High Quality Coke Vibration Screen Dealer
1. PAINPOINT DRIVEN OPENING
Is your coke screening operation plagued by persistent inefficiencies that erode profitability? For plant managers and engineering contractors, the challenges of screening highquality metallurgical or foundry coke are multifaceted. Are you experiencing excessive fines generation due to aggressive screening action, directly reducing your yield of premium product? Does frequent screen cloth blinding from sticky coke breeze lead to constant downtime for manual cleaning, halting your entire processing line? Are you battling with premature wear on screen decks and components from highly abrasive materials, resulting in unpredictable maintenance costs and parts replacement cycles? Furthermore, does the inherent dust generation during screening create environmental control issues and product loss? These operational hurdles translate into quantifiable costs: reduced throughput, higher labor for maintenance, increased spare parts inventory, and suboptimal product grading that affects sales revenue. The central question is: how can you achieve precise, efficient, and reliable coke classification while maximizing the yield of your highvalue product fraction?
2. PRODUCT OVERVIEW
This content details a specialized HighQuality Coke Vibration Screen, an industrialgrade screening machine engineered for the dry separation of metallurgical and foundry coke into precise size fractions. Its design prioritizes gentle yet effective material handling to preserve coke integrity.
The operational workflow is straightforward:
1. Feed Introduction: Sized coke from crushers or feed stockpiles is evenly distributed onto the screen's inlet.
2. Stratified Separation: A controlled vibratory motion stratifies the material bed, allowing undersize particles (coke breeze) to pass through the specified screen cloth apertures.
3. Product Discharge: Correctly sized oversize material (lump coke) discharges at the head end, while undersize material collects beneath the deck for separate conveyance.
4. Continuous Operation: The system operates continuously under heavy load, with parameters adjustable to match specific feed characteristics.
Application scope includes primary sizing of oven discharge coke, secondary screening for blast furnace fractions (e.g., 2580mm), and recovery of breeze from runofoven material. This equipment is not designed for wet screening or for processing extremely hot materials directly from ovens without appropriate cooling.

6. APPLICATION SCENARIOS
[Metallurgical Coke Plant Blast Furnace Feed] Challenge: A major steel producer needed consistent supply of +25mm lump coke but faced high fines content (10mm) exceeding furnace specifications after primary crushing and screening.
[Solution HighQuality Coke Vibration Screen Implementation]: A tripledeck unit replaced an older screener, configured with precisely tuned amplitude to minimize drop height between decks.
[Results Quantifiable Outcomes]: Fines generation in the target +25mm fraction was reduced by 18%. Annual yield of saleable blast furnace coke increased by approximately $450K USD value.
[Foundry Coke Producer Product Grading] Challenge: A producer required three distinct grades (e.g., large foundry lumps, small cupola nuts, breeze) but existing screens caused excessive breakage of fragile highcarbon coke.
[Solution HighQuality Coke Vibration Screen Implementation]: Installation of a doubledeck unit featuring lowstress vibration technology and polyurethane screens on the top deck.
[Results Quantifiable Outcomes]: Product degradation was minimized, improving the yield of premium large foundry lumps by over $200K annually per line.
