1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inefficient primary crushing? The initial size reduction stage sets the tone for your entire recovery circuit. Common challenges with inadequate Chinese gold ore crushing equipment include:

High Operational Cost: Frequent liner changes and unplanned downtime for maintenance directly increase your cost per ton. A single major component failure can halt production for days.
Inconsistent Feed Size: Poorly calibrated or underpowered crushers produce erratic product sizes, overloading downstream grinding mills and reducing overall recovery efficiency by 515%.
Excessive Energy Consumption: Crushers operating outside their optimal design parameters consume significantly more power, a major fixed cost in mineral processing.
AbrasionRelated Downtime: Gold ores, particularly hard rock deposits with quartz, are highly abrasive. Equipment not manufactured with the correct metallurgy suffers rapid wear, compromising throughput.

Is your primary crusher a bottleneck or a reliable foundation? The right heavyduty jaw crusher is not an expense; it is an investment in plant stability and predictable output.

2. PRODUCT OVERVIEW

Our solution is a series of heavyduty, modular jaw crushers engineered specifically for the primary crushing of hard rock gold ores. This Chinese gold ore crushing equipment is designed for stationary and semimobile plant configurations.

Operational Workflow:
1. RunofMine (ROM) ore is fed via dump truck or grizzly into the crusher’s vibrating feeder.
2. Ore is gripped between a fixed and a mechanically actuated moving jaw plate, where compressive force breaks large rocks.
3. Crushed material discharges through an adjustable gap (closed side setting), determining the final product size for the next stage of processing.

Application Scope: Ideal for primary crushing of goldbearing quartz veins, sulphide ores, and alluvial deposit feed preparation. Capacities range from 50 to over 1,500 tonnes per hour.

Limitations: This equipment is designed for dry or naturally wet ore; it is not suitable for slurry feeding. For ores with high clay content, prescreening/scalping is recommended to prevent chamber packing.

6. APPLICATION SCENARIOS

Hard Rock Underground Mine Portal Application

Challenge A midtier underground gold mine needed to reduce ROM ore (600mm) to 150mm at the portal before conveyor transport to the mill. Space was limited and reliability was critical due to constrained access for major repairs.
Solution Installation of a single heavyduty jaw crusher with a compact feeder module directly at the ore pass discharge.
Results The setup achieved consistent 125mm product at 180 TPH. Availability exceeded 96% over the first year, eliminating truck haulage from the portal and reducing transport costs by an estimated $12/tonne.

Alluvial/Eluvial Deposit Processing Plant

Challenge A West African operation processing weathered oxide ore faced issues with variable clay content causing occasional chamber packing in their old crusher, leading to frequent stoppages.
Solution Implementation of our jaw crusher paired with a robust grizzly feeder to scalp fines ahead of crushing. The deep chamber design provided better handling of sticky feed.
Results Throughput stabilized at design capacity of 220 TPH. Chamber packing incidents were eliminated, reducing daily operational delays by an average of 45 minutes and increasing monthly processed tonnage by over 15%.
