1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation struggling with inefficient screening that impacts downstream quality and profitability? Common challenges with inadequate coke vibration screens include:

Excessive Fines Contamination: Inconsistent particle separation allows undersized coke fines to enter blast furnace feed, disrupting burden permeability and increasing fuel rates. This can increase operational costs by 35%.
Obstrucción frecuente de la pantalla & Falta del tiempo: Pegajoso, moist coke can rapidly blind screen decks, Requiere paradas frecuentes para limpieza manual.. Unplanned downtime of 23 hours per event directly cuts production throughput.
Alto mantenimiento & Costos de reemplazo: Standard screens with inferior materials or unbalanced vibration mechanisms suffer from accelerated wear on decks, ballestas, y excitadores, leading to high spare part consumption and labor costs.
Rendimiento inconsistente: Underpowered or poorly designed screens cannot handle variable feed rates, creating bottlenecks in your material handling circuit and limiting plant capacity.

Are you searching for a robust screening solution that delivers consistent coke classification, maximiza el tiempo de actividad, y proporciona un retorno de la inversión medible? The right industrialgrade coke vibration screen is a critical component for cost control.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product line comprises heavyduty linear motion vibrating screens engineered specifically for the dry screening of metallurgical coke. Designed to handle abrasive materials and highimpact loads at transfer points, these units ensure precise separation of coke into defined size fractions (p.ej., coque de nuez de alto horno, brisa).

Flujo de trabajo operativo:
1. Alimentación controlada: Coke is discharged from a conveyor onto the screen’s feed box, which distributes material evenly across the full width of the screening deck.
2. Estratificación eficiente & Separación: A dualshaft exciter generates a linear throwing motion, material estratificante. Oversize particles travel across the deck surface while undersize material passes through the screen apertures.
3. Descargar: Separated fractions are discharged via distinct chutes—oversize to crusher or product stockpile, onsize to product conveyor, y multas (brisa) to a dedicated collection system.

Ámbito de aplicación: Primary sizing of hot or cold metallurgical coke in coke plants, acerías, y terminales de manipulación de graneles. Ideal for capacities from 100 a 1500+ TPH.

Limitaciones: Not designed for wet screening applications or for materials with extreme adhesive properties without specialized deck treatments.
