1. PAINPOINT DRIVEN OPENING

Are you managing gold ore processing operations burdened by inconsistent throughput, escalating maintenance costs, and unpredictable equipment performance? The primary crushing stage sets the tone for your entire recovery circuit. Inefficient or unreliable gold ore crushing equipment directly translates to:
Bottlenecks & Downtime: Unplanned stoppages for liner changes or mechanical failures halt your milling circuit, costing thousands per hour in lost production.
High Operational Costs: Excessive energy consumption per ton crushed, combined with frequent wear part replacement, erodes profit margins.
Poor Liberation & Recovery: Inconsistent product size distribution from the primary crusher can compromise downstream grinding and leaching efficiency, leaving valuable gold locked in larger particles.
Safety & Operational Complexity: Manual clearing of bridging events or arduous maintenance procedures increase risk and labor requirements.

Is your current setup delivering the optimal balance of availability, costperton, and product quality necessary for profitable gold recovery? The right OEM contract manufacturing partnership addresses these exact challenges.

2. PRODUCT OVERVIEW

Our service provides engineeredtoorder primary and secondary gold ore crushing equipment, manufactured under contract to your precise specifications. We specialize in robust jaw crushers, gyratory crushers, and cone crushers built for the abrasive and often highclay content of gold ores.

Operational Workflow:
1. Feed Acceptance: Engineered hopper and feeder design ensures consistent material flow to the crusher, mitigating segregation and bridging.
2. Comminution: Applicationspecific chamber geometry and kinematics apply optimal compressive or impact force to fracture the ore.
3. Product Control: Adjustable crusher settings (e.g., CSS) govern the topsize of the output product for consistent feed to the SAG/Ball mill or heap leach pad.
4. Discharge & Conveyance: Designed discharge trajectories integrate smoothly with existing conveyor systems to minimize spillage and dust.

Application Scope: Suited for hard rock lode gold deposits (quartz veins), oxidized ores, and transitional materials. Ideal for greenfield projects or retrofitting aging circuits.
Limitations: Not a substitute for grinding; final product size is typically >10mm (for primary) or >20mm (for secondary). Specific designs are required for fully autogenous grinding (AG) circuits without secondary crushing.
