1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable throughput in your primary crushing circuit? For plant managers and engineering contractors, the initial size reduction of gold ore is a critical bottleneck with direct consequences for downstream recovery and profitability. Common challenges include:

Excessive Downtime for Maintenance: Frequent liner changes and unplanned repairs on inadequate crushers halt your entire processing line, costing thousands per hour in lost production.
Inconsistent Feed Size Reduction: Variable ore hardness and feed size can cause plugging or erratic output, overloading your SAG or ball mill circuits and reducing overall gold recovery efficiency.
High Energy Consumption per Ton: Inefficient crushing technology directly translates to unsustainable power costs, a primary concern in remote mining operations.
Premature Wear Part Failure: Abrasive gold ores, particularly those with high silica content, can devastate crusher components not engineered for such duty, leading to runaway spare parts expenses.

Is your primary crushing station a source of cost volatility rather than a pillar of reliable throughput? The solution lies in selecting equipment engineered specifically to transform these operational challenges into controlled, efficient processes.

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This product line encompasses a range of robust, stationary and modular jaw crushers engineered as the first stage in hard rock gold ore comminution. Designed for high availability and maximum yield on abrasive feeds, this equipment forms the reliable foundation of your mineral processing plant.

Operational Workflow:
1. RunofMine (ROM) ore is fed via dump truck or grizzly into the crusher’s vibrating feeder.
2. Ore is gripped and crushed between a fixed and a mechanically actuated moving jaw plate.
3. The crushed product discharges onto the main conveyor, sized to specification (typically below 150mm), ready for secondary crushing or direct feed to a SAG mill.

Application Scope: Primary crushing of hard rock gold ores (quartz veins, sulphidebearing ores), runofmine material with compressive strengths up to 350 MPa. Suitable for both greenfield installations and retrofit upgrades.

Key Limitations: Not designed for wet, sticky ores without prior scalping; maximum feed size is defined by crusher model dimensions.
