1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inefficient primary crushing? The initial reduction stage sets the tone for your entire recovery circuit. Common challenges with suboptimal ODM gold ore crushing equipment include:
High Operational Cost: Excessive energy consumption from oversized or underperforming crushers, coupled with the high cost of premature wear part replacement in abrasive gold ores.
Unplanned Downtime: Frequent mechanical failures and lengthy maintenance windows that halt your milling circuit, costing thousands per hour in lost production.
Inconsistent Feed Size: Poorly calibrated or worn crushing chambers produce erratic feed for your SAG/Ball mills, reducing grinding efficiency and increasing specific energy consumption.
Low Recovery Risk: Inadequate liberation due to poorly sized crush product can lock fine gold within larger particles, negatively impacting downstream cyanidation or gravity recovery rates.

Is your crushing circuit a cost center plagued by stoppages, or a reliable, efficient foundation for maximum gold yield?

2. PRODUCT OVERVIEW

Our solution is a range of heavyduty, ODMengineered primary jaw crushers and gyratory crushers specifically configured for gold ore processing. This equipment is designed as the first critical stage in comminution, handling runofmine (ROM) material to produce a consistent, optimally sized feed for secondary crushing or direct mill feed.

Operational Workflow:
1. ROM ore is fed into the robust vibrating grizzly feeder (optional), which bypasses fines to reduce crusher load.
2. Oversize material enters the crusher’s chamber, where immense mechanical force is applied via a fixed jaw and an eccentric moving jaw (or mantle).
3. The compressive crushing action breaks the ore along natural fracture lines.
4. The crushed product discharges onto a main conveyor at a predetermined closedside setting (CSS), ensuring granulometry control.
5. The system operates in sync with downstream processes via PLCcontrolled variable speed drives for optimal flow.

Application Scope: Ideal for hard rock gold ores (quartz, sulphidebearing), alluvial deposit processing plants, and heap leach operations requiring precise crush size. Limitations: Not designed as a standalone solution for full comminution; requires integration with secondary/tertiary crushing or milling circuits for final liberation.

3. CORE FEATURES

6. APPLICATION SCENARIOS

Hard Rock Underground Mine Expansion

Challenge: An existing operation needed to double primary crush capacity without expanding the footprint of the surface plant. The existing crusher caused frequent bottlenecks.
Solution: Implementation of a highcapacity ODM gyratory crusher with a steep chamber design tailored for the mine’s specific quartzgold ore body.
Results: Achieved a 95% throughput increase within the same footprint. Consistent product size improved SAG mill feed stability, yielding an overall circuit energy saving of 8%.

Alluvial/Heap Leach Operation

Challenge: A heap leach project faced high operating costs due to rapid wear on crusher liners from extremely abrasive material, requiring biweekly shutdowns.
Solution: Installation of an ODM jaw crusher equipped with proprietary abrasionresistant liners and an automated greasing system.
Results:Liner life extended from 14 to 38 days. Combined with reduced manual maintenance, this change increased annual operational availability by approximately 400 hours.

7. COMMERCIAL CONSIDERATIONS

Our ODM gold ore crushing equipment is offered in three primary tiers:
1. Standard Duty Configuration: Core reliability features for moderateabrasion ores and continuous operation.
2. Heavy Duty Configuration: Includes all premium abrasionresistant liners, enhanced condition monitoring packages, and heavyduty bearings for severe service applications.
