Coke Vibration Screen Fabricators R&D
1. HAPJE NGA PIKA E DIKIMIT
A është rrënuar operacioni juaj i trajtimit të koksit nga pengesat e vazhdueshme dhe kostot e përshkallëzuara të mirëmbajtjes?? Për menaxherët e impianteve dhe kontraktorët inxhinierikë, the screening phase is a critical pressure point. Sfidat e zakonshme përfshijnë:
Verbimi & Transporti: Moisture and fine coke breeze adhere to screen decks, verbimi i hapjeve dhe mbartja e materialit me forcë. This contaminates product grades and necessitates frequent, unproductive stoppages for manual cleaning.
Veshja e tepërt e kuvertës & Kostot e zëvendësimit: The abrasive nature of metallurgical coke accelerates wear on screen panels and support structures. Premature failure leads to high parts replacement costs and significant labor expenditure for changeouts.
Lodhja strukturore & Vibration Isolation Failures: Inadequate dynamic balancing or isolation can transmit destructive forces to the support structure and building. This results in cracked welds, çështjet e themelit, and collateral damage to surrounding equipment.
Kufizimet e xhiros & Përmasat e paqëndrueshme: An undersized or inefficient screen becomes the plant’s bottleneck, limiting overall production capacity. Inconsistent particle separation directly impacts downstream process efficiency and final product quality.
Are you seeking a screening solution that directly addresses these reliability and costperton challenges? Specifikimi i juaj Ekrani i dridhjeve të koksit is not just an equipment purchase—it’s a decisive factor in your plant’s operational uptime and profitability.
2. PËRMBLEDHJE E PRODUKTIT
Ekrani i dridhjeve të koksit HeavyDuty është me kapacitet të lartë, linear motion screening machine engineered for the rigorous separation of hot or cold metallurgical coke. Its design focuses on durability, material stratification, and precise size classification in coke oven byproduct plants, blast furnace feed systems, and anodegrade coke processing.
Rrjedha e punës operative:
1. Feed & Shpërndarja: Coke feedstock is uniformly introduced onto the robust feed box, which distributes material across the full width of the primary screen deck.
2. Stratifikimi & Ndarja: The dual eccentric shaft drive assembly generates a forceful linear throwing motion. Ky veprim shtreson materialin, forcing fines downward through defined screen apertures while conveying oversize along the deck length.
3. Përmasat & Shkarkimi: Konfigurime të shumta të kuvertës (në mënyrë tipike 13 kuvertën) allow for precise multifraction separation (p.sh., koks arrë nga flladi). Correctly sized fractions are discharged via dedicated chutes for downstream processing or stockpiling.
Fusha e Aplikimit: Madhësia kryesore e koksit të furrës së shpërthimit (2575mm), ndarja e koksit të arrave (1025mm), heqja e pluhurit të erës së koksit (10mm), and scalping of hot coke from ovens.
Kufizimet kryesore: Not designed for sticky materials without predrying or specialized deck treatments. Maximum feed temperature typically limited by bearing housing cooling systems and deck material selection.
