Grossistes de tamis vibrants pour coke de luxe: HighCapacity Screening Solutions for Industrial Coke Processing

The Cost of Inefficient Coke Screening

Your plant loses an estimated $12,000–$18,000 per month per screening line when coke fines contaminate your premium product. Inconsistent particle size distribution causes downstream processing delays, burner nozzle clogging, and customer rejection rates exceeding 8% in some metallurgical applications. Are your current screens handling the abrasive nature of petroleum coke without excessive blinding or structural fatigue? Do you face 6–10 unscheduled maintenance shutdowns annually due to screen deck failure under hightonnage loads? Can your existing equipment maintain <2% oversize contamination when processing 200+ tons per hour of calcined coke?

Présentation du produit: Écran vibrant pour coke robuste

Le Écran vibrant de luxe pour coke is a linearmotion, dualshaft vibratory classifier engineered specifically for petroleum coke, coke métallurgique, and calcined coke fractions from 3mm to 80mm. This equipment integrates into existing conveyortostorage or conveyortoprocess lines.

Flux de travail opérationnel:
1. Présentation du flux: Material enters via chute at 150–350 TPH, distributed across full deck width by a segmented feed box
2. Stratification: Dual eccentric shafts generate 4.2G–5.8G linear acceleration, separating fines (<6mm) through the bottom deck within 1.5 secondes
3. MidSize Classification: Middle deck (8–25mm apertures) isolates product fractions for direct loading or grinding feed
4. Oversize Rejection: Top deck (+50mm) diverts large coke pieces to crusher recirculation or rejection conveyor
5. Décharge: Three independent outlets feed downstream equipment with <1% crosscontamination between fractions

Champ d'application: Suitable for green coke, calcined coke, and foundry coke at temperatures up to 120°C. Not recommended for wet coke exceeding 12% moisture content without optional heated deck systems.

Limites: Maximum feed lump size of 120mm; requires 8–12m clearance height for installation; not designed for sticky or tarcontaminated coke without antiblinding modifications.

Scénarios d'application

Calcined Coke Storage and Blending

Défi: A Gulf Coast calciner was experiencing 7% fines generation during screening, causing blending inconsistencies for anodegrade coke. Customer rejection rate reached 12% over six months. Solution: Installed two LCVS2472 units with 6mm and 25mm polyurethane decks, replacing existing 2.4m x 6.0m wire cloth screens. Résultats: Fines contamination reduced to 1.8%; blending accuracy improved to ±0.5% of target specification; customer rejections dropped to 1.2% dans les trois mois. Annual savings from reduced reprocessing: $240,000.

Metallurgical Coke Processing for Foundries

Défi: A midwest foundry coke producer needed to separate 8mm–25mm cupolagrade coke from 50mm blast furnace material while maintaining <2% fines in the product. Existing screen deck lasted only 6 months due to coke abrasion. Solution: Deployed LCVS3060 with AR400 top deck (50ouvertures en mm) and polyurethane middle deck (8mm slotted apertures). Résultats: Deck life extended to 22 mois; product fines content stabilized at 1.5%; le débit est passé de 220 TPH à 295 TPH. Maintenance costs reduced by $18,000 annuellement.

Green Coke Drying and Classification

Défi: A Texas petroleum refinery needed to screen 8% moisture green coke at 180 TPH while preventing deck blinding. Previous screens required manual cleaning every 4 heures. Solution: Installed LCVS1860 with heated polyurethane panels (60°C surface temperature) and ball tray assemblies. Résultats: Blinding reduced to 3% du temps de fonctionnement; manual cleaning eliminated; débit maintenu à 175 TPH even at 10% humidité. Energy cost increase of $0.02/ton offset by $5,200/month labor savings.

Foire aux questions

Q: Can the Luxury Coke Vibration Screen handle both green and calcined coke without modification?
UN: Oui, with the adjustable deck angle feature (12°–22°) and VFDcontrolled vibration frequency, the same unit processes both materials. For green coke above 8% humidité, we recommend the heated deck option to prevent blinding.

Q: What is the typical installation timeline from order to operation?
UN: Standard lead time is 10–12 weeks for fabrication, plus 3–5 days for installation and commissioning. The Pro Service Package includes onsite installation supervision and operator training within that timeline.

Q: How does this screen compare to highfrequency vibrating screens for fine coke classification?
UN: For cut points above 3mm, the linearmotion design provides 12–15% higher throughput than highfrequency screens. For sub3mm classification, highfrequency screens may be more appropriate. We can provide testing data for your specific particle size distribution.

Q: What warranty coverage is provided for the screen decks under abrasive coke service?
UN: AR400 steel decks carry a 12month warranty against perforation. Polyurethane panels carry a 24month warranty against wearthrough. Both exclude damage from foreign objects or improper operation.

Q: Can this equipment integrate with existing PLC and SCADA systems?
UN: Oui. The standard control package includes Modbus RTU communication. Optional Profibus, Ethernet/IP, or OPCUA modules are available. We provide full integration documentation and remote commissioning support.

Q: What is the expected annual maintenance cost for a single LCVS2472 unit?
UN: Basé sur 6,000 heures de fonctionnement par an, estimated maintenance costs are $14,000–$18,000 annually, including panel replacements, lubrification des roulements, and vibration analysis. This represents a 40–50% reduction compared to wire cloth screens in similar service.

Q: Do you offer performance guarantees for throughput and screening efficiency?
UN: Oui. With the Elite Service Package, we guarantee 92% minimum screening efficiency at the specified cut point and 95% of rated throughput. Performance is verified during commissioning and at annual inspections.
