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'une usine de concassage de pierre de 250 300 tph sont importants: unpredictable throughput fluctuations leading to missed delivery schedules, excessive wear part costs from inefficient crushing actions, and high energy consumption per ton of finished product. Downtime for maintenance or unplanned repairs can cost thousands per hour in lost production and idle labor. Are you questioning how to achieve consistent, specified output without constant oversight? Is your current plant configuration failing to adapt to varying feed material hardness? The solution lies not in pushing machinery harder, but in deploying an intelligently engineered 250300tph stationary crushing and screening plant designed for sustained, costeffective operation.

2. APERÇU DU PRODUIT

This solution is a complete stationary crushing and screening plant engineered for a nominal output range of 250 à 300 tonnes métriques par heure (tph) de granulat fini. It is configured for primary, secondaire, and tertiary crushing stages to produce up to 5 calibrated product sizes from hard rock (granit, basalte) et matériaux abrasifs.

Flux de travail opérationnel:
1. Réduction primaire: Matière première de grande taille (jusqu'à 750 mm) est systématiquement introduit dans un concasseur à mâchoires primaire robuste pour une réduction initiale de la taille.
2. Concassage secondaire & Dépistage: Crushed material is conveyed to a secondary cone crusher for further reduction. A primary screen separates sized material, routing oversize back for recrushing.
3. Façonnage tertiaire & Dimensionnement final: Pour produits de hautes spécifications comme les gravillons ou le sable manufacturé, a tertiary impact crusher or vertical shaft impactor (TOUT LE MONDE) provides final shaping. Subsequent screening decks ensure precise gradation control.

Champ d'application & Limites:
Portée: Idéal pour les opérations de grandes carrières, grands projets d’infrastructures nécessitant une production de granulats sur place, and dedicated aggregate supply yards serving regional markets.
Limites: Nécessite une stabilité, prepared feed material; not designed for mobile or semimobile applications without significant modification. Site requires adequate foundation engineering and space for the plant footprint and stockpiling.
