1. PAINPOINT DRIVEN OPENING

Is your bulk coke handling operation plagued by persistent bottlenecks and quality control issues? For plant managers overseeing coke screening, common challenges directly impact throughput and profitability. Are you experiencing excessive fines contamination in your product stream, leading to rejected loads and customer penalties? Does frequent screen cloth blinding from sticky coke breeze force unplanned downtime for manual cleaning, halting your entire feed line? Are you replacing worn screen decks or entire vibration screen units far too often due to the abrasive nature of bulk coke, incurring high parts and labor costs? The cumulative effect is measurable: reduced screening efficiency, inconsistent product gradation, and elevated maintenance overhead. The central question becomes: how can you achieve consistent, highvolume separation of bulk coke with greater reliability and a lower total cost of ownership?

2. PRODUCT OVERVIEW

This content details our engineered Bespoke Coke Vibration Screen, a heavyduty linear motion screening machine specifically designed for the rigorous separation of metallurgical and petroleum coke. The operational workflow is built for continuous bulk handling:
1. Controlled Feed: Bulk coke is introduced via an integrated feed box that evenly distributes material across the full width of the screening deck.
2. HighCapacity Stratification: Dual counterrotating exciters generate a forceful linear motion, aggressively conveying and stratifying coke across the durable screen cloth.
3. ​Precise Separation: Sized material separates; oversize particles discharge at the head, while correctly sized product passes through the deck apertures.
4. Efficient Discharge: Separated fractions are discharged via dedicated chutes into designated hoppers or conveyors.

Application scope includes primary sizing of runofoven coke, dedusting (removal of 3mm or 6mm fines), and scalping off oversized material. This equipment is designed for hightonnage fixed plant installations and is not typically suited for mobile applications or for processing materials with extreme moisture content that promotes severe claylike adhesion.

3. CORE FEATURES

HeavyDuty Deck Frame | Technical Basis: Modular, bolttogether design with reinforced cross members | Operational Benefit: Withstands high impact loads from large coke pieces & allows for individual panel replacement | ROI Impact: Reduces deck replacement costs by up to 60% compared to welded frames

AntiBlinding System | Technical Basis: Strategically placed urethane ball trays or flexible slipper pads beneath deck | Operational Benefit: Continuous tapping action dislodges particles stuck in apertures, maintaining open area & screening efficiency | ROI Impact: Sustains rated throughput & minimizes manual cleaning downtime

DustEncapsulated Exciters | Technical Basis: Labyrinth seals & pressurized grease purging system | Operational Benefit: Protects critical bearings from pervasive coke dust ingress, the primary cause of bearing failure | ROI Impact: Extends drive system service life, reducing unplanned failures by an estimated 40%

Adjustable Vibration Parameters | Technical Basis: Variable weight configuration on exciter shafts | Operational Benefit: Allows tuning of amplitude & throw to match specific coke characteristics (density, lump size) for optimal stratification | ROI Impact: Maximizes yield of onspec product & improves overall separation accuracy

AbrasionResistant Lining Package | Technical Basis: Bolton AR steel liners at feed point & side plates | Operational Benefit: Protects structural framework from direct abrasive wear, extending carcass life | ROI Impact: Transforms wear from a structural issue into a simple liner replacement, lowering longterm capital expenditure

6. APPLICATION SCENARIOS

[Steel Mill – Blast Furnace Feed Preparation] Challenge: A major integrated steel mill faced inconsistent blast furnace performance linked to variable coke size distribution (25mm fines exceeding allowable limits), causing irregular permeability and increased fuel rate.

[Solution:] Implementation of a bespoke doubledeck linear motion vibration screen for final coke sizing ahead of furnace bins. The unit was tuned for precise removal of sub25mm material.

[Results:] Achieved consistent furnace feed with fines content maintained below 5%. Plant data indicated a 2% reduction in coke rate and improved gas flow stability.

[Coke Calcining Plant – Product Dedusting] Challenge: A calciner needed to remove ultrafines (3mm) from premiumgrade anode petroleum coke postcrushing but experienced rapid screen blinding with existing technology, requiring hourly stoppages.

[Solution:] Installation of a widebody singledeck bespoke vibration screen equipped with an intensive multiball antiblinding system.

[Results:] Screening efficiency for 3mm removal sustained above 94%. Manual cleaning intervals extended from every hour to once per shift, increasing available production time by over 15%.
