1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

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%.
Colmatage fréquent de l’écran & Temps d'arrêt: Collant, moist coke can rapidly blind screen decks, nécessitant des arrêts fréquents pour un nettoyage manuel. Unplanned downtime of 23 hours per event directly cuts production throughput.
Entretien élevé & Coûts de remplacement: Standard screens with inferior materials or unbalanced vibration mechanisms suffer from accelerated wear on decks, ressorts, et excitateurs, entraînant une consommation élevée de pièces de rechange et des coûts de main d’œuvre élevés.
Débit incohérent: 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, maximise la disponibilité, et offre un retour sur investissement mesurable? The right industrialgrade coke vibration screen is a critical component for cost control.

2. APERÇU DU PRODUIT

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 (par ex., coke de noix de haut fourneau, brise).

Flux de travail opérationnel:
1. Alimentation contrôlée: 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. Stratification efficace & Séparation: A dualshaft exciter generates a linear throwing motion, matériau de stratification. Oversize particles travel across the deck surface while undersize material passes through the screen apertures.
3. Décharge: Separated fractions are discharged via distinct chutes—oversize to crusher or product stockpile, onsize to product conveyor, et des amendes (brise) to a dedicated collection system.

Champ d'application: Primary sizing of hot or cold metallurgical coke in coke plants, aciéries, et terminaux de manutention de vrac. Ideal for capacities from 100 à 1500+ TPH.

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