1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation plagued by persistent inefficiencies that erode profitability? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the screening phase is a critical bottleneck with direct consequences.

Aveuglant & Reporter: Moisture and fine coke particles blind traditional screens, réduire la zone de contrôle efficace. This leads to undersized material contaminating your product stream or oversized particles damaging downstream crushers, causing unplanned maintenance.
Temps d'arrêt excessif & Entretien: Conventional screens with complex drive mechanisms and numerous bearings require frequent lubrication and are prone to failure. Each hour of unscheduled downtime represents significant lost production revenue.
Séparation inefficace & Incohérence du produit: Inconsistent feed rates or particle distribution result in poor grade control. Are you facing rejections or price penalties due to product not meeting precise size specifications?
Fatigue structurelle & Usure prématurée: The abrasive nature of coke accelerates wear on screen decks and side plates. Premature replacement of these components is a recurring capital expense.
High Energy Consumption for Limited Output: Older screening technology often operates at a fixed, high energy draw regardless of load, leading to inefficient power use per ton of material processed.

La question devient: comment obtenir une fiabilité, consistent coke classification while controlling operational costs and maximizing equipment uptime?

2. APERÇU DU PRODUIT

Le tamis vibrant Custom Coke est un outil robuste, linear motion vibrating screen engineered specifically for the harsh demands of coke sorting and sizing operations. It separates raw or processed coke into two or more precise fractions based on particle size.

Flux de travail opérationnel:
1. Alimentation contrôlée: Coke is fed onto the inlet head of the screen via a conveyor or feeder.
2. Séparation stratifiée: The highGforce linear vibration stratifies the material bed, forcing fines downward through the apertures of the robust screen deck panels.
3. Efficient Conveyance: The linear motion efficiently conveys oversize material along the deck length to the discharge end.
4. Clean Split: Properly sized undersize material passes through the deck, while oversize continues to the designated discharge spout.
5. Fonctionnement continu: The system operates continuously under heavy load with minimal performance degradation.

Champ d'application: Sizing of foundry coke, coke métallurgique (metcoke), coke de pétrole (coke de pétrole), and anodegrade coke in quenching stations, blast furnace feed lines, and calcining plants.

Limites: Non conçu pour coller, highly cohesive materials without pretreatment or specialized deck technology. Maximum efficiency requires controlled, even feed distribution across the full screen width.

6. SCÉNARIOS D'APPLICATION

Metallurgical Coke Plant – Blast Furnace Feed Line

Défi:A major steel producer experienced frequent blinding on circular screens handling quenched coke (~8% moisture). This caused inconsistent sizing feeding their blast furnaces (~25mm cut), leading to irregular furnace operation and increased fuel rate.Solution:The installation of a custom linear motion vibration screen equipped with nonblinding polyurethane tensioned decks designed specifically for damp materials.Résultats: L’efficacité du dépistage s’est stabilisée à >94%. Carryover of fines was reduced by over 80%. Plant engineers reported a measurable improvement in blast furnace consistency within one month.

Calcined Petroleum Coke Facility – Final Product Sizing

Défi:The final sizing stage for anodegrade CPC required an extremely clean separation at multiple cut points (par ex., 4mm +1mm). Existing screens generated excessive dust (1fraction en mm) due to poor stratification.Solution:A custom tripledeck vibration screen was implemented featuring fully enclosed dusttight housings on each deck discharge.Résultats:Product purity improved significantly,directly impacting sales pricing.Dust emissions at the screening station were contained,and recovered ultrafines were captured as a separate,salable product stream,augmenter le rendement global des plantes.
