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, les principaux défis du concassage primaire se concentrent souvent sur trois domaines critiques: excessive maintenance cycles that halt entire processing lines, unsustainable wear part costs that consume your budget, and inconsistent output gradation that compromises downstream efficiency. Each hour of unplanned stoppage can cost thousands in lost production and labor. How do you select a primary crusher that delivers not just raw power, mais des performances prévisibles et une maîtrise totale des coûts? The solution requires equipment engineered to address these specific operational and financial pressures from the ground up.

2. APERÇU DU PRODUIT

Le Curseur de mâchoire est un poids lourd, compressive force primary crusher engineered for the first stage of size reduction in quarrying, exploitation minière, et applications de recyclage par démolition. Its operational workflow is mechanically straightforward yet highly robust: 1) Material is fed into the crushing chamber between a fixed and a reciprocating jaw plate. 2) The movable jaw exerts immense compressive force onto the feed material, breaking it against the stationary jaw. 3) The crushed product discharges by gravity through the adjustable gap at the bottom of the chamber, déterminer la taille du produit final.

Its application scope is ideal for hard, matériaux abrasifs comme le granit, basalte, et béton recyclé. A key operational limitation is its typically coarser product shape compared to cone crushers, making it less suitable as a standalone solution when a high proportion of fines or specific cubicity is required in the final product without secondary crushing stages.

6. SCÉNARIOS D'APPLICATION

Extraction de roches dures – Production de granulats de granit

Défi: A granite quarry faced frequent jaw die changes every 3 months due to extreme abrasion, causing 12+ hours of downtime per event and high consumable costs.
Solution: Implementation of a heavyduty jaw crusher with profileoptimized manganese jaws and an automated greasing system.
Résultats: Wear life extended to over 5 months per set. Combined with faster hydraulic CSS adjustment, annual crusherrelated downtime was reduced by an estimated 28%, contributing directly to a 7% augmentation du volume de production annuel.

Recyclage des déchets de démolition urbaine
