1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une exploitation de granulats de moyenne à 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, un 250300 tph stone crushing plant is a critical production asset, yet common operational challenges directly impact your bottom line.

Débit incohérent: Fluctuations in feed size or hardness can cause chokeups or underutilization, failing to consistently hit the 250300 tph target and delaying project timelines.
Temps d'arrêt excessif pour la maintenance: Changements fréquents de doublure, défaillances de roulements, or conveyor issues lead to unplanned stoppages. Industry data indicates that each hour of downtime in this capacity range can cost thousands in lost production and labor.
Coûts opérationnels élevés: Spiking energy consumption from inefficient crushing chambers and escalating wear part costs due to suboptimal material flow consume your operating margin.
Variabilité de la qualité des produits: Inability to precisely control final product gradation leads to offspec material, resulting in waste, recrushing, or rejected loads.

Is your current solution robust enough to handle abrasive granite or basalt at rated capacity? Can your plant’s design minimize points of failure? It’s time to evaluate a system engineered for reliable, costperton efficiency.

2. APERÇU DU PRODUIT

This brochure details a stationary ROHS Compliant 250300 TPH Stone Crushing Plant, a complete turnkey solution designed for highvolume production of aggregates for construction, base de route, et ballast ferroviaire. The plant is configured for primary, secondaire, and tertiary crushing stages to produce precisely graded final products.

Flux de travail opérationnel:
1. Réduction primaire: Large feed (≤750mm) is introduced to a robust jaw crusher or primary impactor for initial size reduction.
2. Concassage secondaire & Dépistage: Crushed material is conveyed to a cone crusher for further reduction. A vibrating screen separates material to route oversized particles back for recrushing (circuit fermé) and allows correctly sized material to proceed.
3. Façonnage tertiaire & Dimensionnement final: For cubical product requirements, material may be sent to a tertiary vertical shaft impactor (TOUT LE MONDE). Final screening decks separate output into multiple specified aggregate fractions (par ex., 05mm, 510mm, 1020mm).

Champ d'application & Limites:
Portée: Idéal pour le hard rock (granit, basalte), calcaire, and river gravel processing. Suited for permanent quarry sites or longterm infrastructure projects requiring consistent, highvolume output.
Limites: Not designed as mobile or skidmounted equipment. Feed size and abrasiveness must align with engineered crusher chamber specifications. Maximum capacity is contingent on specific material characteristics.
