1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable throughput constraining your gold processing plant’s profitability? The primary crushing stage for gold ore presents distinct challenges that directly impact your entire recovery circuit. Common pain points include:

Excessive Downtime for Maintenance: Frequent liner changes and unplanned repairs on abrasive, highsilica gold ores halt your milling circuit, costing thousands per hour in lost production.
Inconsistent Feed Size Reduction: Poorly controlled product size from primary crushing creates bottlenecks in SAG or ball mill feed, reducing grinding efficiency and increasing specific energy consumption (kWh/t).
High Operational Costs: Premature wear on crusher components due to extreme abrasion leads to unsustainable spending on manganese steel castings and associated labor.
Material Handling Issues: Inefficient crushing can produce excessive fines prematurely or fail to break apart hard, competent vein material, causing chute blockages and conveyor spillage.

Is your current primary crushing solution robust enough to handle variable ore hardness while maintaining availability above 95%? Can you reduce your cost per ton in the first critical stage of size reduction?

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This product line comprises a series of robust, highcapacity jaw crushers engineered specifically for the rigorous demands of primary gold ore crushing. Designed to accept runofmine (ROM) feed directly from the mine, this equipment serves as the foundational workhorse of your comminution circuit.

Operational Workflow:
1. ROM ore (up to 1200mm) is fed into the vibrating grizzly feeder (VGF), which scalps out fine material and directs oversize to the crusher.
2. Ore enters the deep crushing chamber of the jaw crusher, where a highstrength, oscillating jaw exerts immense compressive force against a fixed jaw.
3. The ore is fractured along natural cleavage planes, reduced to a predetermined product size (typically 150250mm).
4. Crushed material discharges onto a main conveyor for transport to secondary crushing or stockpiling.

Application Scope & Limitations:
Scope: Ideal for primary crushing of hard, abrasive gold ores (quartz, sulphides), moderate clay content materials, and runofmine feed in both stationary plant and semimobile configurations.
Limitations: Not designed as a standalone solution for highclay or wet, sticky ores without prescreening; final product size is less uniform compared to cone crushers in closedcircuit secondary/tertiary roles.

3. CORE FEATURES

6. APPLICATION SCENARIOS

Hard Rock Underground Mine Expansion

Challenge: An existing underground operation expanding throughput faced bottlenecks with an aging primary crusher struggling with competent quartz vein ore, causing weekly unplanned stoppages.
Solution: Installation of a heavyduty gold ore jaw crusher in a new surface primary crushing station fed via skip.
Results: Achieved sustained availability of 96.5%. Liner life extended from 8 weeks to an average of 12 weeks, contributing to a documented 18% reduction in primary crushing OPEX per tonne.

Alluvial/Transitional Ore Processing Plant

Challenge: A plant processing transitional ore (mix of oxide and fresh sulphide material) experienced severe wear variability and plugging issues with their previous crusher during wet seasons.
Solution: Implementation of our jaw crusher with a deep chamber design and enhanced discharge clearance paired with a heavyduty apron feeder for sticky feed conditions.
Results: Eliminated seasonal plugging events entirely. Achieved consistent product sizing yearround (+/15mm variance), optimizing secondary cone crusher performance.
