300 TPH Limestone Crushing Solution in Mexico

Client Profile

Our client is a leading construction materials supplier in Mexico, specializing in high-quality aggregates for infrastructure projects. Facing rising demand for manufactured sand (M-Sand) from limestone, they sought a reliable, high-capacity crushing solution.

Project Overview

• Material: Limestone (compressive strength: 120–150 MPa)
• Feed Size: ≤650mm
• Output Capacity: 300 TPH
• Final Products:
  • 0–5mm (M-Sand for concrete)
  • 5–20mm (road base)
  • 20–40mm (coarse aggregate)

Challenges

1. Strict Gradation Requirements: Needed precise control over sand particle shape and fines content.
2. Equipment Durability: Limestone’s abrasiveness demanded wear-resistant crushers.
3. Space Constraints: Compact layout for limited quarry footprint.

Solution: Liming’s Turnkey Crushing Line

1. Primary Crushing – C6X Jaw Crusher

• Model: C6X160
• Role: Coarse crushing of raw limestone (≤650mm → ≤250mm).
• Advantage: Eccentric forged shaft and wedge adjustment for long lifespan.

2. Secondary Crushing – HPT Hydraulic Cone Crusher

• Model: HPT300
• Role: Intermediate crushing (250mm → ≤50mm).
• Advantage: Multi-cylinder hydraulic system ensures stable output and overload protection.

3. Tertiary Crushing & Sand Making – VSI6X Sand Maker

• Model: VSI6X1263
• Role: Producing 0–5mm M-Sand with optimal cubical shape.
• Advantage: Patented “Rotor-4” design reduces wear by 30% vs. conventional impact crushers.

4. Screening – S5X Vibrating Screen

• Model: S5X3075-3 (3 decks)
• Role: Precise separation of 0–5mm, 5–20mm, and 20–40mm aggregates.
• Advantage: High-frequency vibration for 95% screening efficiency.

Supporting Equipment:

• Belt Conveyors: EP800/4 (10 units for material transfer).
• Dust Control: Pulse-jet bag filter system (compliance with Mexico’s environmental standards).

Technical Highlights

• Automation: Centralized PLC control for real-time monitoring.
• Energy Saving: HPT crusher reduces power consumption by 15% vs. traditional cone crushers.
• Eco-Friendly: VSI6X’s low noise (<75dB) and sealed design minimize dust.

Results

• Production Capacity Achieved: 320 TPH (exceeding target by 6.7%).
• Sand Quality: M-Sand met ASTM C33 standards for concrete.
• Cost Savings: Reduced replacement part costs by 40% (thanks to LHM’s alloy wear plates).

Client Feedback

“Liming’s team delivered a seamless installation within 6 weeks. The VSI6X’s output quality eliminated our need for washing equipment, saving us $200,000 annually. We plan to expand with another LHM line soon!”
