1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation facing persistent bottlenecks and rising costs? L’étape de sélection est souvent un point d’échec critique, directly impacting downstream processing and overall plant profitability. Les défis courants incluent:

Aveuglant & Reporter: Ponts de criblage aveugles pour l'humidité et les fines particules de coke, tandis que les matériaux surdimensionnés sont transportés dans les silos de produits finis. Il en résulte un produit hors spécifications, refus des clients, and costly rehandling.
Temps d'arrêt excessif pour la maintenance: Défaillances fréquentes des roulements, remplacements de tissu d'écran, and structural weld cracks demand constant attention from your maintenance crew, stealing valuable production hours.
Consommation d'énergie élevée & Transmission des vibrations: Inefficient vibratory mechanisms consume excess power and transmit destructive forces to the support structure, leading to accelerated wear on the entire screening station.
Séparation de niveaux incohérente: An inability to maintain precise cut points leads to product contamination, reducing the market value of your metallurgical or foundry coke.

Are you evaluating how a purposeengineered Écran vibrant de coke can reduce your total cost of ownership, increase screening availability above 95%, and ensure consistent product quality?

2. APERÇU DU PRODUIT

UN Écran vibrant de coke est une grande capacité, heavyduty screening machine designed for the scalping, dimensionnement, and dedusting of hot or cold metallurgical coke in battery, trempe, and sorting plants. Its core function is to separate coke feedstock into precise size fractions (par ex., coke de haut fourneau, coca aux noix, brise) tout en supprimant les amendes.

Flux de travail opérationnel:
1. Bulk coke from the quench car or feed conveyor is discharged onto the screen's robust feed box.
2. Highmagnitude, linear or elliptical vibratory motion stratifies the material bed and propels it across the multideck screening surfaces.
3. Undersize material passes through sequentially smaller apertures on each deck.
4. Correctly sized fractions discharge at designated outlets for conveyor transfer to storage bins or loading stations.
5. Matière surdimensionnée (par ex., +80mm) exits at the screen's discharge end for potential crushing or recirculation.

Champ d'application: Calibrage primaire et secondaire du coke métallurgique, récupération de brise de coke, prescreening before crushing. Not suitable for sticky materials without specialized deck technology or as a replacement for a crusher.
