1. PAINPOINT DRIVEN OPENING

Is your coke handling operation plagued by persistent bottlenecks and escalating maintenance costs? For plant managers and engineering contractors, inefficient screening directly impacts the bottom line. Are you facing these common challenges?

Excessive Downtime: Frequent screen cloth blinding and premature wear from abrasive coke fines lead to unplanned shutdowns, halting the entire processing line.
Poor Product Quality: Inconsistent particle size separation results in offspec coke, leading to customer rejections, reprocessing costs, and revenue loss.
High Operational Costs: Constant manual cleaning, frequent component replacement, and high energy consumption from inefficient vibratory mechanisms drain your maintenance budget.
Structural Integrity Concerns: Excessive vibration transfer to support structures creates longterm fatigue risks, demanding costly structural reinforcements.

The core question is: how can you achieve reliable, consistent coke classification while controlling total cost of ownership? The answer lies in selecting a Coke Vibration Screen engineered specifically for these harsh operational realities.

2. PRODUCT OVERVIEW

A Coke Vibration Screen is a heavyduty industrial screening machine designed for the precise size separation of metallurgical or petroleum coke after crushing. Its primary function is to ensure a consistent product grade by removing fines and oversize material.

Operational Workflow:
1. Feed Introduction: Crushed coke is uniformly fed onto the inclined screen deck(s) via a feed box or chute.
2. Vibratory Separation: Highintensity, linear or circular vibratory motion stratifies the material. Smaller particles pass through the screen apertures (undersize), while larger particles travel across the deck surface (oversize).
3. Product Discharge: Separated fractions are discharged via distinct outlets—undersize (coke breeze/fines) and oversize (finished product)—for downstream handling or storage.

Application Scope & Limitations:
Scope: Ideal for dry screening of metallurgical and petroleum coke in sizing applications (e.g., separating +25mm, 25mm+10mm, 10mm fractions). Suitable for both stationary plants and largescale bulk handling terminals.
Limitations: Not designed for wet screening processes or for materials with extreme moisture content that causes severe sticking. Maximum feed size is typically limited to 200250mm, depending on model.

3. CORE FEATURES

Modular Deck System | Technical Basis: Independently tensioned polyurethane or wire mesh panels | Operational Benefit: Panels can be replaced individually in under 30 minutes without dismantling the frame, drastically reducing downtime for cloth changes. | ROI Impact: Cuts screen cloth replacement labor time by up to 70% versus bolteddown systems.

AntiBlinding Deck Technology | Technical Basis: Integrated rubber ball trays or ultrasonic deblinding systems beneath the screen cloth | Operational Benefit: Continuous microimpact dislodges particles trapped in apertures, maintaining nearoriginal screening efficiency throughout the shift. | ROI Impact: Sustained throughput prevents capacity drops of 1530%, eliminating costly production shortfalls.

HuckBolted Frame Construction | Technical Basis: Highstrength steel side plates joined with aerospacegrade Huck fasteners instead of traditional welding | Operational Benefit: Eliminates stress fractures and weld fatigue failures at highstress points; provides superior structural integrity under continuous heavy load. | ROI Impact: Field data shows a reduction in catastrophic frame failures by over 90%, avoiding weeks of unplanned downtime.

Adjustable Vibration Parameters | Technical Basis: Variable frequency drive (VFD) control on vibrator motors or adjustable eccentric weights | Operational Benefit: Operators can finetune amplitude and frequency to match specific coke characteristics (density, moisture) for optimal separation efficiency. | ROI Impact: Maximizes yield of onspec product by improving separation accuracy by an estimated 515%.

Base Isolation Spring System | Technical Basis: Multistage composite rubber springs or coil springs with damping elements | Operational Benefit: Isolates up to 95% of dynamic forces from the supporting structure, minimizing vibration transmission and preventing structural damage. | ROI Impact: Removes the need for expensive reinforced foundations, reducing civil work costs by approximately 25%.
