1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are your coke screening operations plagued by persistent inefficiencies that directly impact your bottom line? Les défis courants incluent:

Temps d'arrêt excessif: Frequent screen cloth blinding and premature wear from abrasive coke fines, leading to unscheduled maintenance stops and lost production hours.
Classement des produits incohérent: Inefficient separation resulting in offspec material—oversize particles contaminating the nut coke fraction or excessive fines in the blast furnace feedstock—compromising downstream process efficiency.
Coûts opérationnels élevés: Constant replacement of screen decks, excessive energy consumption from inefficient vibration mechanisms, and high labor costs for manual clearing and maintenance.
Problèmes d’intégrité structurelle: Vibration transmission to support structures causing fatigue cracks and foundation issues, creating longterm plant safety and capital expenditure risks.
Émission de poussière & Déversement: Poor sealing and excessive vibration exacerbate housekeeping issues, creating environmental control challenges and product loss.

Is your current screening solution a source of recurring cost and reliability headaches? Que serait un 2030% reduction in maintenance intervals and a 15% improvement in screening efficiency mean for your annual operational budget?

2. APERÇU DU PRODUIT

The Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise size classification of metallurgical coke. It separates crushed coke into defined fractions—such as blast furnace coke, coca aux noix, and breeze—critical for optimal furnace operation.

Flux de travail opérationnel:
1. Présentation du flux: Crushed coke is uniformly distributed onto the feed box of the inclined screen deck(s).
2. Séparation vibratoire: A highefficiency vibrator assembly imparts a linear or elliptical motion, stratifying material and propelling it across the screening surface.
3. ​​SizeBased Stratification: Particles smaller than the screen aperture fall through as undersize, while larger particles travel across the deck to discharge as oversize.
4. Décharge de fraction: Separated material streams are discharged via dedicated chutes into designated collection hoppers or conveyors for further processing or shipment.

Champ d'application & Limites:
Portée: Ideal for primary sizing of hot or cold metallurgical coke in coke plants, aciéries, et terminaux de manutention de vrac. Effective for capacities ranging from 200 à 1500+ tonnes par heure.
Limites: Non conçu pour les matériaux collants sans prétraitement (par ex., preheating). Performance is contingent on proper feed rate control and consistent moisture content management.
