1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent feed size, excessive liner wear costs, or unplanned downtime from equipment failure? Inefficient primary crushing directly impacts your entire recovery circuit, leading to:
Throughput Bottlenecks: Mismatched crusher output can choke downstream milling processes, costing hundreds of production hours annually.
Spiraling Maintenance Costs: Frequent jaw liner or mantle changes on standard crushers halt operations and incur significant labor and parts expenses.
High Energy Inefficiency: Older crushing technology consumes disproportionate power per ton of ore processed, eroding profit margins.
Unpredictable Product Size: Poorly controlled output size distribution reduces grinding circuit efficiency and can affect cyanidation kinetics.

Is your primary crushing stage a reliable asset or a recurring liability? The solution lies in selecting equipment engineered specifically for the abrasive, highvalue nature of gold ore.

2. PRODUCT OVERVIEW: PRIMARY JAW CRUSHER FOR GOLD ORE PROCESSING

This heavyduty jaw crusher is engineered as the first critical stage in hard rock gold ore comminution. It is designed to accept runofmine (ROM) gold ore with feed sizes up to 1200mm and reduce it to a consistent, manageable product for secondary crushing or SAG mill feed.

Operational Workflow:
1. ROM gold ore is fed via dump truck or loader into the crusher’s vibrating grizzly feeder (VGF), which bypasses fines to optimize capacity.
2. Oversize material enters the crushing chamber where a robust, oscillating jaw exerts immense compressive force against a fixed jaw.
3. The crushed material discharges onto the main product conveyor at a preset closedside setting (CSS), ensuring a predictable product size distribution.

Application Scope & Limitations:
Scope: Ideal for primary crushing of hard rock gold ores (quartz, sulphides), mine waste rock, and aggregate. Suitable for both stationary plant and modular/trackmounted setups.
Limitations: Not designed for wet, sticky ores without prior scalping; requires competent feed control to optimize wear life and capacity.
