1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks that erode profitability? Para gerentes de planta y contratistas de ingeniería, el 250300 TPH capacity range is critical, yet often problematic. Los desafíos comunes incluyen:
Rendimiento inconsistente: Feed material variability causing output to fluctuate below the 250 TPH target, failing to meet project batching schedules and leading to costly penalties.
High PerTon Operating Costs: Premature wear on crusher liners and screens, combined with inefficient power distribution across multiple units, driving maintenance and energy expenses higher than budgeted.
Tiempo de inactividad excesivo para mantenimiento: Poorly coordinated plant layouts and components with staggered service intervals result in unplanned stops, reducing overall plant availability below 92%.
Product Quality Inflexibility: Inability to quickly adjust crusher settings and screen configurations to switch between railway ballast, base de la carretera, and concrete aggregates without halting production.

How do you consolidate a reliable 300 TPH output from varied feed material while controlling operational costs and maximizing plant uptime? The solution lies in a holistically engineered stationary crushing and screening plant designed specifically for this duty cycle.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The OEM 250300tph Stone Crushing Plant is a complete, stationary crushing circuit engineered for highvolume production of certified aggregates from hard rock formations like granite, basalto, and river stone. It is designed as a primarytotertiary processing system for contractors and mining operations requiring consistent, highyield output.

Flujo de trabajo operativo:
1. Reducción Primaria: Dumpfed material is crushed by a robust primary jaw crusher, reducing large feed (≤750 mm) to a manageable size for secondary processing.
2. Secundario & Trituración Terciaria: Material is conveyed to a cone crusher(s) for further size reduction, producing intermediate aggregates. A tertiary impact crusher may be integrated for shaping applications.
3. Clasificación de tamaño: Crushed material is routed through multideck vibrating screens to precisely separate product sizes (p.ej., 05milímetros, 510milímetros, 1020milímetros, 2031.5milímetros).
4. Recirculación & Almacenamiento: Oversize material is automatically returned via closedcircuit conveyors for recrushing. Onspec product is conveyed to designated stockpiles.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for large infrastructure projects (autopistas, ferrocarriles), commercial concrete batching plants supply, and permanent quarry sites.
Limitaciones: This is a stationary plant requiring foundational work and grid power connection. It is not suitable for frequent relocation. Optimal feed material should have an abrasion index (Ai) below .20 for expected wear part life.
