1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent feed size, excessive liner wear costs, and unplanned downtime? Inefficient primary crushing directly impacts your entire recovery circuit, leading to:
Throughput Bottlenecks: Mismatched crusher output can choke downstream milling processes, limiting plant capacity.
High Maintenance Costs: Frequent jaw liner replacements and component failures due to abrasive gold ore create significant operational expenditure and labor hours.
Unpredictable Availability: Mechanical failures in the primary stage halt all processing, costing thousands per hour in lost production.

Is your primary crushing station a reliable asset or a recurring source of cost and delay? The solution begins with selecting equipment engineered specifically for the demanding nature of gold ore.

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This heavyduty jaw crusher is engineered as the primary crushing solution for runofmine (ROM) gold ore. It is designed to accept large, irregular feed material and reduce it to a consistent, manageable size for secondary crushing or direct feed to a SAG/Ball mill circuit.

Operational Workflow:
1. ROM gold ore is fed into the vibrating grizzly feeder (optional), which bypasses subsize material.
2. Oversize material enters the crusher’s robust chamber, where a highinertia flywheel and large eccentric shaft drive a powerful crushing motion.
3. The compressive force between the fixed and moving jaw plates fractures the ore along its natural cleavage planes.
4. Crushed product discharges at the predefined closedside setting (CSS), determining final product size.

Application Scope: Ideal for hard rock gold ores (quartz, sulphides), moderate abrasion applications. Best suited for stationary or semimobile primary crushing stations.
Limitations: Not recommended for highly claybound or wet, sticky ores without prior scalping; requires a prepared foundation and feed system.
