1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable availability eroding your gold processing margins? Managing a gold ore crushing circuit presents distinct challenges that directly impact your bottom line. Common pain points include:
High Abrasion & Maintenance Costs: The extreme hardness and abrasive nature of goldquartz ores rapidly degrade crusher liners, leading to frequent, costly shutdowns for component replacement and excessive spare parts inventory.
Unscheduled Downtime: A primary crusher failure can halt your entire milling operation, costing thousands per hour in lost production and labor inefficiency.
Inefficient Liberation: Inadequate or inconsistent particle size reduction can hinder downstream gold recovery in leaching or gravity circuits, locking value in tailings.
High Energy Consumption: Older or improperly specified crushing equipment can be a significant driver of your plant's power costs per ton processed.
Handling Variable Feed: Fluctuations in ore hardness, moisture, or feed size from the mine can choke or overload a system not designed for such variability.

Is your current crushing solution equipped to minimize these risks while maximizing throughput and recovery? The right professionalgrade equipment is not an expense but a strategic investment in plant stability and profitability.

2. PRODUCT OVERVIEW

Our engineered solution is a range of heavyduty, stationary and modular primary and secondary jaw crushers specifically configured for professional gold ore processing. These units are designed as the foundational stage in a comminution circuit, reliably reducing runofmine (ROM) ore to a consistent size for further grinding.

Operational Workflow:
1. ROM ore is fed via grizzly or apron feeder into the crusher’s robust feed hopper.
2. The highinertia flywheel and optimized kinematics of the crushing chamber facilitate forceful compression of ore between a fixed and a moving jaw plate.
3. Crushed product discharges at the predefined closedside setting (CSS), directly onto a conveyor for transport to the next stage (e.g., cone crusher or SAG mill feed).

Application Scope: Ideal for hard rock gold ores (lode deposits), including quartz veins and mineralized shear zones with unconfined compressive strength (UCS) up to 350 MPa. Suitable for both greenfield installations and retrofit upgrades.

Limitations: Not recommended as a standalone solution for highclay or wet, sticky ores without prior scalping; final product sizing typically ranges from 150mm down to 20mm, requiring secondary/tertiary stages for finer liberation.
