Zbritje e shpërndarësve të ekranit të dridhjeve të koksit
1. HAPJE NGA PIKA E DIKIMIT
Is your coke handling operation plagued by persistent inefficiency and hidden costs? Për menaxherët e impianteve dhe kontraktorët inxhinierikë, the screening phase is a critical bottleneck with direct consequences for profitability. Sfidat e zakonshme përfshijnë:
Gjenerimi i gjobave të tepërta: Inefficient screening leads to overbreaking of coke, converting valuable product into lowvalue fines. This represents a direct loss of revenue per ton.
Bllokim i shpeshtë i ekranit & Koha e ndërprerjes: Sticky coke particles and moisture cause blinding, që kërkon mbyllje të shpeshta për pastrim manual. Kjo kohë joproduktive e paplanifikuar ndalon të gjithë linjën tuaj të përpunimit.
Klasifikimi i paqëndrueshëm i produktit: An unreliable screen fails to deliver precise size separation, compromising the quality specifications demanded by your blast furnace or foundry customers, risking contract compliance.
Mirëmbajtje e lartë & Kostot e zëvendësimit: Vibrating screens that are not engineered for the abrasive nature of coke suffer rapid wear on decks, burimet, dhe ngacmuesit, duke çuar në konsum të lartë të pjesëve të këmbimit dhe kosto të punës.
Are you ready to reduce your costperton, rritja e disponueshmërisë së impiantit, and ensure a consistently onspec product? The solution lies in specifying a purposebuilt Ekrani i dridhjeve të koksit.
2. PËRMBLEDHJE E PRODUKTIT
A Ekrani i dridhjeve të koksit is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions after crushing. Its core function is to ensure only correctly sized coke proceeds to blast furnace charging or shipment.
Rrjedha e punës operative:
1. Prezantimi i ushqimit: Crushed coke is uniformly fed onto the inclined screen deck(s) via a feed box or chute.
2. Ndarja vibruese: Intensiteti i lartë, linear or circular vibration stratifies the material. Smaller particles pass through the screen media apertures (nënpërmasa), ndërsa grimcat më të mëdha udhëtojnë nëpër sipërfaqen e kuvertës (tepër i madh).
3. Devijimi i produktit: Separated fractions are discharged via distinct chutes—typically into oversize (return for recrush), madhësia e produktit, and fines hoppers.
Fusha e Aplikimit: Primary sizing of metallurgical coke in coke plants, mullinj çeliku, dhe terminalet e trajtimit me shumicë. Suitable for hot or cold coke screening.
Kufizimet kryesore: Not designed for wet screening processes or for materials with extreme adhesive properties without specialized deck treatments.
