Zimbabwe 120 TPH Magnesium Ore Processing Plant

Client Profile

A mining company in Zimbabwe sought a reliable solution to process 120 TPH of magnesium ore into high-quality aggregates for industrial applications. The client needed durable, high-efficiency equipment to handle abrasive ore while minimizing downtime.

Project Overview

• Location: Zimbabwe
• Material: Magnesium ore (Mohs hardness: ~4-5)
• Capacity: 120 tons per hour
• Final Output: 0-30mm graded aggregates

Challenges

1. High abrasiveness of magnesium ore required wear-resistant equipment.
2. Strict output size (0-30mm) demanded precise crushing and screening.
3. Local infrastructure limitations necessitated robust, low-maintenance machines.

Solution: Customized Liming Crushing & Screening Line

1. Primary Crushing: PE750×1060 Jaw Crusher

• Role: Coarse crushing of raw magnesium ore (≤500mm → 150mm).
• Advantages: High crushing ratio, durable manganese steel plates, low energy consumption.

2. Secondary Crushing: HST250 Single-Cylinder Hydraulic Cone Crusher

• Role: Further reduction (150mm → 30mm).
• Advantages: Hydraulic adjustment for precise output, laminated crushing principle for cubic-shaped aggregates.

3. Screening: 3YZS2460 Vibrating Screen

• Role: Grading crushed ore into 0-10mm, 10-20mm, and 20-30mm sizes.
• Advantages: Multi-layer screening, high efficiency, and noise reduction design.

Supporting Equipment:

• Belt Conveyors (B1000×20m): Seamless material transfer between stages.
• Electric Control System: Automated operation for safety and efficiency.

Technical Highlights

• Wear-resistant Materials: Critical parts (e.g., jaw plates, mantle) use Mn18Cr2 alloy for extended lifespan.
• Energy Efficiency: HST Cone Crusher reduces power consumption by 15% vs. traditional crushers.
• Modular Design: Quick installation and minimal foundation requirements for remote sites.

Project Results

• Achieved Capacity: Steady 120 TPH output, meeting client’s production targets.
• Product Quality: 95% of output met 0-30mm specs with low flakiness.
• Operational Efficiency: Over 85% uptime thanks to Liming’s low-maintenance design.

Client Feedback

“Liming’s team provided end-to-end support, from equipment selection to commissioning. Their PE Jaw Crusher and HST Cone Crusher handled our tough magnesium ore without breakdowns. The plant now runs smoothly, and the after-sales service is excellent.”
