1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are escalating operational costs and unpredictable downtime eroding your primary crushing circuit’s profitability? Plant managers and engineering contractors consistently face critical challenges with their primary crushing assets:
Temps d'arrêt imprévus: Premature wear or failure of critical components can halt your entire processing line, costing tens of thousands per hour in lost production.
Coûts de maintenance excessifs: Changements fréquents de doublure, lengthy maintenance windows, and high parts consumption directly impact your bottomline operating expenditure.
Débit incohérent: Inefficient crushing chambers or suboptimal feed conditions lead to fluctuating tonnage, creating bottlenecks for downstream processes.
Consommation d'énergie élevée: Older or poorly designed crushers operate with low mechanical efficiency, making power costs a significant and growing operational burden.
Rigidity to Feed Variation: Hard, abrasive ores or unexpected feed sizes can cause chokeups or accelerated wear, forcing production rate compromises.

Is your operation in need of a robust, highcapacity primary crusher engineered not just for peak performance, but for sustained reliability and lower total cost of ownership?

2. APERÇU DU PRODUIT

A Gyratory Crusher is a stationary primary crushing machine central to largescale mining and aggregate operations. It utilizes a gyrating mantle within a concave housing to compress and fracture large feed material (typically above 1 meter in size) en plus petit, manageable rock for secondary processing.

Flux de travail opérationnel:
1. Consommation alimentaire: Runofmine ore or large quarry rock is directed into the top of the crusher’s deep, rugged chamber via haul trucks or feeders.
2. Concassage compressif: The eccentrically driven mantle gyrates within the stationary concave liners, applying compressive force to reduce particle size through repeated cycles.
3. Décharge: Crushed material gravitates downward through the narrowing chamber until it reaches the desired size and exits through the discharge opening at the bottom.

Champ d'application & Limites:
Portée: Idéal pour les tonnages élevés (1,500+ TPH) primary crushing applications in hard rock mining (cuivre, minerai de fer, or), large aggregate quarries, and major industrial mineral processing. Excels with abrasive and highstrength materials.
Limites: Requires significant capital investment and substantial physical footprint. Not suitable for smallscale operations, mobile plants, or handling highly plastic or claybound materials that may cause packing.
