1. PAINPOINT DRIVEN OPENING

Is your gold processing plant struggling with the foundational stage of mineral liberation? Inefficient primary crushing directly undermines your entire operation's profitability and throughput. Consider these common challenges:
Excessive Downtime for Maintenance: Frequent liner changes and unplanned repairs on your primary crusher halt your milling circuit, costing thousands per hour in lost production.
Inconsistent Feed Size to SAG/Ball Mills: Poorly sized crusher product creates bottlenecks in downstream grinding, reducing mill efficiency and increasing specific energy consumption (kWh/ton).
High Abrasion Costs in Hard Rock Formations: The extreme abrasiveness of quartzrich gold ore leads to rapid wear on crusher components, driving up your cost per ton in replacement parts and labor.
Unreliable Performance with Variable Ore Grades: Fluctuations in ore hardness and clay content can cause plugging or capacity drops in crushers not designed for such variability.

Are you seeking a crushing solution that delivers consistent throughput, reduces total operating costs, and provides reliable firststage reduction for your gold recovery circuit?

2. PRODUCT OVERVIEW

The GC600HD Gyratory Crusher is engineered as a highcapacity primary crushing solution specifically for gold ore processing plants. It is designed to accept runofmine (ROM) feed directly from the haul trucks, providing the critical first stage of size reduction.

Operational Workflow:
1. ROM ore (up to 1500mm) is dumped directly into the crusher’s feed hopper.
2. A controlled gyrating motion of the mantle against the concave liners applies compressive force, breaking the ore by pressure.
3. The crushed product discharges via gravity through the bottom of the crusher, with a typical product size of 150250mm for direct feed to a secondary crushing circuit or SAG mill.

Application Scope: Ideal for hightonnage greenfield projects or expansions requiring reliable primary crushing of hard and abrasive gold ores (e.g., quartz veins, sulphidebearing rock). Limitations: Not suitable for sticky, highclay ores without prior grizzly screening; requires a stable concrete foundation and significant headroom for installation.
