1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling and classification process a source of chronic downtime and profit erosion? For plant managers overseeing coke production for blast furnaces or anode baking, inefficient screening directly impacts product quality and operational cost. Les défis courants incluent:

Aveuglant & Reporter: Bien, les particules de coke humides adhèrent aux plateaux de criblage, blinding apertures and forcing oversized material into the product stream, compromising metallurgical grade specifications.
Excessive Deck Wear & Entretien: The abrasive nature of metallurgical coke accelerates wear on screen panels and components, conduisant à de fréquents, costly replacements and unplanned shutdowns.
Inconsistent Feed Rate Handling: Fluctuations in feed from upstream crushers or conveyors can overwhelm standard screens, causing stratification failure and reducing screening efficiency.
Fatigue structurelle & Isolation des vibrations: Highcycle operations transfer damaging vibrations to support structures, increasing longterm maintenance costs for the entire screening station.

Are you facing rising maintenance costs, inconsistent product quality, and throughput bottlenecks? The right premium coke vibration screen is not just a piece of equipment; it is a critical process guarantee.

2. APERÇU DU PRODUIT

A premium coke vibration screen is a highcapacity, heavyduty screening machine designed for the precise size separation of metallurgical (rencontré) coke and petroleum (animal de compagnie) coke. Conçu pour 24/7 operation in harsh, abrasive environments, it ensures consistent product sizing critical for blast furnace efficiency and carbon anode production.

Flux de travail opérationnel:
1. Alimentation contrôlée: Coke feedstock is delivered via conveyor onto the screen’s feed box, which evenly distributes material across the full width of the first deck.
2. Stratification & Séparation: Haute intensité, linear or elliptical vibration forces material to stratify. Les amendes passent par les ouvertures du pont supérieur; middlings are conveyed to lower decks for further separation; oversize is discharged at the end of the deck.
3. Décharge: Correctly sized fractions are discharged through dedicated chutes into separate product streams (par ex., coke de noix de haut fourneau, brise) for downstream processing or shipment.

Champ d'application: Calibrage primaire et secondaire du coke métallurgique (coke de haut fourneau), coke de pétrole, recarburateurs, and other abrasive carbon materials. Convient aussi bien aux nouvelles installations qu'aux mises à niveau.

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

6. SCÉNARIOS D'APPLICATION

Integrated Steel Plant – Blast Furnace Coke Sizing

Challenge A major steel producer faced frequent blinding during humid months on their primary coke screens. This caused oversized material (>80mm) contaminating the nut coke (2580mm) fraction supplied to their blast furnaces,
reducing permeability and increasing fuel rate.
Solution Installation of two widebody premium coke vibration screens featuring multilayer antiblinding polyurethane decks on all three sizing stages.
Results Screening efficiency stabilized at 94%. Oversize contamination in nut coke fraction fell below specification (<2%). Annual maintenance hours decreased by approximately65%, primarily due to elimination of daily manual deck rapping.

Petroleum Coke Calcining Plant – Anode Grade Coke

Challenge A calciner needed precise separation of calcined petcoke into multiple fractions (1mm,+4mm, etc.)for anode paste formulation.Severe abrasion wore out standard stainless steel mesh decks every8 weeks,causing variable particle size distribution that affected anode quality.
Solution Retrofit of existing screen structures with premium modular tensioned decks using proprietary abrasionresistant rubber compound panels configuredfor four fractions.
Results Deck life extendedto7 months per set.Particle size distribution consistency improved significantly(standard deviation reducedby40%), enhancing downstream anode homogeneity.Return on investment achievedin under11 months through reduced part costsand avoided quality penalties.
