1. PAINPOINT DRIVEN OPENING

Is your coke screening operation plagued by persistent inefficiencies that erode profitability? Common challenges include:

Blinding & Carryover: Moisture and fine particles blind screen decks, reducing effective screening area and forcing material carryover. This leads to inconsistent product grading and potential downstream process contamination.
Excessive Downtime & Maintenance: Frequent breakdowns from highimpact loads and abrasive coke require constant screen cloth changes and structural repairs, costing hundreds of production hours annually.
High Energy Consumption: Inefficient vibration mechanisms and overengineered drives consume excessive power without proportional gains in throughput or separation accuracy.
Poor Scalability: Fixedfrequency screens cannot adapt to variations in feed rate or material characteristics, creating bottlenecks in highcapacity sorting lines.

Are you seeking a robust screening solution that directly addresses these issues with proven engineering, reduces your total cost of ownership, and delivers consistent, specgrade coke?

2. PRODUCT OVERVIEW

Our heavyduty Coke Vibration Screen is engineered for the precise dry or wet screening of metallurgical coke, petroleum coke, and similar abrasive carbon materials. It is a linear motion vibrating screen designed for highcapacity sizing and scalping operations in coke ovens, steel plants, and carbon anode production facilities.

Operational Workflow:
1. Controlled Feed: Coke is fed onto the feed box for even distribution across the full width of the upper deck.
2. Efficient Stratification: The dualvibrator generated linear motion rapidly stratifies material, forcing fines downward through the screen media while conveying oversize toward the discharge end.
3. Precise Separation: Multiple deck configurations allow for simultaneous separation into several precise size fractions (e.g., blast furnace coke, nut coke, breeze).
4. Clean Discharge: Sized fractions are discharged into separate chutes with minimal intermixing for downstream processing or stockpiling.

Application Scope & Limitations:
Scope: Ideal for sizing (25mm to 3mm), scalping (+80mm), dedusting, and dewatering of coke. Suitable for both stationary plants and largescale bulk handling terminals.
Limitations: Not designed for sticky materials without specialized screen media or wash systems. Maximum lump size is constrained by feed chute and deck design specifications.

6. APPLICATION SCENARIOS

Steel Plant Blast Furnace Feed Preparation | Challenge: Existing screens blinded frequently due to seasonal moisture in coke supply, causing undersize "breeze" (<10mm) to contaminate BF charge bins at rates exceeding acceptable limits (~12%). This compromised furnace permeability and efficiency.| Solution: Installation of two parallel widebody Coke Vibration Screens equipped with polyurethane flipflow panels on the bottom deck specifically for the critical <10mm separation.| Results: Screening efficiency for 95%. Breeze carryover reduced below target threshold of <5%. Panel changeout intervals extended from every month quarterly.
