1. PAINPOINT DRIVEN OPENING

Are you facing persistent bottlenecks in your primary crushing circuit that limit overall plant throughput? The first reduction of gold ore is a critical, highstress operation where equipment failure carries severe consequences. Common challenges include:

Unplanned Downtime: Catastrophic failures of wear components or the main shaft in your primary crusher can halt processing for 2472 hours, costing thousands per hour in lost production.
High Maintenance Costs: Frequent replacement of liners, bearings, and other wear parts due to abrasive gold ores and tramp metal incidents creates recurring expense and labor burdens.
Inconsistent Feed Size Reduction: Inefficient crushing leads to poor fragmentation, increasing load on downstream grinding circuits and raising energy consumption per ton.
Safety & Operational Risks: Manual clearing of blockages or dealing with dust emissions exposes personnel to hazardous situations.

Is your current gold ore crushing equipment a reliable asset or a recurring liability? The solution lies not just in a stronger machine, but in a smarter system designed for the specific demands of auriferous ore processing.

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This product line encompasses a series of robust, stationary and modular jaw crushers engineered specifically for the primary crushing of runofmine (ROM) gold ore. Designed to handle abrasive quartzite, sulphide ores, and weathered material with high compressive strength.

Operational Workflow:
1. ROM ore is fed via dump truck or loader into the vibrating grizzly feeder (optional), which scalps out fine material to reduce crusher load.
2. Oversize material enters the crusher’s chamber, where a highinertia flywheel and optimized kinematics ensure consistent nip angle and powerful crushing strokes.
3. Crushed product discharges onto the main conveyor at a preset closedside setting (CSS), achieving targeted fragmentation for optimal SAG or ball mill feed.

Application Scope: Primary crushing application for hard rock gold mining operations processing 502,000+ TPD. Suitable for both greenfield installations and retrofit upgrades.
Limitations: Not designed for wet, sticky ores without proper feed system modifications; maximum feed size is modeldependent as per specifications below.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Increased nip angle and longer fixed jaw die length. | Operational Benefit: Enables higher capacity and reduces bridging; produces a consistent, wellgraded product curve. | ROI Impact: Improves downstream mill throughput by up to 8% through optimized feed size distribution.

HeavyDuty Frame & Rotational Dynamics | Technical Basis: Finite Element Analysis (FEA)designed stressrelieved steel frame paired with largediameter forged eccentric shaft. | Operational Benefit: Withstands shock loads from uncrushables; minimizes frame fatigue and risk of catastrophic failure. | ROI Impact: Extends operational lifespan by years, protecting capital investment.

QuickChange Wedge System for Jaw Dies | Technical Basis: Hydraulically assisted toggle tensioning and wedge lock system replaces outdated manual shim adjustment. | Operational Benefit: Reduces jaw die replacement downtime from hours to under 90 minutes. Your maintenance crew faces less risk and exertion. | ROI Impact: Increases annual available operating hours, directly boosting production capacity.

Integrated Dust Suppression & Sealing | Technical Basis: Positivepressure labyrinth seals at bearing housings and multiple spray nozzle ports at feed/discharge points. | Operational Benefit: Protects critical bearings from abrasive dust; controls airborne particulates at transfer points for improved site compliance and operator health. | ROI Impact: Reduces premature bearing failures by over 60%, lowering parts inventory costs.

PLCBased Automation & Monitoring Interface | Technical Basis: Standard integration with plant SCADA via Modbus; monitors power draw, hydraulic pressure, bearing temperature, and CSS setting. | Operational Benefit: Provides realtime operational data and predictive maintenance alerts; allows remote adjustment of settings for different ore types. | ROI Impact: Prevents unplanned stops through condition monitoring; optimizes performance per ore blend.

6. APPLICATION SCENARIOS

Hard Rock Underground Mine Expansion

Challenge: An existing underground operation expanding its surface primary crush plant needed a compact yet highcapacity crusher to handle variable quartz vein ore without causing vibration issues on the new elevated structure.
Solution: Installation of our modular JC100 heavyduty gold ore jaw crusher with an integrated base frame and vibration isolation pads.
Results: Achieved design capacity of 450 TPH within one week of commissioning; structural vibration readings remained within safe limits (<12 mm/s). Plant availability reached 96% in the first quarter.

Alluvial/Heap Leach Operation Upgrade

Challenge: A heap leach operation using older equipment suffered from excessive downtime due to liner changes and inconsistent product size affecting agglomeration efficiency.
Solution: Retrofit replacement with our gold ore jaw crusher featuring the quickchange wedge system.
Results:Liner changeout time reduced by approximately65%. The improved product gradation led to more uniform agglomeration binder distribution,saving an estimated15% on reagent costs while improving permeability.
