1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Les coûts opérationnels croissants et la disponibilité imprévisible érodent-ils la rentabilité de votre circuit de concassage principal ?? Plant managers and engineering contractors consistently face critical challenges with their primary crushing stations:

Temps d'arrêt imprévus: Bearing failures or mainshaft issues can halt your entire processing line for days, coûtant plus de $50,000 par heure de production perdue.
Coûts de maintenance élevés & Travail: Fréquent, laborintensive liner changes and lubrication system overhauls consume both budget and skilled technician hours.
Débit incohérent & Taille du produit: Fluctuations in feed material hardness lead to variable output, creating bottlenecks for downstream milling and processing equipment.
Consommation d'énergie excessive: Older or inefficient gyratory crusher designs draw disproportionate power relative to tonnage crushed, impactant directement les dépenses opérationnelles.

Comment obtenir un débit plus élevé avec une plus grande fiabilité tout en contrôlant le coût total de possession? The solution requires a fundamental reassessment of your primary gyratory crusher technology.

2. APERÇU DU PRODUIT: BROYEUR GIRATOIRE ROBUSTE

This heavyduty primary gyratory crusher is engineered for the continuous, hightonnage crushing of runofmine ore and blasted rock. It serves as the first mechanical reduction stage in mineral processing and aggregate production circuits.

Flux de travail opérationnel:
1. Alimentation: Large blasted material (jusqu'à 1,5 m de taille) is directed into the crushing chamber via a feed hopper.
2. Action écrasante: The eccentrically driven mainshaft causes the mantle to gyrate, creating a progressive compressive crushing action against the stationary concave liners.
3. Décharge: Crushed product exits through the discharge opening at the bottom of the chamber, avec une taille déterminée par le réglage du côté fermé (CSS).

Champ d'application & Limites:
Portée: Idéal pour les grandes capacités (2,000 10,000+ tph) primary crushing applications in largescale mining, cuivre, minerai de fer, gold operations, and major quarry sites.
Limites: Not suitable for abrasive recycling materials without specific liner metallurgy. Nécessite une écurie, reinforced concrete foundation and significant headroom for maintenance. Initial capital investment is substantial, justified by decades of service.
