High-Alumina River Pebble Sand Making Project

Location: Southeast Asia | Throughput: 180-200 TPH | Material: High-Silica River Pebbles

1. Client Challenges & Pain Points

Double-roller sand making machine site

The client, a leading infrastructure contractor, faced significant operational hurdles while processing river pebbles with a silica content exceeding 78%. Their existing Vertical Shaft Impact (VSI) crusher system resulted in:

Critical Wear Costs

Wear parts required replacement every 120 operating hours due to high abrasiveness, leading to unsustainable maintenance expenses.

Inconsistent Grading

Excessive generation of ultra-fine dust (<0.075mm) compromised the compressive strength of the high-grade concrete required for the project.

2. The HSM Engineering Solution

After a comprehensive material analysis, HSM engineers deployed the 2PGY1500×1200 Hydraulic Double Roller Crusher. The system was customized with three core technologies:

Advanced Laminar Crushing: Utilizing static hydraulic pressure to crush material layers rather than high-speed impact, drastically reducing liner wear.
PLC-Integrated Gap Adjustment: Real-time monitoring allowed operators to maintain a constant 3mm gap, ensuring a stable fineness modulus (2.6-3.0).
5th Gen Alloy Liners: High-chromium manganese alloy roller skins specifically treated for high-silica environments.

3. Economic & Operational Performance

Previous VSI System

Liner Life: 120 Hours

Energy Cost: $1.15 / Ton

Fines (<0.075mm): 18% – 22%

HSM 2PGY System

Liner Life: 850+ Hours

Energy Cost: $0.82 / Ton

Fines (<0.075mm): 8% – 10%

Final Result

The implementation of HSM hydraulic technology allowed the client to save over $120,000 annually in spare parts and downtime labor, while consistently producing premium-grade sand that exceeded project specifications.
