1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation plagued by persistent bottlenecks and quality control issues? Para gerentes de planta que supervisan el cribado de coque, Los desafíos comunes impactan directamente el rendimiento y la rentabilidad.. La contaminación excesiva de finos en los flujos de productos puede provocar rechazos de clientes y pérdida de ingresos.. La tela de la pantalla se deslumbra con frecuencia debido a, highmoisture coke drastically reduces effective screening area, forcing premature shutdowns for manual cleaning. The constant impact abrasion from bulk coke leads to rapid wear of screen decks and components, generating high replacement part costs and unplanned maintenance windows. Vibration isolation failures transfer destructive forces to support structures, creating longterm integrity concerns and safety risks. How do you maintain specified size fractions consistently while extending equipment service life and maximizing plant uptime? The efficiency of your downstream blast furnace or smelting operation depends on the reliability of this critical separation stage.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Coke Vibration Screen is a heavyduty, highamplitude screening machine engineered for the scalping and precise size classification of metallurgical coke, coque de petróleo, and foundry coke. Its design prioritizes durability and material throughput in harsh, abrasive environments.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Bulk coke is fed onto the robust feed box, que distribuye uniformemente el material en todo el ancho de la plataforma de cribado principal.
2. HighEnergy Separation: The exciter drive generates a powerful linear or elliptical motion, aggressively conveying coke along the deck while forcing undersized particles through the screen apertures.
3. Fractional Discharge: Correctly sized product (demasiado grande) discharges from the deck's end, while fines (tamaño insuficiente) pass through to a lower collection chute or subsequent deck for further grading.

Ámbito de aplicación: Primary sizing of ovendischarged coke, eliminación de brisa (multas) from blast furnace feed, classification of recirculated coke in sinter plants, y aplicaciones de desempolvado.

Limitaciones: Not designed for ultrafine screening (8%) may require predrying or heated deck options.
