Project Success 2026

Achieving 85% Yield in Hard Rock Fine Crushing with HSM Hydraulic Technology

How the 2PGY Series redefined production standards for a leading mining enterprise.

Project Overview

A large-scale mineral processing facility was struggling with inefficient tertiary crushing. Their existing equipment produced excessive powder (over 18%) and failed to meet the strict cubic shape requirements for high-grade aggregate. HSM replaced their outdated circuit with the Large Hydraulic Double Roller Crusher (2PGY Series) to implement intelligent static pressure extrusion.

Key Performance Results

Performance Metric Before HSM Upgrade After HSM Hydraulic Roller
Finished Product Yield ~60% 85% (Optimal Gradation)
Energy Consumption Standard High Usage Reduced by 40%
Powder/Fines Content 15% – 18% Dropped to 5%
Maintenance Frequency Every 15-20 Days Extended to 6+ Months

“Integrating HSM’s hydraulic roller technology transformed our profitability. By reducing energy costs and virtually eliminating excess waste powder, we now produce a premium cubic aggregate that consistently exceeds national infrastructure standards.”
