1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Su operación de manipulación de coque enfrenta cuellos de botella persistentes y costos crecientes?? Para gerentes de planta y contratistas de ingeniería, the screening phase is a critical pressure point. Los desafíos comunes incluyen:
Excessive Downtime for Screen Deck Changes: Frequent blinding and wear from abrasive coke fines lead to costly, unplanned shutdowns, detener toda su línea de procesamiento.
Gradación de producto inconsistente: Inefficient separation results in offspec coke (undersize in product or oversize in breeze), directly impacting product revenue and downstream process efficiency.
Alto mantenimiento & Costos de reemplazo: The abrasive nature of coke rapidly degrades screen panels and components, driving up spare parts inventories and labor expenses.
Fatiga estructural & Transmisión de vibración: Poorly isolated vibration damages support structures and creates unsafe working environments, leading to longterm capital repair costs.

Are you evaluating how to increase throughput reliability, reducir el costo total de propiedad, and ensure consistent product quality? El derecho Criba vibratoria de coque no es solo una maquina; it’s a strategic investment in operational stability.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A Criba vibratoria de coque es una máquina de cribado industrial de alta resistencia diseñada para el descalzado, apresto, and dedusting of metallurgical coke and coke breeze in quenching towers, blast furnace feed systems, and byproduct recovery plants.

Flujo de trabajo operativo:
1. Introducción al feed: Bulk coke from crushers or conveyors is evenly distributed onto the screen’s feed box.
2. Vibración estratificada: Alta intensidad, linear or elliptical motion stratifies the material, forcing fines downward while conveying oversize across the deck.
3. Separación precisa: Sized apertures on robust screen panels allow undersized particles (25mm breeze or other specified cuts) to pass through.
4. Descargar: Correctly sized product (p.ej., +25mm blast furnace coke) discharges from the deck end, while fines are collected underneath.

Ámbito de aplicación: Primary screening of hot or quenched metallurgical coke, sizing of foundry coke, removal of coke breeze from blast furnace feed. Not typically recommended for wet screening applications or extremely sticky materials without specialized modifications.
