1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing gold ore processing operations where equipment reliability, conformité environnementale, and total cost of ownership directly impact your bottom line? Les défis courants incluent:
Regulatory Shutdown Risk: Noncompliant machinery containing restricted substances (par ex., plomb, cadmium, mercure) can lead to costly fines, import/export delays, and operational halts in regulated markets.
CorrosionInduced Downtime: Standard crusher components in aggressive sulphide or wet ore environments corrode prematurely, requiring frequent replacement and unplanned maintenance stops.
Contamination Concerns: Equipment materials that leach or shed particulates can complicate the leaching circuit and affect final gold recovery purity.
High Lifetime Cost: The true cost of a crusher isn't just the purchase price. It's the sum of energy consumption, liner wear rates, unscheduled maintenance labor, and lost processing time.

How do you specify crushing equipment that meets stringent international RoHS directives without compromising on durability or throughput for hard, abrasive gold ores? The solution requires an OEM factory engineered from the ground up for compliant performance.

2. APERÇU DU PRODUIT

Our solution is a line of Primary and Secondary Jaw Crushers and Cone Crushers specifically engineered for RoHS Compliant Gold Ore Crushing. These machines are built in our OEM factory with full control over material sourcing and manufacturing processes to ensure global compliance.

Flux de travail opérationnel:
1. Consommation alimentaire: Runofmine (ROM) gold ore is fed into a robust, RoHScompliant vibrating grizzly feeder.
2. Réduction de la taille primaire: Ore is crushed by a heavyduty jaw crusher utilizing compliant highmanganese steel jaws to achieve initial size reduction.
3. Concassage secondaire: Material is conveyed to a cone crusher for further reduction to optimal mill feed size (typically 25mm).
4. Décharge & Conveyance: Consistently sized ore is discharged onto conveyor systems with minimal dust generation for transport to the next processing stage.

Champ d'application & Limites:
Portée: Ideal for stationary or semimobile hard rock gold processing plants targeting EU and other regulated markets. Effective on quartz vein, sulphidebearing, and alluvial deposit ores.
Limites: Not designed as a standalone solution for entire mineral processing; functions as the core crushing module within a broader circuit. Maximum feed size and capacity are modeldependent.

3. CARACTÉRISTIQUES PRINCIPALES

RoHSCompliant Material Specification | Base technique: Substitution of restricted substances (Pb, Cd, Hg, Cr6+, PBBs/PBDEs) in electrical components, revêtements, scellés, and alloys. | Avantage opérationnel: Guarantees unimpeded shipment and operation in regulated jurisdictions, eliminating compliance audit failures. | Impact sur le retour sur investissement: Avoids project delays/fines (often exceeding €50k per incident) and protects brand reputation for exportoriented operations.

CorrosionResistant Chamber Design | Base technique: Use of specified stainless steels and composite polymer liners in nonwear areas prone to acid/sulphide attack. | Avantage opérationnel: Extends service intervals in wet or chemically aggressive ore conditions by reducing nonmechanical degradation. | Impact sur le retour sur investissement: Reduces chamber inspection frequency by an estimated 3040%, lowering labor costs and increasing plant availability.

HighEfficiency Crushing Geometry | Base technique: Optimized nip angle and crushing chamber profile based on discrete element modeling (DEM) for gold ore characteristics. | Avantage opérationnel: Increases throughput per kWh while producing a more consistent product size distribution for improved downstream grinding efficiency. | Impact sur le retour sur investissement: Les données de terrain s'affichent jusqu'à 15% lower energy cost per tonne crushed compared to nonoptimized legacy designs.

Integrated Dust Suppression Porting | Base technique: Preengineered ports for dry fog or water spray system integration at primary dust generation points. | Avantage opérationnel: Significantly reduces respirable silica dust at the source, improving site safety and meeting occupational health regulations. | Impact sur le retour sur investissement: Lowers costs associated with standalone dust collection units and reduces housekeeping labor.

Modular Maintenance Design | Base technique: Hydraulic adjustment & clearing systems combined with accessible service points for wear liners and key components.| Avantage opérationnel: Your maintenance crew can perform liner changes and clearing procedures faster and with reduced safety risk.| Impact sur le retour sur investissement: Reduces typical liner change downtime by up to 25%, directly increasing annual operating hours.

OEM Factory Direct Quality Control | Base technique: Complete vertical integration from metallurgical sourcing to final assembly under one certified quality management system (OIN 9001).| Avantage opérationnel: Traceability of all components ensures consistent performance and simplifies aftermarket support.| Impact sur le retour sur investissement: Eliminates quality variances from thirdparty assemblers, leading to longer mean time between failures (MTBF).
