1. ABERTURA ACIONADA POR PAINPOINT

Você está gerenciando uma operação agregada de alto volume e enfrentando gargalos persistentes que prejudicam a lucratividade?? Para gerentes de fábrica e empreiteiros de engenharia, um 250300 planta de britagem de pedra tph é um ativo crítico de produção, no entanto, desafios operacionais comuns podem prejudicar significativamente o retorno do investimento. 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. Além disso, 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. VISÃO GERAL DO PRODUTO

This specification outlines a complete, estacionário CE Marked 250300tph Stone Crushing Plant, designed for highvolume production of aggregates for construction, base rodoviária, e lastro ferroviário. The plant is engineered as a threestage crushing and screening circuit for processing mediumhard to hard stone such as granite, basalto, ou calcário.

The operational workflow follows a logical, efficient path:
1. Britagem Primária: Material de alimentação grande (≤750 mm) é reduzido por um robusto britador de mandíbula primário.
2. Secundário & Britagem Terciária: The output is conveyed to a cone crusher for further size reduction, ensuring optimal particle shape.
3. Triagem & Estoque: Material is classified via multideck vibrating screens; tamanho grande é recirculado, while correctly sized fractions are conveyed to designated stockpiles.

Application scope includes largescale quarry operations, major infrastructure project support sites, e pátios dedicados de fornecimento agregado. 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.
