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, yet its performance directly dictates your bottom line. Les défis opérationnels courants comprennent:
Débit incohérent: Fluctuations in feed material hardness or size leading to an average output below the 280tph design target, causing project delays and missed delivery schedules.
Temps d'arrêt excessif: Frequent mechanical failures in key components or lengthy changeover times for maintenance, resulting in hundreds of lost production hours annually.
Coûts opérationnels élevés: Uncontrolled wear part consumption, inefficient power draw per ton of processed material, and the labor intensity of routine monitoring.
Variabilité de la qualité des produits: Inability to consistently meet multiple spec products (par ex., 05mm, 1020mm, 2040mm) simultaneously due to inflexible or poorly calibrated crushing stages.
Limites d'évolutivité: A fixed plant configuration that cannot adapt to changing project demands or feed materials without significant capital reinvestment.

La question centrale est: how do you select a 250300tph crushing plant that transforms these cost centers into reliable, predictable production?

2. APERÇU DU PRODUIT

Ce produit est un complet, stationnaire 250300 TPH Hard Stone Crushing and Screening Plant. It is engineered for continuous, highvolume production of aggregates for large infrastructure projects, commercial concrete batching, and road base construction.

Flux de travail opérationnel:
1. Concassage primaire: Matière première de grande taille (≤750mm) is reduced to ≤200mm by a robust primary jaw crusher.
2. Secondaire & Concassage Tertiaire: Material is conveyed to a cone crusher circuit for further reduction, producing precisely shaped intermediates.
3. Dépistage & Classification: Multipledeck vibrating screens separate crushed material into specified finished product sizes.
4. Recirculation: Oversize material is automatically returned via conveyors to the appropriate crusher for reprocessing (conception en circuit fermé).
5. Stockage: Finished aggregates are conveyed to designated stockpiles for loadout.

Champ d'application & Limites:
Portée: Idéal pour le traitement du granit, basalte, cailloux de rivière, and other abrasive materials with compressive strength up to 350MPa. Suited for permanent quarry sites or longduration (3+ année) project bases.
Limites: Not designed as mobile or semimobile equipment; relocation requires disassembly. Maximum feed size and final capacity are contingent on specific material characteristics. Not optimal for processing sticky or highclay content materials without prescreening/scalping modifications.
