1. PAINPOINT DRIVEN OPENING

Are your gold processing operations hampered by inconsistent feed material, excessive downtime, and spiraling maintenance costs? The primary crushing stage sets the tone for your entire recovery circuit. Inefficient or unreliable CE Marked gold ore crushing equipment directly impacts mill throughput, energy consumption, and ultimately, your bottom line.

Consider these common challenges:
Unplanned Downtime: Frequent mechanical failures in harsh, abrasive environments lead to production halts, costing thousands per hour in lost recovery.
High Wear Part Costs: Standard crusher liners and components degrade rapidly under the stress of hard, often quartzrich gold ore, requiring expensive and frequent replacement.
Inconsistent Product Size: Poorly controlled output size distribution creates bottlenecks in downstream processes like milling and leaching, reducing overall plant efficiency by 1525%.
Safety & Compliance Risks: Equipment not engineered to stringent EU safety directives poses operational hazards and can restrict your ability to work on international projects.

Is your current crushing solution equipped to handle variable ore hardness while maximizing uptime and protecting your operational budget? The right foundation begins with purposeengineered primary reduction.

2. PRODUCT OVERVIEW

This product line encompasses a range of robust, stationary and modular primary jaw crushers specifically engineered for the initial size reduction of runofmine (ROM) gold ore. Designed for high availability in demanding mineral processing applications, this equipment forms the critical first link in the comminution chain.

Operational Workflow:
1. ROM gold ore is fed via dump truck or loader into a vibrating grizzly feeder (optional), which scalps out fine material.
2. Oversize material is directed into the crusher’s chamber, where a highinertia flywheel and optimized kinematics facilitate powerful compressive crushing.
3. The crushed product is discharged onto a main conveyor at a consistent, adjustable size ready for secondary crushing or direct feed to a SAG/ball mill circuit.

Application Scope: Ideal for hard rock gold deposits (lode ore), such as those containing quartz veins. Suited for medium to hightonnage fixed plant installations or modular mining setups.

Limitations: Not designed as a standalone solution for alluvial or placer deposit processing where scrubbing and screening are primary functions. Maximum feed size and capacity are defined by model selection.
