1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation struggling with persistent bottlenecks, génération d'amendes excessives, et les coûts de maintenance imprévus? Inefficient screening directly impacts your plant’s bottom line through lost product, augmentation de la consommation d’énergie pour les processus en aval, et des temps d'arrêt coûteux pour le remplacement du plateau de criblage. Are you currently facing these challenges?
Aveuglant & Reporter: Moisture and sticky fines blind screen meshes, reducing effective screening area and forcing material to carry over unscreened, contaminating your product fractions.
Usure excessive & Entretien: The abrasive nature of hot coke rapidly degrades standard screen panels and deck components, leading to frequent shutdowns for replacements and high spare parts inventories.
Séparation inefficace: Inconsistent vibration or inadequate screening area results in poor size distribution control, sending offspec material to crushers or battery bunkers, disrupting the entire production chain.
Fatigue structurelle: The intense impact loads from coke discharge can cause premature failure of the screen body and support structures, risking major operational failure.

The right coke vibration screen is not just a separator; it’s a critical asset for throughput stability and product quality control.

2. APERÇU DU PRODUIT

The heavyduty coke vibration screen is a highcapacity, linear motion screening machine engineered for the primary sizing and scalping of metallurgical coke. It is designed to withstand extreme abrasion, impact, and thermal stress in coke handling plants.

Flux de travail opérationnel:
1. Alimentation & Distribution: Hot or cooled coke from a conveyor is discharged onto a robust feed box or plate, distributing the material evenly across the full width of the first screen deck.
2. Primary Stratification & Dimensionnement: The powerful dualvibrator motor drive generates a linear throwing motion. Cette action stratifie le lit de matière, forcing fines downward through the apertures of the upper deck(s) while conveying oversize toward the discharge end.
3. Fraction Separation: Multiple deck levels (typiquement 2 ou 3) with precisely sized screen media (rails, fil tissé, ou panneaux en polyuréthane) separate the coke into defined product streams (par ex., coke de haut fourneau, coca aux noix, brise).
4. Décharge: Sized fractions are discharged via separate chutes for transport to storage bunkers or downstream processes.

Champ d'application & Limites:
Portée: Ideal for primary screening of metallurgical coke after quenching or crushing; scalping of ovenrun coke; separation of coke breeze from larger fractions in byproduct recovery.
Limites: Not designed as a dewatering screen for slurries. Maximum feed temperature is determined by specific component selection (par ex., heatresistant seals, motor isolators). Les matériaux extrêmement collants peuvent nécessiter un prétraitement ou des systèmes de nettoyage de pont spécialisés..

6. SCÉNARIOS D'APPLICATION

Aciérie intégrée – Préparation des aliments pour hauts fourneaux

Défi: A major steel producer experienced rapid blinding of woven wire screens during humid conditions at their BF coke bunker station. This caused significant nut coke fraction carryover into blast furnace feed bins (~12%), disrupting burden permeability and increasing fuel rate.
Solution: Implementation of two largecapacity linear motion screens fitted with nonblinding rod deck media on the upper decks for scalping oversize and openprofile polyurethane panels on lower decks for precise nut/breeze separation.
Résultats: Screening efficiency stabilized above 96%. Carryover was reduced to <3%. The plant reported an annual reduction in fuel rate attributed partly to improved burden control alongside a 65% drop in monthly screenrelated downtime.

Coke Plant – ByProduct Recovery Circuit

Défi: A standalone coking plant needed to maximize recovery of saleable “nut” coke from its crushing circuit but struggled with excessive generation of undersize “breeze” due to aggressive screening action degrading fragile pieces.
Solution:: Installation of a threedeck unit featuring adjustable stroke length via external counterweights on its vibrator motors was selected. This allowed operators finetune intensity based on feed characteristics..
Résultats: By optimizing stroke,,the plant increased yield within target nut size range (+8%) while reducing undersize generation (15%). The gentler handling also extended lowerdeck panel life by approximately 30%.
