Process Flowchart
Process Design Solution
The plant operates through a three-stage sequential system:
1. Pre-Screening & Crushing Stage
Raw ore undergoes primary classification through a 918-type vibrating screen with 50mm grizzly bars, effectively removing oversize material. Optimally sized ore (-50mm) feeds into three parallel PC350×500 hammer crushers, achieving 95% < 1.5 mm particle size through coordinated operation, ensuring consistent throughput while maintaining precise output control.
2. Gravity Concentration Stage
Crushed material is discharged onto nine 4500×1850mm shaking tables operating in a parallel configuration. This multi-deck arrangement provides 18 separation surfaces for maximum tantalite recovery in the 0.02- 2 mm particle size range, with adjustable stroke length (10-25 mm) and frequency (250- 350 rpm) for optimal mineral separation.
3. Magnetic Upgrading Stage
Gravity concentrates undergo sun-drying before processing through the 3PC-500 three-disc magnetic separator. This innovative configuration achieves three-stage separation in a single pass (1700-20000GS adjustable), effectively removing ferrous impurities while recovering paramagnetic tantalite minerals.
Core Equipment Selection
Pre-Screening: 918 Vibrating Screen (900×1800mm deck, 2.2kW motor, 50mm grizzly spacing)
Crushing System: 3×PC350×500 Hammer Crushers (15kW each, impact-plate gap adjustable 1-15mm)
Concentration: 9×4500×1850mm Shaking Tables (1.1kW motors, deck angle 2-5° adjustable)
Final Upgrading: 3PC-500 Magnetic Separator (0.75kW drive, 1.5kW excitation power)

Customer Questions & Our Answers
Q1. Why use parallel hammer crushers instead of one large unit?
A: Our triple-hammer crusher configuration delivers:
- Precision Grinding: Maintains strict 0-1.5 mm output (±0.3mm tolerance) critical for gravity separation
- Load Balancing: Each crusher operates at 70% capacity for 300% system redundancy
- Energy Efficiency: Small crushers consume 30% less power per ton at fine grinding ranges
- Maintenance Advantage: Isolate one unit without shutting down production
Q2. What’s the operational value of grizzly bars on the vibrating screen?
A: The 50mm grizzly spacing provides:
- Pre-classification: Directs -50mm material straight to hammer crushers
- System Protection: Blocks oversize rocks that cause crusher jamming
- Throughput Optimization: Increases effective capacity by 20% vs direct feeding
- Wear Reduction: Extends hammer crusher liner life by 35%
Q3. Why implement dry magnetic separation after shaking tables?
A: Our 3PC-500 triple-disc separator offers:
- Grade Improvement: Achieves 95% purity vs 85% with wet methods
- Water Conservation: Eliminates 5m³/hour water requirement
- Multi-Stage Separation: Processes paramagnetic/ferrous/non-magnetic minerals simultaneously
- Arid Advantage: Ideal for Bolivia’s 4,000m altitude water-scarce environment
Q4. What justifies using nine shaking tables?
A: This configuration ensures:
- Capacity Security: Each table processes just 55% of rated capacity for stable operation
- Grade Control: Multiple cleaning stages boost Ta₂O₅ recovery to 92%
- Flexible Operation: Adjust individual decks for ore variability (2-5° tilt range)
- Future Expansion: Simply add tables for 20TPH capacity
Q5. Why hammer crushers instead of jaw + cone combination?
A: This selection provides:
- Size Advantage: Processes -100mm feed directly without primary crushing
- Cost Efficiency: $18/ton operating cost vs $32/ton for conventional crushing circuit
- Space Savings: 60% smaller footprint than two-stage systems
- Specialization: Optimized for brittle tantalite’s cleavage planes
Pro Tip: Our hammer crushers feature reversible rotors – simply flip hammers when one side wears to double service life.
Q6: How does the dry process compare environmentally?
- Zero process water contamination risk
- 85% lower energy use than conventional tantalite plants
- Magnetic separation creates no chemical tailings
