1. Addressing Critical Screening Challenges in Coke Handling

Is your coke screening operation a source of consistent cost overruns and production bottlenecks? Inefficient particle separation directly impacts blast furnace efficiency, calidad del producto, y presupuestos de mantenimiento. Los desafíos clave incluyen:
Blindness & Atasco: Adhesive coke fines and moisture cause rapid screen mesh blinding, Requiere paradas frecuentes para limpieza manual.. This can result in 1530% downtime on a single line.
Desgaste excesivo & Mantenimiento: The abrasive nature of metallurgical coke accelerates wear on screen decks, ballestas, y mecanismos vibradores, leading to high parts replacement costs and unpredictable failures.
Distribución de tamaño inconsistente: Poor separation allows undersize fines into the blast furnace feed or oversize material into the byproduct stream, disrupting furnace permeability and reducing yield.
Fatiga estructural & Transmisión de vibración: High Gforces needed for effective coke screening can damage support structures and transmit harmful vibrations to adjacent equipment.

Are you evaluating screening solutions that offer higher availability, menor costo por tonelada, and precise grading to protect downstream processes?

2. Descripción general del producto: HeavyDuty Coke Vibration Screens

A Criba vibratoria de coque es de alta capacidad, bruteforce separator designed for the rigorous dry or slightly damp screening of metallurgical coke. Its primary function is to ensure a consistent, specificationgrade feed for blast furnaces while removing undersize coke breeze for other uses.

Flujo de trabajo operativo:
1. Introducción al feed: Runofoven (ROO) coke is uniformly distributed onto the inlet end of the inclined screen deck.
2. Separación vibratoria: An eccentric vibrator assembly imparts a linear or elliptical throwing motion, stratifying material and propelling it along the deck.
3. Segregación por tamaño: Particles smaller than the screen aperture fall through as undersize (brisa de coque), while larger particles travel across the deck as productsized coke.
4. Descargar: Correctly sized coke discharges at the deck end for furnace charging; undersize material is collected separately.

Ámbito de aplicación: Dimensionamiento primario del coque metalúrgico. (typically 25mm80mm fractions), scalping of oven discharge material, and recovery of coke from slag. Not recommended for wet screening or extremely sticky materials without specialized deck technology.
