1. PAINPOINT DRIVEN OPENING

Are your gold ore processing operations constrained by unreliable primary crushing? Inconsistent feed size, excessive liner wear, and unplanned maintenance directly impact your mill throughput and recovery rates. Consider these common challenges:
Unscheduled Downtime: Catastrophic failure of a critical crusher component can halt your entire processing line for days, costing thousands per hour in lost production.
High Operating Costs: Premature wear on manganese liners and frequent part replacements under abrasive gold ore conditions create a significant and recurring expense.
Bottlenecked Throughput: An undersized or inefficient primary crusher limits feed to your SAG/Ball mill circuit, capping your plant’s overall gold production capacity.
Product Inconsistency: Poorly controlled discharge sizing leads to inefficiencies downstream, affecting grinding circuit performance and ultimately, recovery.

Is your current gold ore crushing equipment a source of cost and complexity rather than a foundation for reliability? The solution requires machinery engineered not just to crush, but to endure.

2. PRODUCT OVERVIEW

Our OEM factory specializes in the design and manufacture of heavyduty primary jaw crushers specifically configured for gold ore crushing applications. This equipment serves as the first critical stage in mineral liberation, reducing runofmine (ROM) ore to a consistent, manageable size for secondary processing.

Operational Workflow:
1. ROM gold ore is fed into the vibrating grizzly feeder (optional), which bypasses subsize material and directs oversize to the crusher.
2. Ore enters the robust crushing chamber of the jaw crusher, where a highpressure mechanical force is applied between a fixed and a moving jaw plate.
3. The compressive action breaks the ore along natural fissures and weaknesses.
4. Crushed material discharges through an adjustable gap at the bottom, determining the final product size.
5. The crushed product is conveyed to the next stage of your beneficiation circuit.

Application Scope & Limitations:
Scope: Ideal for primary crushing of hard and abrasive gold ores (quartz, sulphides), including runofmine material with large feed sizes. Suited for both stationary plant installations and modular plant designs.
Limitations: Not designed as a fine reduction or grinding machine. Maximum feed size is constrained by the specific model’s inlet dimensions. Performance is optimal with proper feed control to prevent choking.

6. APPLICATION SCENARIOS

Hard Rock Gold Mine – West Africa

Challenge: A major operation faced excessive downtime every 810 weeks due to rapid liner wear in their primary jaw crusher processing highly abrasive quartz vein ore. This created a persistent bottleneck.
Solution: Implementation of our specifically configured jaw crusher with workhardening liner alloy and optimized chamber geometry.
Results: Liner life extended to an average of 1416 weeks. Combined with hydraulic adjustment, this change contributed to an estimated 17% increase in annual crusher availability, directly supporting higher mill feed rates.
