1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke processing operation struggling with persistent bottlenecks and escalating costs at the screening stage? Les défis courants rencontrés avec les écrans conventionnels ont un impact direct sur vos résultats. Vivez-vous:
Aveuglant & Temps d'arrêt: L'humidité et les fines particules de coke obstruent les plateaux de criblage, nécessitant des arrêts fréquents pour un nettoyage manuel, coûtant des centaines d'heures de production par an.
Inconsistent Grading: Poor separation leads to offspec product (undersize in metallurgical coke, oversize in breeze), resulting in product rejection and revenue loss.
Entretien excessif: The abrasive nature of coke accelerates wear on screen panels and components, driving up spare parts costs and labor for replacements.
Consommation d'énergie élevée: Inefficient vibration mechanisms and heavyduty designs lead to disproportionately high power usage per ton of material processed.
Fatigue structurelle: Constante, highimpact loads from bulk coke can cause weld cracks and structural failures in the screen body, risking major unplanned downtime.

La question centrale pour les directeurs d’usine est claire: comment pouvez-vous obtenir un, continuous coke classification with lower operational expenditure and maximized equipment lifespan?

2. APERÇU DU PRODUIT

Le tamis vibrant China Coke est un outil robuste, linear motion vibrating screen engineered specifically for the highvolume sizing and scalping of metallurgical coke, coke de pétrole, et coke de fonderie. It is designed to handle the unique abrasiveness, densité, and size ranges of bulk coke in processing plants.

Flux de travail opérationnel:
1. Alimentation & Distribution: Bulk coke from crushers or ovens is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. Stratification efficace & Séparation: Dual vibrator motors generate a linear throwing motion, stratifying material rapidly. Coke particles smaller than the screen panel apertures pass through as undersize product.
3. Décharge: Correctly sized oversize material travels along the deck length and discharges at the end, while undersize material collects in a hopper below.

Champ d'application: Dimensionnement primaire (scalper) de coke runofoven, secondary screening of crushed coke (par ex., 2540coke de haut fourneau mm), dépoussiérage (coke breeze removal), and dewatering applications.

Limites: Not designed for extremely sticky materials without specialized deck treatments. Maximum lump size is typically limited to 200mm; alternative solutions are required for larger primary runofmine scalping.
