
Q2: How to improve sand yield in magnetite processing?
A: Use a VSI crusher with adjustable rotor speed for better shaping.
Q3: What maintenance is required for magnetic separators?
A: Regular cleaning of magnetic drums and inspection of belts every 500 hours.
Project Location: Odisha, India (2012)
Ore Type: Magnetite (Fe3O4 content ~45%)
Equipment Used: PE600×900 Jaw Crusher + HPT300 Cone Crusher + VSI1140 Sand Maker
Output: 120 t/h finished sand (0-5mm) with Fe grade >65% after beneficiation.
