1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Every ton of calcined or metallurgical coke you process carries a hidden cost: contamination. In highvalue coke applications—whether for anode production, sidérurgie, or specialty chemicals—oversized lumps block downstream conveyors, while fines (<6mm) reduce furnace efficiency and degrade product value. Industry data indicates that poorly screened coke can result in 35% yield loss per batch, translating to $15,000–$25,000 in lost revenue per 10,000ton shipment. Downtime from screen blinding or mechanical failure adds another 8–12 hours of unplanned maintenance monthly.

Are your current screens handling the abrasive, hightemperature nature of coke without sacrificing throughput? Can your equipment maintain consistent particle size distribution (PSD) under 200°C material feed? For importers supplying luxurygrade coke to premium markets, these are not optional questions—they are contractual requirements.

2. APERÇU DU PRODUIT

Type d'équipement: Heavyduty linear motion vibration screen, specifically engineered for calcined petroleum coke (CPC) and metallurgical coke (metcoke) classification.

Flux de travail opérationnel:
1. Entrée d'alimentation: Coke enters via a chute with wearresistant lining, distributing material across the full screen width.
2. Vibration Generation: Dual eccentric shafts produce linear motion at 750–1,000 RPM, conveying material forward while stratifying particles.
3. Séparation multi-étages: Two or three screen decks (polyurethane or wire mesh) separate material into coarse (+25mm), taille moyenne (6–25mm), et des amendes (6mm) fractions.
4. Décharge: Each fraction exits through dedicated spouts, with optional dust collection ports.
5. Oversize Recycle: Coarse material can be routed to a crusher for rescreening.

Champ d'application: Suitable for dry coke with moisture content below 8%, feed temperatures up to 250°C, and particle sizes from 0.5mm to 80mm.

Limites: Not designed for wet or sticky coke (humidité >12% causes blinding). Requires periodic mesh replacement every 6–12 months depending on abrasion.

8. FAQ

Q: Can this screen handle green coke (raw petroleum coke) with 10–15% moisture?
UN: Non. Green coke with moisture above 8% will cause rapid blinding of polyurethane panels. For wet coke, we recommend a separate dewatering screen or drying step before this unit.

Q: What is the typical lead time for importers?
UN: Standard units ship within 8–10 weeks from order confirmation. Custom configurations require 12–16 weeks, y compris l'examen technique.

Q: How does the screen perform with coke that has high ash content (12–15%)?
UN: Field data shows screening efficiency drops by 3–5% with highash coke due to increased fines generation. We recommend using 8mm amplitude and 950 RPM frequency to maintain 92%+ efficacité.

Q: What warranty is included with the equipment?
UN: 24 mois à compter de la mise en service ou 30 mois à compter de l'expédition, selon la première éventualité. Covers manufacturing defects in structural components and drive system. Screen panels are consumables and warrantied for 6 mois.

Q: Can this screen be integrated into an existing conveyor system without major modifications?
UN: Oui. The unit includes adjustable mounting feet and standard flange connections (DN200 inlet, DN150 outlets). Most installations require only minor chute modifications, typically completed in 2–3 days.

Q: What is the expected annual maintenance cost for a 2deck unit?
UN: Basé sur 4,000 heures de fonctionnement par an, maintenance costs average $6,000–$8,000 annually, including panel replacement (every 12–18 months), lubrification des roulements, and spring inspection.

Q: Do you provide installation supervision for importers?
UN: Oui. Onsite supervision is available at $1,200/day plus travel expenses, typically requiring 5–7 days for full commissioning and operator training.
