2026 Operational Milestone
High-Silica River Stone Crushing: A 250 TPH Success Story
Engineered for Extreme Abrasiveness and High-Strength Concrete Sand Production
Background & Challenge
In early 2026, a major construction group in Southeast Asia faced a critical challenge: processing hard river stone (high silica content) into premium manufactured sand. Traditional sand makers suffered from excessive wear and high maintenance downtime. They needed a robust, high-pressure solution capable of delivering a consistent 0-4mm output with a focus on particle cubicity and minimal fines.

Optimization Results
| Metric | Previous VSI Crusher | HSM Hydraulic Solution |
|---|---|---|
| Wear Part Life | 7-10 Days | 45-60 Days |
| Energy Per Ton | 2.8 kWh/t | 1.9 kWh/t |
| Finished Product Rate | 65% (within 0-5mm) | 88% (within 0-4mm) |
Solution Strategy
Double Roller Crusher
HSM engineers implemented the 2PGY-1512 Hydraulic Double Roller Crusher as the secondary fine-crushing stage. By utilizing high-pressure extrusion, the river stones were fractured along natural grain boundaries, resulting in a cubic particle shape that significantly improves concrete workability. The intelligent hydraulic system automatically adjusted the discharge gap to compensate for roller wear, ensuring zero variance in product size over long production cycles.
“The shift to HSM’s hydraulic technology has transformed our bottom line. We reduced our replacement part frequency by nearly 80%, and the lower power consumption is a major win for our sustainability goals in 2026.”
