Coke Vibration Screen Manufacturing Design Service
1. HAPJE NGA PIKA E DIKIMIT
Is your coke handling operation plagued by persistent bottlenecks and escalating maintenance costs? Për menaxherët e impianteve dhe kontraktorët inxhinierikë, shqyrtimi joefikas ndikon drejtpërdrejt në fund. Sfidat e zakonshme përfshijnë:
Verbimi & Transporti: Mirë, sticky coke particles blind screen decks, reducing effective screening area and forcing material carryover into the wrong product streams. This contaminates product grades and necessitates costly reprocessing.
Koha e tepruar joproduktive & Mirëmbajtja: Traditional screens with complex drive mechanisms and numerous moving parts require frequent lubrication, belt changes, and bearing replacements, duke çuar në mbyllje të paplanifikuara.
Konsumi i lartë i energjisë: Inefficient vibratory systems operate at constant high power, regardless of feed conditions, wasting significant energy over thousands of operational hours.
Structural Fatigue & Dështimi: The intense, reciprocating forces from conventional exciters transmit high stress to the screen body and support structure, leading to weld cracks, side plate failures, and shortened equipment lifespan.
Are you seeking a coke vibration screen solution engineered to minimize these operational burdens while maximizing throughput and product consistency?
2. PËRMBLEDHJE E PRODUKTIT
Our engineered service provides heavyduty Coke Vibration Screens, specifically designed for the abrasive and demanding environment of coke handling in steel production, impiante anode, and calcining operations.
Rrjedha e punës operative:
1. Feed & Shpërndarja: Sized coke from crushers or ovens is fed onto the screen’s robust feed box for even distribution across the full width of the screening deck.
2. HighEfficiency Stratification: A powerful, linear vibratory motion stratifies the material bed, forcing fines downward through the screen media while conveying oversize toward the discharge end.
3. Ndarja e saktë: Multiple deck configurations allow for precise separation into two or three distinct product streams (p.sh., nut coke from breeze).
4. Shkarkimi i kontrolluar: Separated fractions are discharged via dedicated chutes for downstream processing or stockpiling.
Fusha e Aplikimit: Primary and secondary screening of metallurgical (u takua) koks, koks nafte (petcoke), and calcined coke in sizing ranges typically from 080mm.
Kufizimet: Not designed for extremely fine classification (<1mm) which requires specialized fine screening technology, or for materials at temperatures exceeding 250°C without specific design adaptations.
