1. PAINPOINT DRIVEN OPENING

Is your coke handling operation losing profitability to persistent screening bottlenecks? Common challenges with standard coke vibration screens include:

Excessive Blinding & Carryover: Moisture and fine coke particles adhere to screen decks, blinding apertures and forcing oversized material into finished product bins, compromising quality and risking customer rejection.
Premature Deck & Structural Fatigue: The abrasive nature of metallurgical coke, combined with highimpact loading from feed chutes, leads to frequent screen cloth replacement and unexpected structural weld failures, causing unplanned downtime.
Inefficient Fines Separation: Inadequate vibration dynamics fail to properly stratify material, resulting in valuable coke fines reporting to the oversize stream or insufficient removal of subspec material, directly impacting yield and revenue.
High Maintenance Burden & Downtime: Traditional designs require frequent bearing lubrication, lengthy deck changeouts, and constant tension adjustments. This translates to high labor costs and lost production hours.

Are you seeking a coke vibration screen solution engineered to maximize uptime, protect product grade integrity, and reduce your total cost of ownership?

2. PRODUCT OVERVIEW: HeavyDuty Coke Vibration Screen

This equipment is a highcapacity, linear motion vibrating screen specifically engineered for the sizing and scalping of metallurgical coke in battery charge preparation and coke sorting plants. Its design prioritizes durability, material separation accuracy, and operational continuity in harsh 24/7 environments.

Operational Workflow:
1. Controlled Feed Reception: Coke from crushers or feed conveyors is directed onto the screen’s robust feed box, which evenly distributes material across the full width of the first deck.
2. Efficient Stratification & Separation: A powerful dualvibrator motor system generates a linear throwing motion, aggressively propelling material forward while stratifying it by size for precise passage through deck apertures.
3. Accurate Product Stream Division: Sized fractions are discharged via dedicated spouts—typically producing clean oversize (e.g., +25mm blast furnace coke), intermediate product (e.g., nut coke), and controlled fines (e.g., 10mm breeze).

Application Scope: Primary sizing of hot or cold metallurgical coke, scalpings of oven charge material, dedusting of coke breeze. Not recommended for sticky materials without specialized deck systems or for extremely corrosive chemical environments without specified material upgrades.

3. CORE FEATURES

Modular Deck System | Technical Basis: Tensioned rubberclad panels with polyurethane side tension strips | Operational Benefit: Singlepanel replacement in under 30 minutes vs. full deck changes; reduced downtime by up to 70% for maintenance | ROI Impact: Cuts labor hours per changeout and increases plant availability for production.

AntiBlinding & Wear System | Technical Basis: Integrated ball tray decks or urethanecoated wire mesh with nonstick properties | Operational Benefit: Continuous microimpact dislodges sticky fines; wearresistant surfaces extend deck life 35x over mild steel | ROI Impact: Reduces consumable costs by lowering deck replacement frequency and maintains consistent screening efficiency.

Dual Synchronized Vibrator Drive | Technical Basis: Two externally mounted motors with forced synchronization through a gear coupling system | Operational Benefit: Provides stable linear motion; allows easy adjustment of amplitude; if one motor fails, the unit safely coasts down preventing catastrophic damage | ROI Impact: Eliminates risk of costly twinshaft breakdowns and simplifies drive maintenance.

Ruggedized Frame Construction | Technical Basis: Finite Element Analysis (FEA)optimized side plates with reinforced cross members and hardfaced wear liners at load points | Operational Benefit: Withstands continuous impact from large coke lumps; prevents crack propagation in highstress areas | ROI Impact: Extends structural service life beyond 10+ years under heavy duty cycles, protecting capital investment.

Environmental Sealing & Dust Management | Technical Basis: Multilabyrinth seals on bearing housings combined with easily accessible dust covers at transfer points | Operational Benefit: Excludes abrasive coke dust from critical vibrator bearings; contains airborne particulate at discharge spouts | ROI Impact: Extends bearing service intervals to over 12,000 hours and supports plantwide dust compliance.

6. APPLICATION SCENARIOS

[Steel Plant – Blast Furnace Coke Preparation] Challenge: A major integrated steel mill faced inconsistent blast furnace coke sizing (+25mm fraction). Their existing screens experienced rapid blinding due to moisture variation, allowing oversized (+50mm) lumps into the BF feed conveyor system.

[Coke Sorting Plant – Product Yield Optimization] Challenge: A merchant coke producer needed sharper separation between nut coke (1025mm) and coke breeze (10mm) fractions to meet premium customer specifications. Their legacy screens suffered from poor stratification.

[Solution:] Implementation of a customdesigned twodeck linear motion vibrating screen featuring antiblinding ball tray decks on the top panel for scalpings. The bottom finescreen deck utilized a slotted polyurethane panel for precise fines removal.

[Results:] Oversize contamination in the BF feed fell by over . Product consistency improved significantly. The new design also reduced annual maintenance downtime related to screen changes by an estimated .

[Solution:] Installation of a highprecision threedeck vibrating screen. The unit was configured with a steppeddeck design using specialized urethane screen surfaces optimized for nearsize separation.

[Results:] Screening efficiency for the target fractions increased from . This directly enhanced product value. The robust construction also reduced vibration transmission to the supporting structure.
