1. ABERTURA ACIONADA POR PAINPOINT

Are you managing a midtolarge scale aggregate operation and facing persistent bottlenecks that erode profitability? Para gerentes de fábrica e empreiteiros de engenharia, o 250300 TPH capacity range is critical, yet often problematic. Os desafios comuns incluem:
Taxa de transferência 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.
Tempo de inatividade excessivo para manutenção: 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 rodoviária, 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. VISÃO GERAL DO PRODUTO

A planta de britagem de pedra OEM 250300tph é uma unidade completa, stationary crushing circuit engineered for highvolume production of certified aggregates from hard rock formations like granite, basalto, e pedra do rio. It is designed as a primarytotertiary processing system for contractors and mining operations requiring consistent, highyield output.

Fluxo de Trabalho Operacional:
1. Redução Primária: Dumpfed material is crushed by a robust primary jaw crusher, reducing large feed (≤750 mm) to a manageable size for secondary processing.
2. Secundário & Britagem Terciária: Material is conveyed to a cone crusher(é) para maior redução de tamanho, producing intermediate aggregates. A tertiary impact crusher may be integrated for shaping applications.
3. Classificação de tamanho: Crushed material is routed through multideck vibrating screens to precisely separate product sizes (por exemplo, 05milímetros, 510milímetros, 1020milímetros, 2031.5milímetros).
4. Recirculação & Estoque: Oversize material is automatically returned via closedcircuit conveyors for recrushing. Onspec product is conveyed to designated stockpiles.

Escopo de aplicação & Limitações:
Escopo: Ideal for large infrastructure projects (rodovias, ferrovias), commercial concrete batching plants supply, and permanent quarry sites.
Limitações: 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.
