Philippines 160TPH Silica Sand Production Line

Client Profile

A mining company in the Philippines sought to process silica (SiO₂) into high-purity artificial sand for construction and industrial use. Their key requirements included:

• Material: Silica (hard, abrasive)
• Capacity: 160 tons per hour
• Output: 0–5mm fine sand with low powder content
• Challenge: Balancing high yield with precise particle shape for commercial value.

Project Overview

Liming Heavy Industry designed a turnkey silica sand production line combining crushing, shaping, and screening stages to maximize efficiency and minimize wear costs.

Challenges

1. Silica’s Abrasiveness: Rapid equipment wear risk.
2. Shape Control: Meeting ISO gradation standards for commercial sand.
3. Dust Management: Reducing fine powder during crushing.

Solution: Customized Silica Sand Plant

1. Primary Crushing

• Equipment: C6X Jaw Crusher
• Role: Coarse crushing of raw silica (≤650mm) to ≤150mm.
• Advantage: Integrated motor base and anti-deformation frame for heavy-duty processing.

2. Secondary Crushing

• Equipment: HST Single-Cylinder Hydraulic Cone Crusher
• Role: Further reduces silica to ≤50mm with laminated crushing principle.
• Advantage: Automatic overload protection and low wear costs.

3. Sand Making & Shaping

• Equipment: VSI6X Sand Maker (Key Equipment)
• Role: Transforms crushed silica into well-shaped 0–5mm sand via rock-on-rock/rock-on-iron crushing.
• Advantage: Patented four-port impeller design improves output by 30% versus conventional VSIs.

4. Screening & Grading

• Equipment: S5X Vibrating Screen (2 units)
• Role: Classifies sand into 0–3mm, 3–5mm fractions; returns oversized particles.
• Advantage: Hyperbolic vibration for anti-clogging.

5. Auxiliary Systems

• Dust collector (pulse jet type) to meet eco-standards.
• Belt conveyors (B6X series) with impact-resistant design.

Technical Highlights

• Automated PLC Control: Monitors real-time production data.
• Wear-Resistant Material: Tungsten carbide tips on VSI6X rotor for silica abrasion resistance.
• Zero-Spill Design: Sealed bearings and dust-proof motors.

Results

• Output: 160–170TPH consistently achieved.
• Sand Quality: Cubical shape (≤8% flakiness), ideal for concrete mixes.
• Cost Savings: 40% longer wear life vs. local competitors’ equipment.

Client Feedback

“Liming’s VSI6X sand maker exceeded our expectations—minimal downtime and perfect grain shape. The entire line runs smoothly, and their engineers provided excellent on-site training.”
