1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable throughput crippling your gold processing plant’s profitability? The primary crushing stage for gold ore is a critical bottleneck where inefficiencies cascade, eroding margins. Common challenges include:
Excessive Downtime: Frequent liner changes and unplanned maintenance on abrasive, hard rock gold ore halt your entire processing line.
High Energy Consumption: Inefficient crushing action directly translates to unsustainable power costs per ton of ore processed.
Poor Fines Control & Gold Loss: Overcrushing can create slimes that are difficult to recover in downstream leaching or gravity circuits, potentially locking away valuable metal.
Inconsistent Feed Handling: Fluctuating ore sizes and moisture content from the mine face lead to chokefeeding, surging, and reduced equipment lifespan.

Is your current primary crusher a source of constant cost and reliability concerns? The solution requires equipment engineered not just for force, but for the specific abrasion and variability of goldbearing rock.

2. PRODUCT OVERVIEW: HEAVYDUTY GOLD ORE JAW CRUSHER

This heavyduty, stationary jaw crusher is engineered as the first stage of comminution for runofmine (ROM) gold ore. It is designed to reliably reduce large, abrasive feed material to a consistent product size for efficient secondary crushing and milling.

Operational Workflow:
1. ROM gold ore (up to 1200mm) is fed via dump truck or grizzly into the crusher’s vibrating grizzly feeder (VGF).
2. The VGF removes fines and directs oversize material into the deep crushing chamber, where a robust moving jaw exerts immense compressive force against a fixed jaw.
3. Crushed ore discharges through an adjustable gap (closed side setting), determining final product size for the next stage of your gold recovery circuit.

Application Scope & Limitations:
Scope: Ideal for primary crushing of hard rock gold ores (quartz, sulphides), moderate clay content materials, and mine waste rock. Suitable for both greenfield installations and retrofit replacements.
Limitations: Not designed as a standalone solution for highclay or wet, sticky ores without prescreening; final product size is typically not fine enough for direct leaching without secondary/tertiary stages.
