1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inefficient primary crushing? Inconsistent feed size, excessive liner wear, and unplanned maintenance are not just operational nuisances—they directly erode profit margins. Consider the tangible costs: every hour of crusher downtime can halt hundreds of tons of highvalue ore processing, while premature component failure leads to recurring capital expenditure and safety risks during changeouts.

Are you currently facing:
Throughput Bottlenecks: Is your primary crusher unable to keep pace with increased mine output or creating a bottleneck for your SAG/Ball mill circuit?
High Cost Per Ton: Are you frequently budgeting for jaw plate or mantle replacements due to abrasive gold ore with high quartz content?
Unscheduled Stoppages: Does bearing failure or tramp metal damage cause catastrophic, unpredictable downtime?
Poor Feed Flexibility: Does your crusher struggle with varying ore hardness or clayrich material, leading to packing and choking?

The right primary gold ore crushing equipment is not a commodity purchase; it is a strategic investment in plant stability and overall recovery efficiency.

2. PRODUCT OVERVIEW: HEAVYDUTY PRIMARY JAW CRUSHER FOR GOLD ORE

This product line comprises a range of robust, stationary and modular primary jaw crushers engineered specifically for the rigorous demands of runofmine (ROM) gold ore processing. These machines serve as the first critical stage in comminution, reducing large, blasted ore to a consistent, manageable size for downstream milling.

Operational Workflow:
1. ROM gold ore (up to 80% of crusher feed opening) is delivered via haul truck or loader into the vibrating grizzly feeder (VGF).
2. The VGF removes fines and bypasses subsize material, while directing oversize rock into the crushing chamber.
3. A highinertia flywheel drives an eccentrically moving jaw, applying compressive force against a fixed jaw to fracture the ore.
4. Crushed product discharges onto the main conveyor at a preset closedside setting (CSS), typically between 125mm to 200mm for primary crushing.

Application Scope & Limitations:
Scope: Ideal for hardrock gold deposits (lode ore) such as quartz veins and sulphideassociated ores. Suited for both greenfield installations and retrofit upgrades in CIP/CIL processing plants.
Limitations: Not designed as a standalone solution for alluvial/placer deposits requiring scrubbing and screening. Maximum feed size is determined by model selection; extremely sticky, highclay ores may require preprocessing or specific chamber design modifications.

3. CORE FEATURES
