1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation struggling with persistent bottlenecks and hidden costs? The screening stage is often a critical failure point, directly impacting downstream process stability and final product revenue. Les défis courants incluent:

Excessive Fines Generation: Inefficient or aggressive screening action degrades premium coke into lowvalue fines, eroding profit margins with every ton processed.
Temps d'arrêt imprévus: Screen deck blinding and premature wear on components like screen cloths lead to frequent, costly stoppages for maintenance and cleaning.
Inconsistent Product Grading: Variability in cutpoint accuracy results in offspec material, causing rejections from blast furnace operators or requiring costly rehandling.
Coûts opérationnels élevés: Constant component replacement, high energy consumption from inefficient drives, and laborintensive manual clearing directly increase your cost per ton.

Are you seeking a screening solution that prioritizes product integrity, maximizes uptime, and delivers a measurable return on investment? The reliability of your entire coke handling line depends on the performance of this single unit.

2. APERÇU DU PRODUIT

This content details our engineered Écran vibrant de coke solutions, manufactured under contract to the highest specifications for demanding industrial applications. This equipment is a heavyduty linear or elliptical motion vibrating screen designed for the precise sizing and scalping of metallurgical coke and similar carbon products.

Flux de travail opérationnel:
1. Présentation du flux: Sized coke from the crusher or coke oven is uniformly fed onto the screen’s inlet section via a conveyor or chute.
2. Stratification & Séparation: HighGforce vibration stratifies the material bed. Smaller particles pass through the precisely sized apertures of the screen deck(s), while onsize overs continue across the deck surface.
3. Décharge du produit: Correctly sized unders material collects in a hopper below, while overs discharge at the screen’s end, ensuring clean separation into two or more product streams.

Champ d'application: Primary sizing (scalper) and final grading of metallurgical coke, recrusher feed preparation, and dedusting operations in coke plants, aciéries, and carbon processing facilities.

Principales limites: Not designed for sticky materials without specialized deck technology; maximum feed size is constrained by screen design parameters; performance is contingent on correct installation and feed rate control.

3. CARACTÉRISTIQUES PRINCIPALES

Our Coke Vibration Screen design incorporates features targeting operational longevity and grading precision.
