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 ?? Les défis d'un 250300 tph stone crushing plant are often clear: inconsistent feed material causing crusher stalls and wear, excessive downtime for liner changes and maintenance, high energy consumption per ton of output, and difficulty meeting strict aggregate specifications consistently. These issues translate directly to lost revenue. How much production are you losing during changeovers? What is the true cost of unplanned downtime on your project timelines? Are your operational costs under control, or are they being inflated by inefficient processes and premature component failure? A wellengineered, customized OEM 250300tph stone crushing plant is designed to systematically address these exact pain points.

2. APERÇU DU PRODUIT

This solution is a complete, heavyduty stationary or semistationary stone crushing plant engineered for reliable production of 250 à 300 metric tons per hour of crushed aggregate. It is not an offtheshelf product but a configured system built around core OEM crushers, écrans, and conveyors.

Flux de travail opérationnel:
1. Réduction primaire: Matière première de grande taille (jusqu'à 750 mm) is reduced by a robust primary jaw or gyratory crusher.
2. Concassage secondaire/tertiaire: Material is conveyed to secondary cone or impact crushers for further size reduction and shaping.
3. Dimensionnement & Classification: Crushed material passes through multideck vibrating screens to separate it into precise product fractions (par ex., 05mm, 510mm, 1020mm).
4. Stockage & Recirculation: Onspec material is conveyed to stockpiles. Oversize material is automatically recirculated back into the circuit for recrushing.

Champ d'application: Ideal for large quarry operations, grands projets d'infrastructures (autoroutes, chemins de fer), and commercial concrete/asphalt plants requiring highvolume, consistent aggregate supply.
Limites: Requires significant capital investment and planned site preparation. Optimal performance depends on correct system configuration for the specific feed material characteristics (abrasivité, teneur en silice, humidité).
