Fleta e të dhënave të shitësit të ekranit të dridhjeve të koksit
1. HAPJE NGA PIKA E DIKIMIT
A është rrënuar operacioni juaj i trajtimit të koksit nga pengesat e vazhdueshme?, kostot e tepërta të mirëmbajtjes, dhe cilësi të paqëndrueshme të produktit? Për menaxherët e uzinës që mbikëqyrin shqyrtimin e koksit, sfidat e përbashkëta ndikojnë drejtpërdrejt në fund:
Verbimi & Transporti: Moisture and fine particles blind screen decks, reducing effective screening area and forcing material carryover. This contaminates product grades and creates costly rehandling.
Koha e tepruar joproduktive & Mirëmbajtja: Standard vibrators and bearings fail under continuous heavy loads, duke çuar në mbyllje të paplanifikuara. Të dhënat e industrisë tregojnë se disa operacione humbasin 15% of available runtime to screen maintenance.
Lodhja strukturore & Frame Cracking: The abrasive nature of coke and highcycle vibration induce metal fatigue in inadequately designed frames, resulting in catastrophic failures and expensive structural repairs.
Ndarja joefikase e gjobave: Modelet e paqëndrueshme të dridhjeve nuk arrijnë të ndajnë siç duhet flladin nga koksi i arrave, leaving potential revenue unrealized and causing downstream process issues.
Are you searching for a screening solution engineered to withstand the specific demands of coke classification with higher availability and lower total cost of ownership?
2. PËRMBLEDHJE E PRODUKTIT: Ekrani i dridhjeve të koksit HeavyDuty
The HeavyDuty Coke Vibration Screen is a bruteforce linear motion screening machine engineered for the primary sizing, skalping, and dedusting of metallurgical and petroleum coke. Its design prioritizes structural integrity and material stratification to handle hightonnage, abrasive applications.
Rrjedha e punës operative:
1. Furnizimi i kontrolluar: Coke is directed onto the robust feed box, which distributes material evenly across the full width of the primary screen deck.
2. HighEnergy Stratification: A dualshaft, synchronized vibrator assembly generates a linear throwing motion. This action aggressively stratifies the material bed, forcing fines downward for rapid separation.
3. Përmasat e sakta: Sized fractions pass through defined deck apertures (zakonisht rrjetë teli ose panele poliuretani). Oversize material travels over the deck surface to a designated discharge spout.
4. Protected Discharge: Sized fractions are discharged through sealed discharge spouts designed to minimize dust emission and spillage.
Fusha e Aplikimit & Kufizimet:
Fushëveprimi: Ideal for primary screening of hot or cold coke (koks arrë, fllad) in coke plants, mullinj çeliku, and anode production facilities. Capable of handling feed sizes typically from 080mm.
Kufizimet: Not designed as a replacement for finewet screening or dewatering applications. Maximum efficiency is achieved with controlled feed rates as per designed capacity.
