1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Votre opération de manutention de coke est-elle en proie à une qualité de produit incohérente, génération d'amendes excessives, and unplanned maintenance halts? Pour les directeurs d'usine supervisant le criblage du coke, common challenges directly impact profitability and throughput. Vivez-vous:

Aveuglant & Reporter: Moisture or sticky fines blinding screen decks, causing product contamination and forcing premature shutdowns for manual cleaning.
Temps d'arrêt excessif: Frequent bearing failures or structural fatigue on vibrating screens leading to 2040 hours of unscheduled downtime annually for repairs and parts replacement.
Coûts de maintenance élevés: The abrasive nature of coke accelerating wear on screen panels, ponts, et excitateurs, resulting in high consumable costs and labor for changeouts.
Inefficient Sizing: Inconsistent feed rates or improper vibration dynamics producing offspec material, leading to customer rejections or reprocessing costs.

La question centrale est: comment pouvez-vous obtenir des résultats précis, reliable coke classification while maximizing equipment uptime and minimizing total cost of ownership? The answer lies in selecting a purposeengineered Écran vibrant de coke.

2. APERÇU DU PRODUIT

UN Écran vibrant de coke is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions—typically nut coke, brise, and lump coke—after the quenching process. Its robust construction handles highly abrasive materials while resisting corrosion from residual moisture.

Flux de travail opérationnel:
1. Alimentation contrôlée: Quenched coke is conveyed onto the screen’s feed box, distributing material evenly across the full width of the top deck.
2. HighIntensity Separation: A dualvibrator mechanism imparts a linear or elliptical motion, stratifying material and propelling particles across the screen cloths.
3. Precise Sizing: Oversize material travels across the top deck apertures, while correctly sized particles pass through to lower decks for further fractionation.
4. Décharge & Transport: Separated fractions discharge via dedicated chutes onto designated conveyors for stockpiling or direct feed to blast furnaces.

Champ d'application & Limites:
Portée: Ideal for sinter plants, systèmes de chargement de hauts fourneaux, and foundry operations requiring strict size control (par ex., 2540mm nut coke). Effective for hot or cold coke screening postquenching.
Limites: Non conçu pour les processus de criblage humide ou pour remplacer les cribles scalpeurs manipulant des dimensions extrêmement grandes. (+300mm) feedstock without prior crushing. Performance is contingent on proper installation on a structurally adequate support base.
