200 TPH Lithium Ore Crushing Plant In Nigeria

Client Profile

Client Location: Lagos, Nigeria
Mineral Type: Lithium ore (spodumene)
Production Requirement: 200 tons per hour
End Use: Lithium concentrate for battery manufacturing

Project Overview

A Nigerian mining company sought to establish a lithium ore processing line to meet growing global demand for battery raw materials. The project required robust equipment capable of handling abrasive lithium ores while maintaining consistent 200 TPH output with low maintenance downtime.

Key Challenges

1. High Abrasiveness: Lithium ore (Mohs hardness ~6.5-7) accelerates wear on conventional crusher.
2. Strict Gradation: Needed 0-5mm finished sand meeting ISO 14688-1 standards for hydrometallurgy.
3. Climate Conditions: High humidity and dust-prone West African environment demanded corrosion-resistant designs.

Liming Heavy Industry’s Solution

1. Primary Crushing Stage

• Equipment: C6X160 Jaw Crusher
• Capacity: 240 TPH
• Input Size: ≤850mm
• Output Size: ≤200mm
• Advantages:
  • Integrated motor base reduces vibration and extends bearing life by 30%.
  • Eccentric heavy-duty forging shaft handles tough lithium ores without deformation.

2. Secondary Crushing Stage

• Equipment: HPT300 Multi-cylinder Hydraulic Cone Crusher (2 units parallel)
• Capacity: 220 TPH total
• Adjustable Output: 19-38mm
• Advantages:
  • Laminated crushing principle reduces 15% energy consumption vs. conventional cone crusher.
  • PLC-controlled hydraulic system enables real-time CSS adjustment during operation.

3. Sand Making & Shaping Stage

• Equipment: VSI6X1263 Vertical Shaft Impact Crusher
• Sand Yield: 75% of total output (~150 TPH)
• Finished Sand: 0-5mm with ≤3.0 fineness modulus
• Advantages:
  • Four-port rotor design increases throughput by 20% compared to traditional VSI crusher.
  • German-origin SKF bearings ensure 8,000+ operational hours without lubrication intervention.

Supporting Equipment

• Vibrating Feeder: ZSW490×130
• Circular Vibrating Screen: 3YZS2460 (two decks)
• Belt Conveyors: B1400×8.5M (main) + B1000×12M (returns)

• Intelligent Control System: Centralized PLC monitors bearing temperatures (alert threshold: 75°C) and vibration levels (<4mm/s).
• Dust Suppression: Integrated spray nozzles at transfer points keep airborne dust <10mg/m³.
• Quick-Wear Parts: Rotor tips and anvils use proprietary LML (Liming Manganese Alloy) with 3x lifespan vs. standard Mn18Cr2.

Project Results

• Production: Achieved stable 210 TPH output (105% of target) with 93% uptime.
• Product Quality: 0-5mm sand accounts for 78% of total yield, exceeding the client’s 70% expectation.
• Cost Savings: Wear part replacement frequency reduced by 40%, lowering OPEX by $18,000/month.
