1. PAINPOINT DRIVEN OPENING

Is your coke handling operation losing profitability to screening inefficiency? The cost of poor classification extends far beyond the initial equipment price. Consider these common challenges:
Blinding & Carryover: Moisture and fines adhere to screen decks, blinding apertures and forcing oversized material into your finished product, degrading quality and risking customer rejection.
Excessive Downtime & Maintenance: Frequent deck changes, bearing failures, and structural fatigue from highimpact loading create unpredictable stoppages, disrupting downstream processes.
High Energy Consumption & Noise: Inefficient vibratory mechanisms consume excess power, while poor isolation transmits damaging vibrations to support structures, increasing operational costs and environmental noise levels.
Inconsistent Grade Control: Variable feed rates and composition lead to inconsistent sizing, causing bottlenecks in blast furnaces or sintering plants and impacting overall metallurgical efficiency.

Are you seeking a screening solution that directly addresses these reliability and costperton challenges? The specification of a correctly engineered vibration screen is a critical operational decision.

2. PRODUCT OVERVIEW

The CE Marked Coke Vibration Screen is a heavyduty, linear motion screening machine engineered for the precise size classification of metallurgical coke (5mm 80mm) in charging systems, coke breeze recovery, and presinter screening applications.

Operational Workflow:
1. Controlled Feed: Coke is delivered via conveyor onto the screen's feed box, which distributes material evenly across the full width of the top deck.
2. Efficient Stratification & Separation: HighGforce linear vibration stratifies material rapidly. Fines pass through the upper deck apertures; midsize material is separated on lower decks; oversize travels to the discharge end.
3. Precise Discharge: Correctly sized fractions are discharged into distinct chutes or conveyors for routing to storage bins or downstream processes.

Application Scope: Ideal for blast furnace coke screening (2575mm), nut coke separation (1025mm), and breeze recovery (<10mm) in integrated steel plants and coke production facilities.

Limitations: Not designed for sticky materials without pretreatment, extremely abrasive noncoke materials, or as a replacement for crushers in size reduction circuits.

6. APPLICATION SCENARIOS

[Integrated Steel Plant Blast Furnace Feed] Challenge: A European steelmaker experienced frequent blinding on their existing screens during humid conditions. This caused oversized coke (>80mm) to enter the BF skip system alongside target fraction material (2575mm), leading to irregular burden distribution within the furnace.Solution: Installation of two CE Marked Coke Vibration Screens with heated screen decks ([Optional Feature]) at their BF stockhouse.Results: Screening efficiency stabilized at >96%. Oversize contamination was eliminated (<0.5%), contributing to more consistent furnace permeability. Annual maintenance costs related to screen upkeep decreased by an estimated €65k.
