1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Votre concasseur principal est le goulot d'étranglement. Chaque heure d'arrêt imprévu sur un 600 TPH jaw crusher costs your operation an estimated $15,000 à $25,000 in lost production and idle downstream equipment. You are facing escalating wear costs on manganese liners that fail prematurely due to feed material variability. Your current setup struggles with slabby material, causing bridging at the feed opening and reducing throughput by 1218%. Are you constantly adjusting the closed side setting (CSS) to maintain product consistency, only to find your power draw spiking and your maintenance team scrambling? The operational challenge is clear: you need a crushing solution that delivers consistent reduction ratios, maximise la disponibilité, and lowers your cost per ton without requiring a complete plant redesign.

2. APERÇU DU PRODUIT

Le HighCapacity Jaw Crusher is a primary reduction machine designed for continuous, heavyduty service in hard rock mining and largescale aggregate operations. It utilizes a compression crushing mechanism between a fixed jaw die and a moving jaw die, powered by a large eccentric shaft.

Flux de travail opérationnel:
1. Consommation alimentaire: Runofmine (ROM) material up to 1,200mm is fed into the Vshaped crushing chamber via a vibrating grizzly feeder.
2. Cycle de compression: L'arbre excentrique tourne, driving the pitman arm and toggle plate to move the swing jaw in an elliptical motion, compressing rock against the fixed jaw.
3. Fracture & Décharge: Rock is fractured along natural stress lines. Once reduced below the CSS, material gravitydischarges onto a discharge conveyor.
4. Ajustement des paramètres: Hydraulic CSS adjustment allows for quick changes to product size without manual shimming.
5. Protection contre les surcharges: A hydraulic relief system activates if uncrushable material enters the chamber, protecting the main frame and shaft.

Champ d'application: Concassage primaire de granit, basalte, quartzite, et minerai de fer. Limites: Ne convient pas aux collants, matériaux liés à l'argile (provoque un emballage); higher wear costs per ton compared to gyratory crushers in very high tonnage (>2,000 TPH) candidatures.

8. FAQ

Q: Can this jaw crusher handle wet or sticky material?
UN: Non. The compression action of a jaw crusher is not effective for sticky, claybound feed. Pour les matériaux avec >8% moisture and high clay content, we recommend a feederbreaker or impact crusher.

Q: What is the typical lead time for the JC1500?
UN: Le délai de livraison standard est 1416 semaines à compter de la confirmation de la commande. The Advanced Package may require 1820 weeks due to hydraulic component sourcing.

Q: Comment le système hydraulique CSS affecte-t-il les coûts de maintenance?
UN: Les données de terrain montrent un 25% reduction in annual maintenance labor costs. The system eliminates manual shimming, which is a common source of toggle plate misalignment and premature wear.

Q: Quelle est la couverture de la garantie?
UN: 24 mois à compter de la mise en service ou 5,000 heures d'ouverture, selon la première éventualité. The warranty covers defects in materials and workmanship but excludes normal wear items (la mâchoire meurt, plaques à bascule, joues).

Q: Can this crusher be integrated into an existing plant with a 150 Moteur kW?
UN: Oui, but performance will be limited. The JC1500 is designed for 160200 kW. Using a 150 kW motor will reduce throughput by approximately 1520% and may cause motor overload during peak load conditions.

Q: What is the recommended foundation depth?
UN: A reinforced concrete foundation of minimum 1.5 meters depth is required, with a mass at least 2.5 times the crusher weight (environ 210 tons of concrete). We provide detailed foundation drawings with the order.

Q: How often should the toggle plate be replaced?
UN: Dans des conditions normales de fonctionnement, the toggle plate should be inspected every 500 hours and replaced every 2,0003,000 heures. Frequent breakage indicates an overload condition or incorrect CSS setting.
