1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing persistent bottlenecks and rising operational costs in your aggregate production line? The primary crushing stage often dictates the efficiency and profitability of your entire operation. Les défis courants incluent:

Temps d'arrêt imprévus: Bearing failures or component wear from uncrushable material lead to production halts, coûtant des milliers de dollars par heure en perte de production.
Sortie incohérente & Forme du produit: Poorly graded final product with excessive flaky content fails to meet stringent project specifications, leading to material rejection or reduced market value.
High Maintenance Labor & Parts Costs: Frequent manual adjustments, lubrication routines, and reactive part replacements strain maintenance budgets and crew time.
Inefficacité énergétique: Older crusher designs consume excessive power relative to tonnage produced, ayant un impact direct sur vos résultats.
Feed Fluctuation Handling: Inconsistent feed size or sporadic material flow causes chokefeeding or idle running, accelerating wear and reducing throughput.

Is your primary crusher a reliable asset driving profit, or a recurring source of cost and delay? The right foundation is critical.

2. APERÇU DU PRODUIT

Le [Nom de votre entreprise] Concasseur à mâchoires primaire est un poids lourd, singletoggle crushing machine engineered for the first stage of size reduction in quarrying, exploitation minière, et applications de recyclage par démolition. It is designed to process large, abrasive feed material (jusqu'à 80% of the gape opening) into consistent, coarse aggregate for further processing.

Flux de travail opérationnel:
1. Consommation alimentaire: Large runofmine rock or demolition concrete is loaded into the vibrating grizzly feeder (facultatif), which bypasses fines directly to the discharge conveyor.
2. Action écrasante: Material enters the fixed jaw chamber. The robust eccentric shaft drives the moving jaw in an elliptical motion, applying compressive force against the fixed jaw to break the rock.
3. Ajustement du paramètre de décharge: The crusher's closedside setting (CSS) is hydraulically adjustable from a central control point, allowing quick product size changes without manual shim manipulation.
4. Décharge & Transport: Crushed material exits at the bottom of the chamber onto a main product conveyor for transport to secondary crushing or stockpiling.

Champ d'application: Idéal pour le hard rock (granit, basalte), abrasive ore, et béton recyclé. Not recommended for sticky, plastic materials or as a standalone solution for producing fine sand.

6. SCÉNARIOS D'APPLICATION

Projet d'agrandissement de la carrière de granit

Défi: A large quarry needed to increase primary circuit throughput by 25% without expanding its footprint or primary feeder/conveyor infrastructure due to space constraints.
Solution: Replacement of an older doubletoggle jaw crusher with our highcapacity singletoggle model featuring a deeper chamber and optimized kinematics within the same foundational footprint.
Résultats: A atteint un 28% increase in average hourly tonnage while reducing specific energy consumption by 11%. Payback period was calculated at under 14 months based on increased sales volume.

Urban Recycling Contractor

Défi: Processing demolition concrete with frequent rebar contamination led to weekly downtime events from tramp metal jams, requiring full crew intervention over several hours each time.
Solution: Implementation of our jaw crusher with integrated hydraulic overload protection (tramp release system).
Résultats: Automatic release of uncrushable metal occurs within seconds without stopping the feed conveyor. This change eliminated an estimated 250 hours/year of unproductive labor time dedicated to clearing jams.
