Client Profile
A leading mining operator in Nigeria specializing in lead-zinc extraction, seeking to upgrade their processing capacity to 100 tons per hour while reducing downtime and maintenance costs.
Project Overview
Location: Nigeria
Material: Lead-zinc ore (Mohs hardness: 3.5-4)
Feed Size: ≤500mm
Output Size: 0-25mm (adjustable)
Capacity: 100TPH
Application: Mineral processing plant feed
Challenges
- Abrasive ore properties causing rapid wear on conventional crushers
- High humidity environment increasing equipment corrosion risk
- Unstable power supply requiring energy-efficient solutions
- Space constraints demanding compact equipment layout
Solution & Equipment Configuration
Liming Heavy Industry designed a two-stage crushing circuit with intelligent automation:
- Primary Crushing – PE600×900 Jaw Crusher
- Role: Coarse crushing of raw ore ≤500mm → ≤150mm
- Advantages:
- Cast steel frame with reinforced bearings for heavy-load ore
- “V”-shaped cavity design increases throughput by 15%
- Dust-proof motor adapts to Nigeria’s humid conditions
- Secondary Crushing – HST250 Single Cylinder Cone Crusher
- Role: Fine crushing from ≤150mm → 0-25mm
- Advantages:
- Laminated crushing principle reduces wear by 30% vs conventional crushers
- Hydraulic adjustment system allows quick CSS changes
- Integrated dust suppression for cleaner operation
- Auxiliary Equipment:
- GZD960×3800 Vibrating Feeder – Ensures uniform material flow
- 3YZS2160 Vibrating Screen – 3-layer classification with 95% screening efficiency
- Belt Conveyors – Oil-resistant rubber for longevity
Technical Highlights
- Hybrid Power Option: Compatible with diesel generators for power grid instability
- Smart Monitoring: IoT-enabled sensors for real-time wear part diagnostics
- Modular Design: Pre-assembled components reduced installation time by 40%
Results
- Throughput: Consistently achieved 105-110TPH (exceeding target)
- Availability: 98.2% uptime over 12 months
- Energy Efficiency: 35% lower kWh/ton than client’s previous setup
- Maintenance: Wear parts life extended by 20% (HST250 mantle lasts 1,800 hours)
Client Testimonial
“Liming’s PE600×900 jaw crusher and HST250 cone crusher transformed our lead-zinc operation. The automated system cut labor costs by 25%, and the wear-resistant liners reduced our spare parts inventory. This is our most reliable crushing line in Nigeria.”
