1. PAINPOINT DRIVEN OPENING

Are you managing a coke processing or steel plant operation where screening efficiency directly impacts your bottom line? The challenges with traditional coke vibration screens are welldocumented: persistent blinding of screen decks leading to rapid capacity loss, excessive structural fatigue from highimpact coke loads causing premature failure, and uncontrolled dust emissions creating environmental and housekeeping issues. Each hour of unplanned downtime for screen maintenance or deck replacement translates to significant lost production tonnage. How do you maintain consistent product sizing for blast furnace feed? What operational changes can reduce your total cost of ownership for screening equipment? Is there a solution that improves screening accuracy while extending service intervals?

2. PRODUCT OVERVIEW

The Luxury Coke Vibration Screen is a heavyduty, highcapacity linear motion screening machine engineered specifically for the sizing and scalping of metallurgical coke and similar abrasive, highdensity materials. Its operational workflow is designed for maximum reliability: (1) Feed material is evenly distributed across the full width of the screen deck via an integrated feed box. (2) A dualvibrator drive system generates a linear throwing motion, efficiently conveying and stratifying material while preventing plugging. (3) Precisely sized coke particles pass through the configured screen media, while oversize material is discharged at the end of the deck. This equipment is optimal for primary sizing, dedusting, and scalpandscreen applications in coke plants, steel mills, and foundries. It is not designed for fine screening (< 3mm) or for highly sticky materials without specialized deck treatments.

3. CORE FEATURES

HeavyDuty Deck Support System | Technical Basis: Multipoint rubber buffer isolators combined with reinforced crossmembers | Operational Benefit: Absorbs direct impact energy, reducing stress transfer to the main frame and minimizing deck panel fatigue | ROI Impact: Extends deck life by up to 40%, reducing spare parts inventory and changeout labor costs.

Advanced AntiBlinding Technology | Technical Basis: Independently suspended, highfrequency secondary vibration system attached to screen cloth | Operational Benefit: Dislodges nearsize particles trapped in apertures, maintaining open screen area and consistent throughput | ROI Impact: Sustains design capacity, eliminating frequent shutdowns for manual cleaning and improving product consistency.

Enclosed DustTight Design | Technical Basis: Fulllength rubber sealing strips between side plates, decks, and dust hoods with negative pressure connections | Operational Benefit: Contains airborne coke fines at transfer points, improving plant air quality and recoverable product yield | ROI Impact: Reduces dust collection loadhousekeeping costsand mitigates compliance risks.

Dual CounterRotating Vibrator Drive | Technical Basis: Two synchronized eccentric mass vibrators generating a pure linear motion; lubrication system with temperature monitoring | Operational Benefit: Provides consistent material travel speed and depth control; ensures drive reliability under 24/7 operation | ROI Impact: Predictable performance with mean time between failures (MTBF) exceeding industry average by 25%.

Modular Screen Deck Assemblies | Technical Basis: Boltin deck frames with standardized tensioning systems for various media types (rubber,polyurethane,wedge wire) | Operational Benefit: Enables rapid media changeout (<4 hours per deck) and easy adaptation to different product specifications | ROI Impact: Minimizes production loss during product changeovers and reduces maintenance downtime.

6. APPLICATION SCENARIOS

[Steel Mill Blast Furnace Feed Preparation]

Challenge:: Existing screens experienced rapid blinding with wet coke fines,causing undersized material to carry over into the BF feed,sizing control was lost within weeks of a deck change.
Solution:: Installation of two LCVS3080 units equipped with polyurethane antiblinding panelsand heated decksfor moisture management.
Results:: Achieved consistent ≤5mm fines removal;deck service interval extended from11 weeksto28 weeks;blast furnace gas utilization improved due to stable feedstock sizing.

[Coke Plant Coke Breeze Recovery]

Challenge:: Significant revenue loss from valuable coke breeze (5mm) escaping as uncontrolled dust during primary crushingand screening.
Solution:: Implementationof anenclosed Luxury Coke Vibration Screenwith fine wedge wire panels(2mm x25mm slots)as a secondary dedustingscreen.
