1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Les coûts opérationnels croissants et la disponibilité imprévisible érodent-ils la rentabilité de votre circuit de concassage primaire? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the primary crushing stage is a critical bottleneck where failures have exponential downstream consequences. Les principaux défis comprennent:

Temps d'arrêt imprévus: Premature wear or failure of critical components like mantles, concaves, or bushings leads to production halts costing tens of thousands per hour.
Charge de maintenance élevée: Traditional designs require extensive labor, specialized tooling, et un temps considérable pour les changements de revêtement et l'entretien de routine, pulling skilled personnel from other critical tasks.
Débit incohérent & Taille du produit: Fluctuations in feed material hardness or size can cause chokefeeding or erratic discharge, compromising downstream process efficiency and final product specification.
Spiraling Operating Costs: The combined expense of replacement parts, energy consumption per ton processed, and maintenance labor directly impacts your costperton metric.

Is your current solution equipped to deliver the reliability, consistent throughput, and lower total cost of ownership required in today's competitive market? A reevaluation of your primary crushing technology is not just an equipment decision—it's a strategic financial one.

2. APERÇU DU PRODUIT

The modern China Gyratory Crusher represents a significant evolution in primary crushing technology. Conçu pour les gros volumes, continuousduty operation in largescale mining and aggregate production, it is designed to accept runofmine feed material directly from haul trucks.

Flux de travail opérationnel:
1. Acceptation des aliments: Large feed hopper receives direct dump from 200400 ton haul trucks.
2. Action écrasante: The eccentrically mounted main shaft causes the mantle to gyrate within the concave liner, appliquer une force de compression pour réduire la taille du matériau.
3. Décharge: Crushed product exits through the discharge opening at the bottom of the crusher (the setting), governed by the stroke and chamber design for consistent sizing.

Champ d'application & Limites:
Portée: Idéal pour les grandes capacités (5,000 15,000+ tph) primary crushing of abrasive ores (fer, cuivre, or), hard rock aggregates, and other nonmetallic minerals. Adapté aux installations fixes.
Limites: Not designed for smallscale operations or highly mobile applications. Requires a substantial capital investment and reinforced concrete foundation. Optimal performance requires consistent feed sizing within design parameters.
