1. PAINPOINT DRIVEN OPENING

Are your gold processing operations constrained by inefficient primary size reduction? The initial crushing stage sets the tone for your entire recovery circuit. Common challenges with suboptimal gold ore crushing equipment include:
High Operational Cost: Premature wear on manganese jaws and liners from abrasive quartz and sulfide ores leads to frequent, costly replacements and excessive downtime.
Inconsistent Feed Size: Poorly sized output creates bottlenecks in downstream processes like SAG mills or leaching heaps, reducing overall plant throughput and recovery rates.
Unplanned Downtime: Mechanical failures in critical components under hightension loads halt production, directly impacting tonnage processed and revenue.
Safety & Maintenance Hazards: Complex adjustment mechanisms and manual clearing of bridged material increase risk for maintenance crews.

Is your operation achieving maximum yield per ton of ore processed? Are you managing maintenance costs effectively without sacrificing availability? The solution begins with selecting the right primary crusher engineered specifically for the demands of gold ore.

2. PRODUCT OVERVIEW: GOLD ORE JAW CRUSHER

This product is a heavyduty, robustly constructed jaw crusher designed as the primary workhorse for hard rock gold ore processing plants. It is engineered to accept runofmine (ROM) feed directly from the mine, delivering a consistent, coarse product suitable for secondary crushing or direct feed to a milling circuit.

Operational Workflow:
1. ROM gold ore is fed into the vibrating grizzly feeder (optional), which bypasses fines to optimize crusher chamber loading.
2. Oversize material enters the deep crushing chamber where a powerful elliptical motion applies compressive force against a fixed jaw plate.
3. The crushed product discharges at the bottom outlet, with size determined by the hydraulically adjustable closedside setting (CSS).
4. Crushed material is conveyed to the next stage in your beneficiation process.

Application Scope: Ideal for primary crushing of hard, abrasive gold ores (quartz, sulphidebearing). Suitable for both stationary plant installations and modular/trackmounted setups.
Limitations: Not designed for wet, sticky ores without prior scalping; maximum feed size is constrained by crusher model dimensions.

6. APPLICATION SCENARIOS

Hard Rock Underground Mine Expansion

Challenge: An existing underground operation needed to increase mill feed capacity by 30%. The existing primary crusher was a bottleneck with frequent liner wear issues on their highsilica ore.
Solution: Installation of a highcapacity jaw crusher model focused on abrasion resistance and rapid CSS adjustment capabilities.
Results: Achieved a 35% increase in primary circuit throughput while extending jaw die replacement intervals from every 8 weeks to every 12 weeks under similar conditions.

Alluvial/Vein Processing Plant Retrofit

Challenge:A plant processing mixed freemilling and sulfide vein material experienced high downtime due to tramp metal entering the crusher with feed from smallscale contractors.
Solution:The existing primary crusher was replaced with a unit featuring an integrated hydraulic toggle system for automatic overload protection.
Results:Eliminated shaft breakage incidents. Uncrushable material release events now cause less than 30 minutes of stoppage versus an average of 4 hours previously for inspection/clearance.
