1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de granulats à volume élevé et êtes-vous confronté à des goulots d'étranglement persistants qui érodent la rentabilité ?? Pour les directeurs d’usine et les entrepreneurs en ingénierie, un 250300 TPH usine de concassage de pierre est un atout de production critique, Pourtant, des défis opérationnels courants peuvent nuire considérablement à son retour sur investissement.. These include unpredictable downtime from component failures under continuous heavy load, inconsistent final product gradation leading to premium product loss, and escalating maintenance costs from abrasive wear. En outre, inefficient power utilization and inflexible configurations that cannot adapt to varying feed materials or product specifications create recurring inefficiencies. How do you ensure your crushing circuit delivers its rated 300 tonperhour capacity consistently, maintains precise product specs with minimal waste, and operates with predictable maintenance costs? The specification of the plant itself is the foundational answer.

2. APERÇU DU PRODUIT

This specification outlines a complete, stationnaire CE Marked 250300tph Stone Crushing Plant, designed for highvolume production of aggregates for construction, base de route, et ballast ferroviaire. The plant is engineered as a threestage crushing and screening circuit for processing mediumhard to hard stone such as granite, basalte, ou du calcaire.

The operational workflow follows a logical, efficient path:
1. Concassage primaire: Matière première de grande taille (≤750mm) est réduit par un concasseur à mâchoires primaire robuste.
2. Secondaire & Concassage Tertiaire: The output is conveyed to a cone crusher for further size reduction, ensuring optimal particle shape.
3. Dépistage & Stockage: Material is classified via multideck vibrating screens; les surdimensionnés sont recyclés, while correctly sized fractions are conveyed to designated stockpiles.

Application scope includes largescale quarry operations, major infrastructure project support sites, et des chantiers d'approvisionnement en granulats dédiés. A key limitation is that this plant configuration is designed as a stationary installation; for frequent relocation, a modular or mobile variant would be more appropriate.
