Targeted Solutions for Gold Ore Crushing: Maximize Recovery, Minimize Downtime

Are you facing persistent bottlenecks in your gold processing circuit that erode profitability? The primary crushing stage sets the tone for your entire recovery operation. Common challenges include:
High Abrasion Costs: Quartz and other hard gangue minerals rapidly wear crusher components, leading to frequent liner changes, excessive maintenance labor, and soaring spare parts inventories.
Unscheduled Downtime: Equipment failure at the primary stage halts the entire milling circuit. Every hour of lost production can represent tens of thousands in unrealized gold yield.
Inefficient Liberation: Inconsistent feed size from poor crushing creates a bottleneck for grinding mills, reducing throughput and increasing specific energy consumption per ton.
High Energy Intensity: Older crushing technology often operates at fixed, inefficient rates, drawing maximum power regardless of feed conditions or required product size.

How do you select a gold ore crushing equipment solution that directly addresses these operational costs while safeguarding your plant’s availability and recovery metrics?

Product Overview: HeavyDuty Primary Jaw Crusher for Gold Ore Processing

Our engineered gold ore crushing equipment is built around a robust, singletoggle jaw crusher design optimized for highabrasion gold ore applications. The operational workflow is streamlined for reliability:
1. Feed & PreScreening: RunofMine (ROM) ore is directed to a grizzly feeder, removing fines to bypass the crusher and reduce wear.
2. Primary Reduction: The core jaw crusher utilizes a highstrength manganese steel jaw plate to apply compressive force, breaking large ore pieces (up to 1200mm) into a consistent, manageable size.
3. Discharge & Conveyance: Crushed product is discharged onto a conveyor system at a controlled rate for transport to secondary crushing or stockpiling.

Application Scope: Ideal for stationary or semimobile primary crushing stations processing hard rock gold ores with high silica content (e.g., quartz veins). Limitations: Not designed as a standalone solution for complete comminution; requires integration with secondary/tertiary crushing and grinding circuits for full liberation.

Core Features: Engineered for Durability and Control

Our gold ore crushing equipment incorporates features designed with plant managers' key priorities in mind.

Asymmetric Jaw Design | Technical Basis: Optimized kinematics & higher stroke at the feed opening | Operational Benefit: Increases capacity by up to 15% versus traditional designs and actively draws material into the crushing chamber, reducing bridging. | ROI Impact: Higher throughput per capital dollar invested and less operator intervention required.
Hydraulic Toggle System | Technical Basis: Replaces traditional mechanical toggle plates with a hydraulic cylinder | Operational Benefit: Provides automatic tramp iron release and clearing of stalled chambers in under two minutes without manual disassembly. Allows quick adjustment of the closedside setting (CSS) for product size control. | ROI Impact: Prevents catastrophic damage from uncrushables, drastically reducing risk of major repair costs and associated production losses.
Modular Liner Assembly | Technical Basis: Segmented, reversible jaw plates secured with wedgelock systems | Operational Benefit: Reduces liner changeout time by up to 50%. Reversible design doubles liner life by allowing rotation of highwear sections. | ROI Impact: Lowers maintenance labor costs and increases crusher availability by minimizing downtime for wear part replacement.
PLCAutomated Drive & Control | Technical Basis: Variable Frequency Drive (VFD) coupled with programmable logic controllers | Operational Benefit: Enables soft starts to reduce mechanical stress and allows operators to finetune crusher speed and performance based on realtime feed conditions. | ROI Impact: Reduces peak power demand (lowering utility costs) and optimizes energy use per ton crushed.
Reinforced Frame & Pitman Assembly | Technical Basis: Finite Element Analysis (FEA)designed cast steel or fabricated frame with oversized bearings | Operational Benefit: Provides exceptional structural integrity to withstand continuous highcycle loading from hard rock ores. Minimizes stress fractures and bearing failures. | ROI Impact: Extends major component service life, protecting your longterm capital asset.

Application Scenarios

Hard Rock Underground Mine Expansion

Challenge: An existing underground operation expanding its mill throughput was constrained by an aging primary crusher causing weekly unplanned stoppages and inconsistent feed to the SAG mill.
Solution: Installation of our heavyduty jaw crusher as the new primary station, integrated with an automated rock breaker system at the dump pocket.
Results: Primary circuit availability increased from 82% to 96%. Consistent crusher product size contributed to a measured 5% increase in SAG mill throughput due to improved grindability.

Alluvial/Heap Leach Operation Upgrading

Challenge: A heap leach operation processing transitional oxide/sulfide ore experienced excessive wear costs from using a standard impactor not suited for increasingly abrasive deeperlevel ore.
Solution: Replacement with our purposebuilt gold ore jaw crusher featuring modular liners and hydraulic toggle adjustment.
Results: Liner replacement frequency decreased from every 8 weeks to every 14 weeks. The ability to quickly adjust CSS allowed optimization of crush size for optimal agglomeration and leach kinetics.
