1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Votre opération de criblage de coke est-elle en proie à des problèmes persistants, des inefficacités coûteuses? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the challenges of screening metallurgical coke directly impact throughput, qualité du produit, et la rentabilité nette. Les points douloureux courants incluent:

Génération d’amendes excessives: Aggressive or poorly tuned vibration can degrade premium coke into undersized fines, reducing valuable product yield and creating excess waste material.
Aveuglant & Reporter: Sticky coke breeze and moisture cause screen mesh blinding, while insufficient vibration leads to material carryover. Both scenarios force frequent stoppages for manual cleaning and result in inconsistent size fractions.
Temps d'arrêt pour maintenance élevé: Constant, heavyduty operation leads to premature failure of screen decks, ressorts, and vibrator motors. Unplanned downtime for repairs disrupts blast furnace feed schedules.
Inefficient Capacity Management: A singlescreen setup cannot adapt to varying feed rates or different size specifications, creating bottlenecks in highvolume operations.

Are you facing rising operational costs due to screen maintenance and product loss? Is your current equipment failing to deliver consistent grade separation under full load? The solution requires a purposeengineered approach to material handling.

2. APERÇU DU PRODUIT

The Coke Vibration Screen is a heavyduty industrial screening machine designed for the precise separation of metallurgical coke into defined size fractions (par ex., coke de haut fourneau, coca aux noix). It operates on the principle of applied vibration to stratify and convey material across a screening surface.

Flux de travail opérationnel:
1. Alimentation contrôlée: Sized coke from the crusher is evenly distributed onto the inlet end of the vibrating screen deck via a feed box or conveyor.
2. Stratification & Séparation: Haute fréquence, lowamplitude vibration fluidizes the bed of material. Smaller particles sift through the apertures of the screen cloth (panneau), while oversized particles travel across the deck surface.
3. Décharge efficace: Correctly sized material (traversées) discharges from a lower outlet chute. Matériau surdimensionné (overs) travels along the deck length and discharges from the end, directed to downstream processes.

Champ d'application: Primary and secondary sizing of metallurgical coke in coke plants, aciéries, and ferroalloy facilities. Convient au criblage de coke chaud ou froid.

Limites: Not designed for wet screening or slurries without significant modification. Maximum lump size is constrained by feed chute and deck design specifications.
