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 entrepreneurs en ingénierie, the core challenges in primary size reduction often include:

Coûts de maintenance élevés & Temps d'arrêt: Changements fréquents de doublure, défaillances de roulements, and unplanned stoppages for crusher repairs directly impact your bottom line. Can your operation afford 48+ hours of lost production for major component replacement?
Sortie incohérente & Forme du produit: Poorly graded aggregate with excessive flaky material fails to meet specifications, leading to rejected loads and reduced revenue per ton. Is your current equipment delivering the consistent cubicity required for highvalue asphalt and concrete mixes?
Consommation d'énergie excessive: Plus vieux, inefficient drive systems and poor chamber designs result in high kWhperton costs, a significant variable in your operational expenditure.
Limites de configuration rigides: Fixed crusher setups struggle to adapt to varying feed materials or changing product requirements, forcing compromises in either throughput or final product quality.
Coût total de possession élevé (Coût total de possession): Beyond the initial purchase price, hidden costs from parts consumption, consommation d'énergie, and labor for adjustments create an unsustainable financial burden over the equipment’s lifecycle.

La question centrale est: comment pouvez-vous obtenir un, costperton crushing without compromising on product quality or operational flexibility?

2. APERÇU DU PRODUIT

This product is a heavyduty jaw crusher engineered as a primary stone crusher machine for robust, réduction de gros volumes de roche dure, granit, basalte, et gravier de rivière. It is designed as a private label solution for OEMs and large distributors seeking reliable performance with competitive pricing.

Flux de travail opérationnel:
1. Consommation alimentaire: Matière première de grande taille (jusqu'à l'ouverture d'alimentation spécifiée) est chargé dans la mangeoire vibrante pour grizzlis (facultatif), qui contourne les amendes pour augmenter l'efficacité de la chambre primaire.
2. Concassage primaire: Le matériau entre dans l'ensemble de mâchoires fixe et mobile. The elliptical motion of the movable jaw applies compressive force against the fixed jaw, breaking stone via mechanical pressure.
3. Ajustement du paramètre de décharge: The crushed material exits at the bottom aperture. Le cadre fermé (CSS) is hydraulically adjustable to control the final product size without manual shim changes.
4. Transport du produit: Crushed aggregate is discharged onto the main plant conveyor for transport to secondary screening or stockpiling.

Champ d'application & Limites:
Portée: Idéal pour les usines de carrière stationnaires, opérations minières à grande échelle, and major infrastructure project sites requiring primary crushing of abrasive materials with uniaxial compressive strength up to 320 MPa.
Limites: Not designed as a standalone solution for finished aggregate; requires secondary and tertiary stages for most specification products. Not suitable for recycling mixed demolition waste without significant prescreening due to risk of tramp metal.
