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: Undersized crushers choke your SAG mill, limiting overall plant capacity.
High Maintenance Costs: Frequent jaw plate or mantle changes halt production for hours, with replacement part expenses eroding margins.
Poor Liberation Characteristics: Incorrectly sized ore reduces grinding circuit efficiency and can negatively affect downstream cyanidation or gravity recovery rates.

Is your primary crushing station the weakest link in your profit chain? The solution begins with selecting the right heavyduty equipment engineered for the specific abrasiveness and variability of gold ore.

2. PRODUCT OVERVIEW: HEAVYDUTY JAW CRUSHER FOR GOLD ORE PRIMARY REDUCTION

This product line encompasses a range of robust, highcapacity jaw crushers designed specifically for the primary crushing stage of gold ore processing. The operational workflow is engineered for reliability:
1. Feed Intake: Runofmine (ROM) ore is delivered via haul truck or loader into a vibrating grizzly feeder (optional), which removes fines and bypasses undersize material.
2. Primary Reduction: Ore is crushed between a fixed and a reciprocating manganese steel jaw plate, applying compressive force to reduce material to a targeted top size.
3. Discharge: Crushed product is discharged onto the main conveyor system for transport to secondary crushing or directly to the grinding circuit.

Application Scope: Ideal for hard rock gold ores (quartz, sulphidebearing), providing the first critical size reduction. Limitations: Not designed as a standalone solution; requires integration with feeding and conveying systems and is typically followed by secondary/tertiary crushing for mill feed preparation.

6. APPLICATION SCENARIOS

Hard Rock Underground Mine RampUp

Challenge: A new underground operation needed to double its primary crushing capacity within an existing building footprint to meet expanded mill feed requirements.
Solution: Implementation of a single, largercapacity jaw crusher with a compact but heavier design replaced two older units.
Results: Achieved a 110% increase in hourly throughput within the same footprint. Reduced planned maintenance events from two schedules to one.

Alluvial/Heap Leach Operation

Challenge: A highclay content oxide ore was causing frequent plugging in the previous grizzly and crusher chamber, resulting in daily downtime for cleaning.
Solution: Installation was paired with a heavyduty vibrating grizzly feeder featuring highG force drives and a customized jaw crusher chamber profile.
Results: Plugging events reduced by over 90%. Overall plant availability increased by an average of two hours per week.
