1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

L’augmentation des coûts opérationnels et les temps d’arrêt imprévisibles érodent vos marges de production globales? Pour les directeurs d’usine et les spécialistes des achats, selecting a reliable yet costeffective primary crushing solution is a critical capital decision fraught with operational risks. Les défis courants incluent:

Coûts de maintenance excessifs: Changements fréquents de doublure, défaillances de roulements, and unplanned repairs directly impact your bottom line and labor allocation.
Débit incohérent & Forme du produit: Suboptimal crushing chambers lead to poor reduction ratios, amendes excessives, or irregular aggregate shape, affecting downstream process efficiency and product marketability.
Consommation d'énergie élevée: Inefficient drive systems and outdated crushing technology result in unsustainable power costs per ton of material processed.
Usure rapide dans les applications abrasives: When processing hard rock or highly abrasive feed material, component wear life can be catastrophically short, driving up costperton metrics.
Flexibilité de configuration limitée: Fixed crusher designs cannot adapt to changing feed stock or final product requirements without significant additional investment.

La question centrale devient: How can you secure a robust primary jaw crusher that delivers fundamental reliability and efficiency without the premium price tag of toptier brands?

2. APERÇU DU PRODUIT

The subject of this specification is a heavyduty Concasseur à mâchoires primaire, engineered as a costcompetitive entry in the stationary and portable crushing plant market. This machine is designed for the primary reduction of hard, abrasive materials such as granite, basalte, et gravier de rivière.

Flux de travail opérationnel:
1. Consommation alimentaire: Matière première de grande taille (jusqu'à l'ouverture d'alimentation spécifiée) est déposé dans la mangeoire vibrante pour grizzlis (facultatif) or directly into the crusher's deep crushing chamber.
2. Concassage par compression: The robust eccentric shaft drives the movable jaw plate in an elliptical motion against the fixed jaw plate, appliquer une immense force de compression pour fracturer la roche.
3. Ajustement du paramètre de décharge: The size of the crushed output product is controlled by hydraulically or mechanically adjusting the gap at the discharge point between the jaw plates.
4. Décharge de matière: Crushed material exits the chamber onto the main plant conveyor for transport to secondary crushing or screening stages.

Champ d'application & Limites:
Portée: Ideal for quarry primary crushing, opérations minières, et recyclage des déchets de construction à grande échelle. Suitable for integration into both fixed plant and trackmounted mobile setups.
Limites: Not designed as a tertiary crusher for producing sand or very fine aggregates. La taille et la capacité maximales de l'alimentation sont liées par les spécifications du modèle; exceeding these parameters will result in accelerated wear and potential damage.
