1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing the high costs and operational disruptions associated with primary jaw crusher discharge? Your secondary crushing stage faces consistent challenges: consommation excessive de pièces d'usure provenant de matériaux d'alimentation abrasifs, temps d'arrêt imprévus pour les changements de revêtement, and inconsistent product gradation affecting downstream processes. These issues directly impact your plant’s throughput and profitability.

Considérez votre opération actuelle. How often are you replacing hammers or blow bars? What is the true cost of a multihour shutdown to address a damaged rotor or replace worn components? Is your final product shape meeting spec without requiring additional processing steps? The efficiency of your secondary crushing circuit is pivotal. Un robuste, wellengineered high quality impact crusher is not merely another piece of equipment; it is the critical component that determines your aggregate shape, product yield, and longterm operating expenditure.

2. APERÇU DU PRODUIT

A high quality impact crusher is a heavyduty machine designed for the secondary or tertiary reduction of materials such as limestone, béton, asphalte, et débris de démolition. It utilizes impact force rather than compression to fracture material.

Flux de travail opérationnel:
1. Entrée de flux: Sized feed from a primary crusher is directed into the feed opening.
2. Accélération & Impact: Material enters the chamber and is struck by highspeed rotating hammers (barres de soufflage) mounted on a solid rotor.
3. Fragmentation: Material shatters upon impact with the blow bars and is subsequently thrown against fixed impact plates (doublures de tablier).
4. Contrôle & Décharge: The fractured material passes through adjustable aprons or grates, which control the output size. The final product is discharged onto a conveyor system.

Champ d'application: Ideal for producing cubical aggregate for asphalt and concrete, recycling construction and demolition waste, and processing mediumhard, nonabrasive to moderately abrasive materials.

Principales limites: Not typically suited for primary crushing of very large feed sizes or for processing highly abrasive materials (par ex., granit, piège à pierres) where compressionstyle crushers may offer superior wear life.

6. SCÉNARIOS D'APPLICATION

Usine de production de granulats – Carrière de calcaire

Défi: A large quarry’s existing secondary crusher produced excessive fines (<4mm) and flaky material, failing to meet premium concrete aggregate specifications. High wear rates were also driving up cost per ton.
Solution: Installation of a high quality impact crusher with a multichamber design optimized for limestone was implemented into the secondary position.
Résultats: Particle shape improved significantly, with the cubicity index rising from 72% à plus 90%. Yield of premiumgrade (+4mm) aggregate increased by 22%. Simultanément, wear metal consumption decreased by 30%, improving overall margin per ton processed.
