1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Está usted administrando una operación agregada de alto volumen y enfrentando cuellos de botella persistentes que erosionan la rentabilidad?? Para gerentes de planta y contratistas de ingeniería, a 250300 planta trituradora de piedra tph es un activo de producción crítico, Sin embargo, los desafíos operativos comunes pueden socavar significativamente el retorno de la inversión.. These include unpredictable downtime from component failures under continuous heavy load, inconsistent final product gradation leading to premium product loss, and escalating maintenance costs from abrasive wear. Además, inefficient power utilization and inflexible configurations that cannot adapt to varying feed materials or product specifications create recurring inefficiencies. How do you ensure your crushing circuit delivers its rated 300 tonperhour capacity consistently, maintains precise product specs with minimal waste, and operates with predictable maintenance costs? The specification of the plant itself is the foundational answer.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This specification outlines a complete, estacionario CE Marked 250300tph Stone Crushing Plant, designed for highvolume production of aggregates for construction, base de la carretera, y lastre ferroviario. The plant is engineered as a threestage crushing and screening circuit for processing mediumhard to hard stone such as granite, basalto, o piedra caliza.

The operational workflow follows a logical, efficient path:
1. Trituración Primaria: Material de alimentación grande (≤750 mm) se reduce mediante una robusta trituradora de mandíbulas primaria.
2. Secundario & Trituración Terciaria: The output is conveyed to a cone crusher for further size reduction, ensuring optimal particle shape.
3. Cribado & Almacenamiento: Material is classified via multideck vibrating screens; el tamaño grande se recircula, while correctly sized fractions are conveyed to designated stockpiles.

Application scope includes largescale quarry operations, major infrastructure project support sites, y patios de suministro de agregados dedicados. A key limitation is that this plant configuration is designed as a stationary installation; for frequent relocation, a modular or mobile variant would be more appropriate.
