1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

L’augmentation des coûts de maintenance et les temps d’arrêt imprévus érodent-ils vos marges de production globales ?? Taille d'alimentation incohérente, matériaux abrasifs, and the relentless demand for higher throughput create a cascade of operational challenges for plant managers. Ces problèmes ont un impact direct sur vos résultats: remplacement des pièces d'usure excessive, costly hourly labor for adjustments, and production shortfalls that delay project timelines and contract fulfillment.

Are you currently managing:
Premature Wear Failure: Remplacez-vous les doublures, manteaux, or jaws more frequently than the OEM projected lifespan, leading to high consumable costs and frequent stoppages?
Goulots d’étranglement du débit: Is your current crushing circuit unable to process peak feed volumes or handle varying material hardness without causing downstream delays?
Incohérence de la qualité des produits: Are you facing challenges in maintaining a consistent product gradation, leading to rejected loads or the need for reprocessing?
Complexité opérationnelle élevée: Does your equipment require constant manual monitoring and adjustment to maintain performance, tying up skilled labor?

A robust primary crushing station is the foundation of any efficient operation. The right jaw crusher must not only withstand punishment but also optimize the entire flow of material to your secondary and tertiary circuits.

2. APERÇU DU PRODUIT: BROYEUR À MÂCHOIRES ROBUSTE

This product is a stationary heavyduty jaw crusher engineered for primary crushing applications in quarrying, exploitation minière, et recyclage de construction à grande échelle. Il est conçu pour accepter de gros matériaux d'alimentation (jusqu'à 1200 mm) and reduce it to a consistent, manageable size for subsequent processing stages.

Flux de travail opérationnel:
1. Consommation alimentaire: Large shot rock or runofquarry material is loaded into the vibratory grizzly feeder, which bypasses subsize material and directs only oversize to the crusher.
2. Action écrasante: Material enters the aggressive crushing chamber where a steep nip angle and high inertia elliptical jaw motion apply compressive force to break rock.
3. Décharge & Autorisation: Le matériau broyé sort par un réglage latéral fermé à réglage hydraulique (CSS), ensuring precise control over final product size. An automatic toggle tensioning and clearing system protects the unit from tramp metal.

Champ d'application & Limites:
Portée: Idéal pour le hard rock (granit, basalte), minerais abrasifs, et débris de démolition en béton armé. Serves as the primary reduction unit in fixed plant configurations.
Limites: Non conçu pour être mouillé, matériaux collants sans scalpage préalable. Requires a stable concrete foundation and significant upfront capital investment compared to mobile units.

6. SCÉNARIOS D'APPLICATION

Projet d'agrandissement de la carrière de granit

Défi: An existing quarry needed to increase primary circuit output by over 30% without expanding its primary crusher footprint or foundation.
Solution Implementation of our JC1208HD jaw crusher with its deepchamber design replaced an older model of similar physical size.
Results Throughput increased by an average of 35%. The hydraulic toggle system allowed quick daily CSS checks without stopping production entirely.

Construction urbaine & Demolition Recycling Hub

Challenge Processing heavily reinforced concrete foundations produced excessive tramp metal incidents causing weekly shutdowns on their previous crusher.
Solution A JC1208HD was installed with its automatic hydraulic release system set at a conservative pressure threshold.
Results The system activated seven times in the first month releasing rebar bundles each event resulted in less than two minutes of downtime compared to previous halfday repairs No major component damage was sustained
