1. PAINPOINT DRIVEN OPENING

Is your petroleum coke screening operation plagued by persistent, costly inefficiencies? For plant managers and engineering contractors, the challenges of processing bulk coke are familiar: excessive dust generation creating environmental and health hazards, blinding of screen decks leading to catastrophic drops in throughput, and severe abrasion from coke’s sharp edges causing premature wear and unplanned downtime. Each hour of lost screening capacity directly impacts your bottom line through delayed shipments and increased labor for manual clearing. Are you constantly balancing the tradeoff between screening accuracy and machine longevity? What is the true cost of your current screen’s vibration profile on both product quality and structural integrity? The right certified Coke Vibration Screen is not just a purchase; it’s a strategic investment in predictable, profitable operation.

2. PRODUCT OVERVIEW

A Certified Coke Vibration Screen is a heavyduty, highcapacity linear or elliptical motion vibrating screen specifically engineered for the dry separation of calcined or green petroleum coke (petcoke). Its design prioritizes durability, dust containment, and consistent sizing under continuous, abrasive loads.

Operational Workflow:
1. Feed Introduction: Bulk coke is conveyed onto the robust feed box, which evenly distributes material across the full width of the primary screen deck.
2. Stratification & Separation: The precisely tuned vibratory motion stratifies material, forcing fines through the specified aperture sizes while moving oversize particles toward the discharge end.
3. Sized Product Handling: Correctly sized coke fractions discharge into segregated chutes or conveyors for stockpiling or loading, while oversize material may be crushed and recirculated or stockpiled separately.

Application Scope & Limitations:
This equipment is designed for hightonnage sizing (e.g., 3/8" x 6 mesh, 4 mesh x 10 mesh) of petroleum coke in bulk terminal and calcining plant applications. It is not suitable for wet screening processes or for materials with high moisture content that would promote pastelike blinding. Maximum efficiency is achieved with properly precrushed feed material.

3. CORE FEATURES

Sealed DustContainment System | Technical Basis: Full perimeter rubber dust seals combined with negative pressure zones at transfer points | Operational Benefit: Reduces airborne particulate emissions by over 95%, ensuring compliance with site environmental standards and improving operator health & safety conditions | ROI Impact: Mitigates risk of regulatory fines, reduces housekeeping labor, and minimizes product loss as dust.

AntiBlinding Deck Technology | Technical Basis: Polyurethane or rubber screen panels with slotted apertures combined with optional ball tray or ultrasonic deblinding systems | Operational Benefit: Maintains consistent open screen area by preventing nearsize particles from lodging in apertures, ensuring stable throughput rates over extended shifts | ROI Impact: Eliminates costly production pauses for manual cleaning; improves overall screening efficiency by 1525%.

AbrasionResistant Liner Package | Technical Basis: Wear liners fabricated from AR400 steel or equivalent at all impact points (feed box, side plates) | Operational Benefit: Protects the structural frame from direct coke abrasion, extending the service life of critical components by 35x compared to mild steel | ROI Impact: Drastically reduces maintenance part replacement costs and extends major overhaul intervals.

Balanced DualVibrator Drive | Technical Basis: Two synchronized vibratory motors generating a linear or elliptical motion with adjustable amplitude via outofbalance weights | Operational Benefit: Provides consistent material travel speed and stratification without transmitting destructive harmonic vibrations to the support structure | ROI Impact: Lowers structural support costs, reduces bearing stress for higher uptime (typically >98%), and cuts energy consumption per ton screened.

Modular Deck Assembly | Technical Basis: Independently tensioned screen decks using a clamp rail system without weldedin cross members | Operational Benefit: Allows for rapid panel changeout (3050% faster) and enables easy adaptation to different product size specifications by swapping panel types | ROI Impact: Reduces downtime for screen changes from hours to minutes, increasing operational flexibility.

6. APPLICATION SCENARIOS

Bulk Terminal Loading Facility | Challenge: A major export terminal faced severe dust emissions during final screening before ship loading, risking environmental noncompliance. Frequent screen blinding also created bottlenecks, delaying vessel turnaround times.| Solution: Implementation of a largecapacity Certified Coke Vibration Screen featuring a fully enclosed design with integral dust skirts and antiblinding polyurethane panels.| Results: Airborne dust at the shiploader was reduced to within permitted levels without additional baghouse capacity. Screening throughput stabilized, contributing to an average vessel loading time reduction of 8%.

Calciner Plant Product Sizing Circuit | Challenge: Anodegrade calcined coke required precise sizing (4mm +10mesh). The existing screens suffered rapid wear on wire cloth decks, causing size distribution drift and requiring weekly changeouts that halted production.| Solution: Installation of two parallel Coke Vibration Screens equipped with specialized abrasionresistant rubber screen panels featuring slotted apertures.| Results: Panel life extended to over three months per set. Product consistency improved significantly (±2% variance on target fraction), enhancing product premium. Annual maintenance labor hours dedicated to screen upkeep fell by over 60%.
