1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inconsistent feed size, excessive liner wear costs, and unplanned maintenance halting your production line? Inefficient primary crushing directly impacts your entire recovery circuit, leading to:
Throughput Bottlenecks: Undersized or oversized crusher output reduces grinding circuit efficiency and overall plant capacity.
Spiraling Maintenance Costs: Frequent jaw liner or mantle replacements on abrasive gold ores create significant parts expenditure and labor downtime.
High Energy Consumption: Crushers operating outside their optimal design parameters consume excess power per ton of ore processed.
Safety & Downtime Risks: Manual clearing of bridging events exposes personnel to risk and stops revenue generation.

Is your current primary crushing solution truly optimized for the variable hardness and abrasiveness of your gold ore body? What would a 1520% improvement in operational uptime mean for your annual yield?

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This product line comprises a series of robust, highcapacity jaw crushers engineered specifically for the primary crushing stage of hardrock gold ore processing. The operational workflow is designed for reliability:
1. Feed Intake: RunofMine (ROM) ore is delivered via dump truck or loader into the vibrating grizzly feeder (VGF), which scalps out fine material.
2. Primary Reduction: Oversize material is directed into the crusher’s chamber, where a highinertia flywheel and optimized kinematics facilitate forceful compression between the fixed and moving jaw plates.
3. Discharge & Conveyance: Crushed product exits at the preset closedside setting (CSS) and is conveyed to the next stage of your mineral processing plant.

Application Scope: Ideal for primary reduction of quartz veinhosted, sulphidebearing, and other hardrock gold ores with compressive strengths up to 320 MPa. Limitations: Not designed for wet, sticky ores without prior screening/scalping; requires a prepared foundation and appropriate feed system integration.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer crushing stroke | Operational Benefit: Enables higher throughput capacity and effective reduction of larger feed block sizes common in gold mining. | ROI Impact: Maximizes use of loading equipment cycles, improving tonsperhour (TPH) metrics from the first stage.

HeavyDuty Manganese Steel Jaw Plates | Technical Basis: Workhardening austenitic manganese steel with proprietary alloy mix. | Operational Benefit: Liners develop a hard, wearresistant surface layer upon impact with abrasive gold ore, extending service life by up to 30% over standard grades. | ROI Impact: Reduces liner changeout frequency, lowering parts inventory costs and associated maintenance labor hours.

Hydraulic Adjustment & Clearing System | Technical Basis: Integrated hydraulic cylinders for CSS adjustment and chamber clearing (tramp release). | Operational Benefit: Operators can adjust product size or clear a stall in minutes from a remote location without manual intervention inside the crusher. | ROI Impact: Minimizes unplanned downtime due to bridging or uncrushable material; enhances personnel safety by removing them from hazardous areas.

Robust Eccentric Shaft & Bearing Assembly | Technical Basis: Forged from highgrade steel and supported by oversized spherical roller bearings. | Operational Benefit: Provides exceptional durability under continuous highload conditions, ensuring stable operation and longterm mechanical integrity. | ROI Impact: Protects against catastrophic bearing failure—a major cause of extended shutdowns—delivering predictable operational life.

Modular Frame Design & Corrosion Protection | Technical Basis: Fabricated steel sections with specialized internal ribbing; multistage protective paint system. | Operational Benefit: Simplifies transport to remote sites; offers superior resistance to dust ingress and environmental corrosion in harsh mining conditions. | ROI Impact: Reduces longterm structural maintenance needs and protects asset resale value.
