1. PAINPOINT DRIVEN OPENING

Is your coke handling operation plagued by persistent bottlenecks, excessive fines generation, and unplanned maintenance? Inefficient screening directly impacts your bottom line through lost product, increased energy consumption for downstream processes, and costly downtime for screen deck replacements. Are you currently facing:

High Fines Carryover: Ineffective separation leading to valuable coke breeze contaminating finished product or overloading crushers, reducing overall yield and saleable tonnage.
Premature Deck Failure: Abrasive coke particles rapidly degrading standard screen panels, resulting in frequent, disruptive shutdowns for maintenance and high consumable costs.
Blinding & Plugging: Moisture or sticky fines clogging screen apertures, drastically reducing effective screening area and throughput capacity.
Excessive Vibration Transmission: Poorly isolated equipment sending damaging vibrations to support structures, creating safety concerns and necessitating costly structural reinforcement.

The right Coke Vibration Screen is not just a piece of equipment; it’s a critical process gatekeeper. How do you select a unit that maximizes uptime, protects product integrity, and delivers a measurable return on investment?

2. PRODUCT OVERVIEW

The HeavyDuty Coke Vibration Screen is a highcapacity, brute force screening machine engineered for the primary sizing and scalping of metallurgical coke. It separates crushed coke into precise fractions (e.g., blast furnace coke, nut coke, breeze) while efficiently removing fines.

Operational Workflow:
1. Feed Introduction: Crushed coke is uniformly fed onto the inclined screen deck via a feed box or chute.
2. Stratification & Separation: Highintensity, linear or elliptical vibration stratifies material. Oversize particles travel rapidly across the deck surface while undersize material passes through the rugged panel apertures.
3. Fraction Discharge: Separated material streams are discharged via distinct outlets into designated chutes or conveyors for further processing or stockpiling.

Application Scope:
Primary sizing/scalping of metallurgical coke postcrusher.
Removal of coke breeze (010mm) from blast furnace feed stock.
Sizing of nut coke and other specific fractions.

Limitations:
Not designed for fine screening below 3mm; alternative technologies like probability screens are recommended.
Requires controlled feed rate and uniformity for optimal performance; surge loads can reduce efficiency.

3. CORE FEATURES

Modular Deck System | Technical Basis: Boltin, interchangeable panel design with multiple wear materials | Operational Benefit: Enables rapid changeout of worn sections (<4 hours vs. full deck replacement). Reduces downtime by over 70% for maintenance events. | ROI Impact: Cuts labor costs and inventory holding costs for spare decks.

HighStrength Side Plates with Internal Reinforcements | Technical Basis: Finite Element Analysis (FEA)optimized steel plates with integrated ribbing | Operational Benefit: Withstands extreme dynamic loads from heavy coke lumps without fatigue cracking or deformation. | ROI Impact: Eliminates unscheduled downtime from structural failure and extends machine service life by years.

DualMass Vibrator System | Technical Basis: Two counterrotating shafts generating a linear force while minimizing power consumption | Operational Benefit: Delivers consistent, highGforce vibration for efficient stratification without transmitting destructive forces to the support structure. Your building frame is protected. | ROI Impact: Reduces energy use by up to 30% compared to bruteforce singlemass designs and removes need for costly structural upgrades.

AbrasionResistant Panel Options | Technical Basis: Panels available in AR400 steel, rubberclad steel, or polyurethane with varied aperture designs (square, slot) | Operational Benefit: Matches wear material to your specific coke abrasiveness and moisture profile to triple panel service life versus standard options. | ROI Impact: Directly lowers consumable costs per ton screened by optimizing the costtowearlife ratio.

Centralized Greasing & Condition Monitoring Points | Technical Basis: Lube lines routed to all major bearing points with accessible vibration sensor ports | Operational Benefit: Enables proactive lubrication and realtime bearing health monitoring during operation, preventing catastrophic bearing failure. | ROI Impact: Transforms maintenance from reactive to predictive, avoiding a single major bearing failure event that can cost over $50k in parts and lost production.

6. APPLICATION SCENARIOS

[Integrated Steel Mill – Blast Furnace Feed Prep] Challenge: A major mill experienced excessive fines (<10mm) in their BF charge due to an aging screen with severe blinding issues (~22% fines carryover), increasing fuel rate and reducing furnace efficiency.Solution: Installation of a primary Coke Vibration Screen featuring nonblinding polyurethane slot panels on the bottom deck.Results: Fines carryover reduced to <8%. Achieved payback in under 11 months through reduced coke rate and increased furnace productivity.

[Coke Production Plant – Product Classification] Challenge: A producer needed sharper separation between nut coke (1025mm) and blast furnace coke (>25mm) but faced rapid wear on traditional wire mesh panels requiring monthly changes.Solution: Implementation of a twodeck heavyduty unit with topdeck AR400 panels for scalp removal and bottomdeck rubberclad perforated panels for precise final sizing.Results: Panel life extended to over nine months per set while achieving a clean product split with less than 5% contamination between fractions.
