1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation plagued by persistent bottlenecks and quality control issues? Pour les directeurs d'usine supervisant le criblage du coke, les défis courants ont un impact direct sur le débit et la rentabilité. Une contamination excessive par des fines dans les flux de produits peut entraîner des refus de clients et une perte de revenus.. Le tissu d'écran est souvent aveuglant à cause de la colle, highmoisture coke drastically reduces effective screening area, forcing premature shutdowns for manual cleaning. The constant impact abrasion from bulk coke leads to rapid wear of screen decks and components, generating high replacement part costs and unplanned maintenance windows. Vibration isolation failures transfer destructive forces to support structures, creating longterm integrity concerns and safety risks. How do you maintain specified size fractions consistently while extending equipment service life and maximizing plant uptime? The efficiency of your downstream blast furnace or smelting operation depends on the reliability of this critical separation stage.

2. APERÇU DU PRODUIT

The Coke Vibration Screen is a heavyduty, highamplitude screening machine engineered for the scalping and precise size classification of metallurgical coke, coke de pétrole, et coke de fonderie. Its design prioritizes durability and material throughput in harsh, abrasive environments.

Flux de travail opérationnel:
1. Alimentation & Distribution: Bulk coke is fed onto the robust feed box, which evenly distributes the material across the full width of the primary screen deck.
2. HighEnergy Separation: The exciter drive generates a powerful linear or elliptical motion, aggressively conveying coke along the deck while forcing undersized particles through the screen apertures.
3. Fractional Discharge: Produit correctement dimensionné (surdimensionné) discharges from the deck's end, while fines (sous-dimensionné) pass through to a lower collection chute or subsequent deck for further grading.

Champ d'application: Calibrage primaire du coke déchargé du four, suppression de la brise (amendes) from blast furnace feed, classification of recirculated coke in sinter plants, et applications de dépoussiérage.

Limites: Not designed for ultrafine screening (8%) may require predrying or heated deck options.

3. CARACTÉRISTIQUES PRINCIPALES
