1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are unplanned breakdowns and inconsistent output crippling your aggregate production schedule? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the reliability of core crushing equipment directly dictates profitability. Common operational challenges with primary stone crushers include:

Temps d'arrêt excessif pour la maintenance: Frequent liner changes and component wear lead to production halts, coûtant des milliers de dollars par heure en perte de production et de main d'œuvre.
Gradation de produit imprévisible: Inconsistent feed size or wearrelated performance drift results in offspec aggregate, forcing recrushing or product downgrades.
Coûts opérationnels élevés: Rising energy consumption per ton and the recurring expense of premium wear parts erode project margins.
Vulnérabilité au Tramp Metal & Incassables: Unplanned incidents with contaminant materials can cause catastrophic damage, resulting in lengthy, expensive repairs.

Is your current primary crusher a constant source of operational risk and cost overrun? La solution ne réside pas seulement dans une machine, but in an engineered system built for predictable performance and total cost of ownership.

2. APERÇU DU PRODUIT

Le Curseur de mâchoire est un robuste, heavyduty primary crushing machine designed for the first stage of size reduction in quarrying, exploitation minière, et applications de recyclage par démolition. Its core function is to compressively fracture large feed material (typically runofmine or runofquarry rock) into manageable sizes for secondary processing.

Flux de travail opérationnel:
1. Consommation alimentaire: Matière première importante (jusqu'à 8090% de l'ouverture du concasseur) is loaded into the vibrating grizzly feeder ahead of the crusher.
2. Concassage compressif: Le matériau entre dans les plaques à mâchoires fixes et mobiles. The eccentric shaft drives the movable jaw in an elliptical motion, applying immense compressive force to the rock.
3. Décharge: Crushed material exits through the adjustable discharge opening at the bottom, avec une taille déterminée par le réglage du côté fermé (CSS).

Champ d'application & Limites:
Portée: Idéal pour les durs, matériaux abrasifs (granit, basalte, gravier de rivière). Adapté aux usines stationnaires et aux installations mobiles sur chenilles. Handles a wide variety of feed sizes.
Limites: Pas optimal pour le soft, nonabrasive stone where other crusher types may be more efficient. Requires consistent feed control to prevent choking. Output tends to be more elongated compared to cone crushers.
