1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke screening operation a source of constant cost and disruption? Para gerentes de planta y contratistas de ingeniería, the challenges of screening bulk metallurgical coke directly impact throughput, calidad del producto, y presupuestos de mantenimiento. Los puntos débiles comunes incluyen:
Tiempo de inactividad excesivo: Frequent screen cloth changes due to rapid blinding and abrasion from sharp, hard coke particles halt your entire processing line.
Generación de multas descontroladas: Inefficient screening creates excessive 5mm fines, degrading product value and creating handling issues for blast furnace operations.
Altos costos de mantenimiento: The punishing environment leads to premature failure of screen decks, ballestas, y rodamientos, driving up spare parts inventories and labor hours.
Clasificación de productos inconsistente: Inadequate separation results in offspec material, leading to customer rejections or penalties tied to size distribution guarantees.
Ineficiencia energética: Poorly designed vibratory systems consume excess power without delivering proportional screening performance.

Are you seeking a robust solution that reduces total cost of ownership while ensuring consistent grade control? The right industrial coke vibration screen is engineered to address these exact operational challenges.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A heavyduty coke vibration screen is a highcapacity, linear motion screening machine designed for the scalping and precise size classification of hot or cold metallurgical coke. Its primary function is to separate crushed or processed coke into defined fractions (p.ej., +25mm coque de alto horno, 1025mm nut coke, 10mm brisa) with high efficiency and reliability.

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. Separación de tamaños: The dual eccentric shaft vibrator assembly drives the screen box on a linear path. Coke travels over sequentially finer screen cloths (typically wire mesh or polyurethane panels), with undersize material falling through each deck.
3. Descargar & Recopilación: Correctly sized fractions are discharged from separate discharge spouts into designated chutes or conveyors for stockpiling or further processing.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for sinter plants, sistemas de carga de alto horno, and coke handling terminals. Suitable for hot coke screening (with heatresistant components) up to ~200°C and cold screening applications.
Limitaciones: No diseñado para materiales pegajosos sin tratamiento previo.. El tamaño máximo de alimentación está limitado por la apertura de la plataforma y el diseño de la máquina.; typically handles feed up to 150200mm.
