1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable throughput eroding your gold processing margins? Processing gold ore presents distinct challenges that directly impact profitability. Common operational hurdles include:
High Abrasion & Downtime: Quartz and other abrasive minerals in gold ore rapidly wear crusher components, leading to frequent maintenance stops and high parts replacement costs.
Inefficient Liberation: Inadequate primary crushing creates poorly sized feed for milling circuits, hindering optimal gold liberation and recovery rates.
Unscheduled Stoppages: Equipment not engineered for the specific impact and abrasion of hard rock gold deposits fails prematurely, causing costly, unbudgeted downtime.
Energy Intensity: Older crushing stages consume excessive power per ton of ore processed, making energy a dominant and volatile cost factor.
Safety & Reliability Risks: Overreliance on manual intervention for jam clearing or maintenance increases exposure to safety incidents.

Is your current crushing circuit a consistent bottleneck? Are you seeking a reliable private label solution that balances capital efficiency with longterm operating cost control?

2. PRODUCT OVERVIEW

Our Private Label Gold Ore Crushing Equipment is engineered as a robust, highcapacity primary jaw crusher solution designed specifically for the demanding environment of hard rock gold mining. This equipment forms the critical first stage in a comminution circuit, setting the foundation for downstream recovery efficiency.

Operational Workflow:
1. Feed Intake: Runofmine (ROM) gold ore is fed into the vibrating grizzly feeder (optional), which bypasses fines to optimize crusher loading.
2. Primary Reduction: Ore is crushed within a reinforced crushing chamber by a highinertia moving jaw against a fixed jaw.
3. Product Discharge: The crushed product discharges at a preset closedside setting (CSS), ensuring consistent, targetsized output for conveyor transport to secondary crushing or stacking.

Application Scope: Ideal for stationary or semimobile plant installations processing lode or veintype gold ores with high compressive strength and abrasiveness (e.g., quartz, sulphidebearing rock).

Limitations: This primary crusher is not designed as a standalone solution for final product sizing; it requires integration with secondary/tertiary crushing and grinding circuits for optimal liberation. It is also not suited for processing placer/alluvial material without significant feed preparation.

3. CORE FEATURES

HeavyDuty Manganese Steel Jaws | Technical Basis: Isotropic alloy composition with workhardening properties | Operational Benefit: Jaw plates develop a hardened surface layer during operation that extends service life in highly abrasive conditions by up to 40% compared to standard alloys. | ROI Impact: Reduces parts inventory costs and crusher downtime for liner changes, lowering cost per ton crushed.

Hydraulic Adjustment & Clearing | Technical Basis: Integrated dualacting hydraulic cylinders connected to the toggle system | Operational Benefit: Allows operators to adjust the crusher discharge setting quickly and clear blockages remotely from a control panel in under two minutes. | ROI Impact: Eliminates manual, hazardous clearing procedures and maximizes plant uptime by minimizing process interruptions from tramp metal or packing events.

Reinforced HeavyDuty Frame | Technical Basis: Fabricated from highgrade steel plate with stressrelieved welding and oversized bearing housings | Operational Benefit: Provides exceptional structural integrity to withstand continuous highcycle fatigue loads from hard rock crushing. | ROI Impact: Ensures longterm frame alignment and bearing life, protecting your capital investment over a 15+ year service horizon.

Optimized Crushing Chamber Geometry | Technical Basis: Computermodeled nip angle and stroke profile based on gold ore characteristics | Operational Benefit: Promotes aggressive initial reduction and minimizes slabby product, creating more uniform feed size distribution for downstream processes. | ROI Impact: Improves overall circuit throughput stability and supports higher recovery efficiency in milling stages.

Centralized Automated Greasing System | Technical Basis: Programmable lubrication unit with distribution blocks to all key bearings | Operational Benefit: Delivers precise grease volumes at scheduled intervals without operator intervention, even under high dust load conditions. | ROI Impact: Prevents bearing failures—a leading cause of major crusher downtime—and reduces manual maintenance labor requirements.
