1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing a midtolarge scale aggregate production operation and facing persistent bottlenecks? Les défis d'une usine de concassage de pierre de 250 300 tph sont importants: inconsistent feed material degrading final product spec, unplanned downtime from component failure costing thousands per hour, and energy consumption eroding profit margins. Your plant’s output directly dictates project timelines and commercial viability.

Vivez-vous:
Throughput falling below 300tph due to inefficient crushing chamber design or improper screening, laisser des revenus sur la table?
Frequent maintenance stops for liner changes or bearing issues, creating unpredictable operational schedules?
High operational costs from excessive power draw and rapid wear part consumption?
Difficulty meeting stringent aggregate gradation requirements for asphalt or concrete mixes, conduisant au rejet du produit?

La question centrale est: comment pouvez-vous obtenir un, costperton production within the 250300tph range while maintaining product quality and controlling operational expenses?

2. APERÇU DU PRODUIT

This product description details a complete, stationnaire 250300tph Stone Crushing Plant designed for highvolume aggregate production in quarrying, exploitation minière, et grands projets d'infrastructures. It is engineered as a turnkey solution for contractors and mining companies requiring consistent output of highspecification aggregates.

Flux de travail opérationnel:
1. Concassage primaire: Matière première de grande taille (jusqu'à 750 mm) est réduit par un concasseur à mâchoires primaire robuste.
2. Dépistage intermédiaire & Écrasement: Le matériau précriblé est acheminé vers un concasseur à cône secondaire pour une réduction supplémentaire., tandis que les surdimensionnés sont recirculés.
3. Concassage Tertiaire/Fin: Pour les exigences de produits cubiques, a tertiary cone crusher or impact crusher processes material.
4. Projection finale & Tri: Multipledeck vibrating screens precisely separate output into finished product sizes (par ex., 05mm, 510mm, 1020mm).
5. Manutention des matériaux: A network of conveyors with centralized PLC control ensures efficient material transfer between stages.

Champ d'application: Idéal pour produire des agrégats pour la base des routes, béton, asphalte, et ballast ferroviaire. Convient au hard rock (granit, basalte) and mediumhard rock (calcaire).
Limites: Not designed for very soft, cohesive materials without significant configuration changes. Requires stable foundation and substantial electrical supply.
