1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de production de granulats à moyenne ou grande échelle et faites-vous face à des goulots d'étranglement persistants qui érodent la rentabilité ?? Pour les directeurs d’usine et les entrepreneurs en ingénierie, a 250300tph stone crushing plant is a critical capital asset, Pourtant, des défis opérationnels courants peuvent nuire considérablement à son retour sur investissement..

Débit incohérent: Fluctuations in feed material hardness or size can cause chokeups or underutilization, ne pas réussir à frapper systématiquement le 250300 ton per hour target and delaying project timelines.
Temps d'arrêt opérationnel élevé: Frequent maintenance stops for wear part replacement or unplanned mechanical failures directly translate to lost revenue, often exceeding thousands of dollars per hour in idle capacity.
Consommation d'énergie excessive: Inefficient crushing chambers and poorly matched componentry can lead to disproportionately high power costs per ton of finished aggregate.
Variabilité de la qualité des produits: Inability to precisely control final product cubicity and gradation leads to offspec material, reducing its market value or causing rejections.
Dégradation rapide des pièces d’usure: The wrong configuration for your primary rock type accelerates wear in crushers, écrans, et convoyeurs, creating unpredictable cost spikes and inventory headaches.

Is your current setup delivering predictable throughput with controlled operational expenses? Can you reliably meet stringent aggregate specifications while maintaining a low costperton metric? The following solution addresses these exact engineering and commercial challenges.

2. APERÇU DU PRODUIT

Cette installation de concassage de pierre stationnaire de 250 300 tph est une installation complète, hardrock processing circuit engineered for continuous, production en grande série de granulats pour la construction, base de route, et ballast ferroviaire. It is designed as a multistage crushing and screening system for processing mediumhard to hard stones such as granite, basalte, cailloux de rivière, et du calcaire.

Flux de travail opérationnel:
1. Concassage primaire: Matière première de grande taille (≤750mm) est réduit par un concasseur à mâchoires primaire robuste ou un concasseur giratoire.
2. Secondaire & Concassage Tertiaire: La sortie est transmise au secondaire (concasseur à cône) and optionally tertiary (cone or impact crusher) stages for further size reduction and shape refinement.
3. Dépistage & Classification: Material is routed through vibrating screens to separate it into precise product fractions (par ex., 05mm, 510mm, 1020mm).
4. Manutention des matériaux & Stockage: Closedcircuit conveyors recirculate oversize material back to the appropriate crusher, tandis que le produit conforme aux spécifications est acheminé vers des stocks désignés.

Champ d'application & Limites:
Portée: Idéal pour les opérations de grandes carrières, major infrastructure projects requiring dedicated onsite supply, and commercial aggregate suppliers serving regional markets.
Limites: This is a stationary plant configuration requiring foundational work and substantial electrical supply. Il ne convient pas aux déménagements fréquents. Extremely abrasive or sticky materials may require specific liner configurations and more intensive maintenance protocols.
