1. PAINPOINT DRIVEN OPENING

Are you managing gold ore processing operations burdened by inconsistent feed material, escalating energy costs, and unplanned maintenance halting your production line? The primary crushing stage sets the tone for your entire recovery circuit. Inefficient or unreliable OEM gold ore crushing equipment directly impacts throughput, increases wear part consumption, and creates bottlenecks that affect downstream milling and leaching efficiency.

Consider these operational challenges:
High Downtime Costs: Unplanned failures in critical crusher components can cost thousands per hour in lost production and labor.
Suboptimal Liberation: Inconsistent particle size distribution from the primary stage reduces overall gold recovery rates in subsequent processes.
Excessive Energy Consumption: Older or poorly matched crushing equipment operates inefficiently, making power costs a significant and growing operational expense.
High Maintenance Complexity: Equipment that requires frequent, specialized service or hardtosource parts increases your total cost of ownership and operational risk.

Is your current crushing solution delivering the reliability, efficiency, and costpertonne needed to maximize the value of your ore body?

2. PRODUCT OVERVIEW

Our solution is engineered OEM gold ore crushing equipment, specifically primary jaw crushers and gyratory crushers designed for highcapacity, abrasive gold ore applications. This equipment forms the robust foundation of your mineral processing plant, accepting runofmine (ROM) feed and delivering a consistent, coarse product for secondary crushing or direct feed to a SAG mill.

Operational Workflow:
1. ROM ore is fed into the crusher’s large receiving hopper via haul truck or loader.
2. The fixed jaw and moving jaw (or mantle in gyratory models) create a compressive force, breaking the ore against itself.
3. Crushed material exits through the discharge opening (gap), with size controlled by the closedside setting (CSS).
4. The product is conveyed to the next stage of your process circuit.

Application Scope: Ideal for hightonnage hard rock gold mining operations (lode deposits). Suitable for feed sizes up to 1200mm, producing product sizes typically between 150mm to 250mm.

Limitations: Not designed for wet, sticky ores without proper feed system modifications. Ultrafine crushing (<20mm) requires secondary or tertiary crushing stages.
