Dahua Heavy Industry Launches GC Gyratory Crusher and PLS Sand Maker for Hard Rock Mining

Addressing the Core Challenges of Hard Rock Primary Crushing

For decades, metal mining operations have struggled with persistent bottlenecks at the primary crushing stage. High-hardness ores such as iron, copper, gold, and manganese present significant challenges: crushing efficiency is often inadequate, production targets remain elusive, oversized feed materials cause frequent blockages and jamming, equipment failures lead to excessive downtime, and inconsistent product sizing directly undermines downstream grinding and concentration efficiency. These issues have long constrained the scalability, cost-effectiveness, and operational continuity of large-scale mining operations. Recognising these industry-wide pain points, Dahua Heavy Industry has introduced a targeted solution: the GC Series gyratory crusher, specifically engineered for the demanding conditions of metal mining. With capacities ranging from 2,000 to 8,880 tonnes per hour, the GC Series is designed to meet the throughput requirements of million-tonne-per-year mining operations. While such high-capacity solutions represent significant engineering achievements, OCP Mechanical Company recognises that not every operation requires the scale or investment associated with these large-scale systems. With over 40 years of manufacturing experience, we offer practical, cost-effective crushing solutions tailored to medium-capacity operations, backed by factory-direct pricing and round-the-clock technical support.

GC Gyratory Crusher: Engineered for High-Hardness Ores and Continuous Production

The GC Series gyratory crusher represents a significant advancement in primary crushing technology for metal mining applications. At its core is an innovative large-angle, deep-crushing chamber design combined with an extended, high-efficiency crushing face. This unique cavity configuration substantially improves feed adaptability, enabling the crusher to accept extra-large feed sizes while enhancing the compressive and attrition forces applied to the material. The result is seamless, continuous processing of even the hardest metal ores. To withstand the extreme abrasion and impact forces generated by high-hardness ores, all critical wear components are manufactured from high-chromium alloy materials with exceptional impact resistance and wear life. The crusher body itself is constructed using an integral cast steel framework, delivering the structural rigidity needed to endure the high-frequency impact and vibration inherent in hard rock crushing. This robust construction effectively prevents deformation and cracking, ensuring reliable performance in the high-dust, high-load conditions typical of mine environments.

Intelligent Systems Eliminate Blockages and Reduce Downtime

One of the most persistent problems in primary crushing is material blockage caused by oversized feed or poorly designed chambers. The GC Series addresses this through an optimised streamlined chamber design that reduces material flow resistance, ensuring smooth feeding, crushing, and discharge. This is complemented by an intelligent anti-blockage control system that monitors material movement in real time and automatically adjusts the crushing rhythm to prevent jamming, material buildup, and motor overload. The system enables 24-hour continuous operation, significantly improving plant utilisation and reducing unproductive downtime. For mining operations where every hour of lost production represents substantial revenue, this capability translates directly to improved profitability and production predictability.

Modular Design and Hydraulic Adjustment Simplify Maintenance and Reduce Costs

Maintenance complexity and high labour costs have long been significant cost drivers in mining operations. The GC Series addresses this through a fully automatic hydraulic adjustment system that enables precise, rapid closed-side setting changes without manual intervention, accommodating varying product size requirements. The entire machine features a modular, integrated design with a logical, accessible layout that simplifies routine inspections, troubleshooting, and component replacement. All wear parts are factory-standardised with uniform specifications and complete interchangeability, reducing procurement complexity and replacement costs. This comprehensive approach to serviceability minimises downtime, lowers maintenance intensity, and helps mining operations compress their overall operating costs.

PLS Vertical Shaft Impact Crusher: Complementing the Primary Circuit

Beyond the GC gyratory crusher, Dahua has also introduced the PLS vertical shaft impact crusher, designed to complement primary crushing circuits in hard rock applications. The PLS series is engineered for tertiary crushing and manufactured sand production, delivering consistent, cubical product shapes essential for high-quality aggregates and downstream processing. While the GC Series handles the heavy-duty primary reduction of run-of-mine ore, the PLS VSI crusher excels at shaping and fine crushing, producing specification-grade products for concrete, asphalt, and industrial applications. The combination of GC gyratory crushers for primary reduction and PLS VSI crushers for tertiary shaping provides a complete hard rock processing solution capable of handling the most demanding metal mining applications. For quarry operators and mining companies, this integrated approach delivers consistent product quality, lower operating costs, and improved plant availability.

Market Context: The Growing Demand for High-Capacity, Intelligent Crushing

The introduction of the GC Series and PLS crushers reflects broader industry trends toward higher capacity, greater automation, and improved reliability in mineral processing. As global demand for metals and minerals continues to rise—driven by infrastructure development, the energy transition, and industrial growth—mining operations are under increasing pressure to maximise throughput while controlling costs. The shift toward intelligent, data-driven mining is accelerating, with equipment manufacturers integrating sensors, automation, and predictive maintenance capabilities into their products. For quarry operators and mining companies, this means that modern crushing equipment must deliver not only high capacity but also the intelligence to optimise performance, reduce downtime, and extend wear life.
