1. PAINPOINT DRIVEN OPENING

Are you facing persistent bottlenecks in your gold processing circuit due to unreliable primary crushing? Inconsistent feed size, excessive liner wear, and unplanned maintenance stops directly erode your profit margin. Consider these common operational challenges:
High Downtime Costs: Mechanical failures in the primary stage can halt your entire milling circuit, costing thousands per hour in lost throughput.
Excessive Energy Consumption: Inefficient crushing mechanisms and poorly matched drives lead to disproportionate power use per ton of ore processed.
Premature Wear Part Failure: Abrasive gold ores, particularly those with high quartz content, rapidly degrade crusher liners, increasing part change frequency and labor costs.
Inconsistent Product Size: Poorly controlled discharge settings result in a suboptimal feed for your SAG or ball mill, reducing grinding efficiency and recovery rates.
Regulatory & Site Compliance: Operating noncompliant machinery risks project delays and fines.

Is your current equipment delivering the uptime and costperton metrics required for profitable operation? The solution lies in selecting a robust, engineered primary crusher designed specifically for the demands of gold ore.

2. PRODUCT OVERVIEW

This product line comprises a series of CE Marked jaw crushers engineered as primary gold ore crushing equipment. Designed for the initial size reduction of runofmine (ROM) goldbearing rock, these machines are built for high availability in demanding mineral processing applications.

Operational Workflow:
1. ROM ore is fed into the vibratory grizzly feeder, which bypasses subfines directly to the downstream conveyor.
2. Oversize material enters the deep crushing chamber of the jaw crusher.
3. The aggressive elliptical motion of the swing jaw reduces ore via compressive force.
4. Crushed product discharges onto the main product conveyor at a preset CSS (Closed Side Setting).
5. The system integrates with plant PLCs for automated operation and feed rate control.

Application Scope: Ideal for hard rock gold ores (lode deposits), including sulphidebearing ores. Suitable for stationary plant installation or modular plant frameworks.

Limitations: Not designed as a standalone solution for alluvial/placer deposits requiring scrubbing and screening, or as a tertiary crusher for fine grinding.
