1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Votre opération de manutention de coke est-elle en proie à des goulots d'étranglement persistants, génération d'amendes excessives, et les coûts de maintenance imprévus? Pour les directeurs d'usine supervisant le criblage du coke, les défis courants ont un impact direct sur les résultats:
Aveuglant & Temps d'arrêt: Moisture and sticky fines blind screen decks, halting production for manual cleaning. Each hour of downtime can cost thousands in lost throughput.
Séparation inefficace: Inconsistent particle size distribution leads to underperforming blast furnaces or rejected product from battery clients.
Charge de maintenance élevée: Conventional screens with numerous moving parts and intense vibration require frequent bearing changes, spring replacements, and structural welds.
Génération d’amendes excessives: Aggressive, inefficient screening action breaks down coke, creating excess fines that degrade product value and create handling issues.
Inefficacité énergétique: Overpowered drives running constantly to overcome blinding waste significant electrical power.

Are you searching for a screening solution that delivers consistent cut points, maximise la disponibilité, et réduit votre coût total de possession?

2. APERÇU DU PRODUIT

The Coke Vibration Screen is a highcapacity, heavyduty screening machine engineered for the precise separation of metallurgical coke and coke breeze in demanding processing environments. Its core function is to reliably size coke into specific fractions (par ex., coke de haut fourneau, coca aux noix) tout en supprimant les amendes.

Flux de travail opérationnel:
1. Alimentation & Distribution: Runofoven or crushed coke is fed onto the screen’s robust feed box, qui répartit uniformément le matériau sur toute la largeur du pont de criblage.
2. Séparation stratifiée: A dualmass vibratory system drives a linear or elliptical motion, matériau de stratification. Larger particles convey across the deck surface while smaller particles pass through the screen apertures.
3. Product Stream Segregation: Separated fractions are discharged via dedicated chutes—typically oversized material (overs), produit conforme aux spécifications (médiums), et des amendes (sous)—for routing to storage or downstream processes.

Champ d'application: Criblage primaire et secondaire du coke métallurgique, séparation des brises de coke, sinter feed preparation, and prescreening for crushing circuits.

Limites: Non conçu pour coller, nonfreeflowing materials without specialized deck technology. La taille maximale des grumeaux est limitée par les spécifications de conception de la goulotte d'alimentation et du plateau..
