Coke Vibration Screen Vendors Catalog
1. HAPJE NGA PIKA E DIKIMIT
A po lufton operacioni juaj i trajtimit të koksit me pengesa të vazhdueshme?, gjenerimi i gjobave të tepërta, dhe kostot e paplanifikuara të mirëmbajtjes? Inefficient screening directly impacts your plant’s bottom line through lost product, rritja e konsumit të energjisë për proceset në rrjedhën e poshtme, dhe kohë joproduktive të kushtueshme për zëvendësimet e kuvertës së ekranit. Are you currently facing these challenges?
Verbimi & Transporti: Moisture and sticky fines blind screen meshes, reducing effective screening area and forcing material to carry over unscreened, contaminating your product fractions.
Veshja e tepërt & Mirëmbajtja: The abrasive nature of hot coke rapidly degrades standard screen panels and deck components, leading to frequent shutdowns for replacements and high spare parts inventories.
Ndarja joefikase: Inconsistent vibration or inadequate screening area results in poor size distribution control, sending offspec material to crushers or battery bunkers, disrupting the entire production chain.
Lodhja strukturore: The intense impact loads from coke discharge can cause premature failure of the screen body and support structures, risking major operational failure.
The right coke vibration screen is not just a separator; it’s a critical asset for throughput stability and product quality control.
2. PËRMBLEDHJE E PRODUKTIT
The heavyduty coke vibration screen is a highcapacity, linear motion screening machine engineered for the primary sizing and scalping of metallurgical coke. It is designed to withstand extreme abrasion, ndikimi, and thermal stress in coke handling plants.
Rrjedha e punës operative:
1. Feed & Shpërndarja: Hot or cooled coke from a conveyor is discharged onto a robust feed box or plate, distributing the material evenly across the full width of the first screen deck.
2. Primary Stratification & Përmasat: The powerful dualvibrator motor drive generates a linear throwing motion. Ky veprim shtreson shtratin material, forcing fines downward through the apertures of the upper deck(s) while conveying oversize toward the discharge end.
3. Fraction Separation: Multiple deck levels (në mënyrë tipike 2 ose 3) with precisely sized screen media (rails, tela të endur, ose panele poliuretani) separate the coke into defined product streams (p.sh., koks furre shpërthyese, koks arrë, fllad).
4. Shkarkimi: Sized fractions are discharged via separate chutes for transport to storage bunkers or downstream processes.
Fusha e Aplikimit & Kufizimet:
Fushëveprimi: Ideal for primary screening of metallurgical coke after quenching or crushing; scalping of ovenrun coke; separation of coke breeze from larger fractions in byproduct recovery.
Kufizimet: Not designed as a dewatering screen for slurries. Maximum feed temperature is determined by specific component selection (p.sh., heatresistant seals, motor isolators). Materialet tepër ngjitëse mund të kërkojnë para-trajtim ose sisteme të specializuara pastrimi të kuvertës.

6. Skenarët e APLIKIMIT
Impianti i integruar i çelikut – Përgatitja e ushqimit të furrës së shpërthimit
Sfida: A major steel producer experienced rapid blinding of woven wire screens during humid conditions at their BF coke bunker station. This caused significant nut coke fraction carryover into blast furnace feed bins (~12%), disrupting burden permeability and increasing fuel rate.
Zgjidhje: Implementation of two largecapacity linear motion screens fitted with nonblinding rod deck media on the upper decks for scalping oversize and openprofile polyurethane panels on lower decks for precise nut/breeze separation.
Rezultatet: Screening efficiency stabilized above 96%. Carryover was reduced to <3%. The plant reported an annual reduction in fuel rate attributed partly to improved burden control alongside a 65% drop in monthly screenrelated downtime.
Coke Plant – ByProduct Recovery Circuit
Sfida: A standalone coking plant needed to maximize recovery of saleable “nut” coke from its crushing circuit but struggled with excessive generation of undersize “breeze” due to aggressive screening action degrading fragile pieces.
Zgjidhje:: Installation of a threedeck unit featuring adjustable stroke length via external counterweights on its vibrator motors was selected. This allowed operators finetune intensity based on feed characteristics..
Rezultatet: By optimizing stroke,,the plant increased yield within target nut size range (+8%) while reducing undersize generation (15%). The gentler handling also extended lowerdeck panel life by approximately 30%.
