1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing the high costs and operational bottlenecks of secondary and tertiary crushing? Inefficient reduction of aggregates, béton recyclé, or industrial minerals directly impacts your bottom line. Les défis courants incluent:
Coûts d’usure excessifs: Premature failure of wear parts in abrasive applications leads to unpredictable maintenance budgets and frequent stoppages.
Product Shape Limitations: Poorly shaped cubical product from your current process can reduce the market value of your aggregates and increase reject rates in downstream applications.
Uncontrolled Fines Generation: Overcrushing material results in excessive, often unsellable fines, wasting energy and reducing yield of premiumsized fractions.
Rigidité dans l'application: A fixed crushing chamber struggles with fluctuating feed materials (par ex., from demolition recycling), causing blockages or inconsistent throughput.
Complexité opérationnelle élevée: Systems requiring frequent manual adjustment for product size changes increase labor time and the risk of human error.

What if your crushing circuit could deliver consistent, spec product with lower costperton, greater flexibility, and simplified control? The solution lies in selecting a purposeengineered impact crusher.

2. APERÇU DU PRODUIT

A modern impact crusher is a continuousfeed machine designed for size reduction through highspeed impact forces. It accelerates feed material via a rotor assembly before propelling it against stationary anvils or curtains, causing fracture along natural grain boundaries.

Flux de travail opérationnel:
1. Alimentation & Accélération: Material is introduced into the crushing chamber and seized by massive rotormounted blow bars.
2. Impact & Fracture: The rotor hurls material against adjustable impact aprons or anvils, achieving primary breakage.
3. Recirculation & Secondary Breakage: Larger pieces are recirculated within the chamber for further impacts (in a horizontal shaft impactor configuration).
4. Dimensionnement & Décharge: Crushed material exits through an adjustable gap between the rotor and the aprons/curtains, determining the final product top size.

Champ d'application: Ideal for medium to low abrasivity materials like limestone, béton/asphalte recyclé, débris de démolition, and industrial minerals where particle shape is a priority. It is commonly used as a secondary or tertiary crusher.

Principales limites: Not typically suited as a primary crusher for very large feed (exceeding ~40 inches). Performance and wear life degrade significantly with highly abrasive materials (par ex., some igneous rocks, silicarich sands) compared to compressionbased crushers; evaluation of total operating cost is essential.
