1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke screening operation plagued by persistent bottlenecks that erode profitability? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the challenges of screening metallurgical coke are acute. Excessive fines generation due to aggressive vibration directly impacts blast furnace efficiency and product revenue. Changements fréquents de tissu d'écran, driven by premature wear from abrasive coke, cause significant production downtime and high consumable costs. Distribution granulométrique incohérente, resulting from inefficient separation or blinding, compromises downstream process stability. De plus, structural failures in the screen body or deck from highcycle fatigue lead to catastrophic unplanned shutdowns. Are you facing rising maintenance costs, disponibilité imprévisible, and a constant battle to meet stringent size specifications? The core of these issues often lies in the design and durability of your écran vibrant de coke.

2. APERÇU DU PRODUIT

This product is a heavyduty linear motion vibrating screen engineered explicitly for the sizing and scalping of metallurgical coke. Sa conception privilégie la durabilité, precise separation, and highcapacity throughput in demanding coke handling plants.

Flux de travail opérationnel:
1. Alimentation & Distribution: Coke feedstock is evenly distributed across the full width of the screen inlet via an integrated feed box.
2. Séparation stratifiée: Two counterrotating vibratory motors generate a linear throwing motion, stratifying material across multiple deck levels equipped with defined aperture screen panels.
3. Classement des tailles: Oversize material travels across the top deck for discharge; middlings are separated on subsequent decks; correctly sized product passes through the apertures.
4. Décharge: Separated fractions are discharged via dedicated chutes for routing to blast furnace bins, crusher circuits, or product stockpiles.

Champ d'application: Calibrage primaire du coke déchargé du four, coke breeze removal, prescreening before crushing, and final product grading.
Limites: Not designed for wet screening applications or for materials with extreme temperature fluctuations beyond specified ranges.

3. CARACTÉRISTIQUES PRINCIPALES

Système de terrasse modulaire | Base technique: Les boules, sidetensioned panel frames with independent clamping. | Avantage opérationnel: Enables singledeck changeouts in under two hours versus full deck replacement; allows use of varied panel materials (caoutchouc, polyuréthane, fil tissé) per deck level based on wear profile. | Impact sur le retour sur investissement: Reduces downtime for screen media maintenance by up to 60% and lowers consumable costs by targeting material grade where needed.

Entraînement par moteur à double contre-rotation | Base technique: Deux moteurs vibrants synchronisés générant un vecteur force linéaire; nonsynchronous operation causes immediate selfcancellation of vibration. | Avantage opérationnel: Provides consistent material travel speed and throw pattern for reliable sizing; inherent safety feature prevents structural damage if one motor fails. | Impact sur le retour sur investissement: Ensures stable product quality (size consistency >98%) and eliminates risk of catastrophic drive failure leading to extended downtime.

Construction boulonnée Huck & Reinforced Deck Frames | Base technique: Highstrength alloy steel side plates joined via Huck fastening system; internal cross members are fully welded to side plates before stressrelieving. | Avantage opérationnel: Crée un rigide, monolithic frame resistant to cracking from cyclic stress; dramatically extends service life in 24/7 opération. | Impact sur le retour sur investissement: Les données de terrain montrent un >40% improvement in structural lifespan compared to traditional bolted frames, reporter les dépenses d'investissement importantes.

Moteurs vibrants encapsulés dans la poussière | Base technique: IP66rated protection with labyrinth seals and positivepressure dust purge ports (facultatif). | Avantage opérationnel: Protects motor bearings from pervasive coke dust ingress, the leading cause of bearing seizure and motor failure. | Impact sur le retour sur investissement: Extends motor service life by an average of 30%, réduisant les stocks de pièces de rechange et les coûts de main-d'œuvre de remplacement.

Adjustable Vibration Amplitude | Base technique: External weight adjustment on motor shafts without disassembly.| Avantage opérationnel: Operators can finetune the throw amplitude to match specific feed rates or coke characteristics (par ex., collant vs. freeflowing), optimiser l'efficacité.| Impact sur le retour sur investissement: Maximizes screening efficiency across varying feed conditions, preventing lost capacity or misdirected product that impacts furnace performance.
