Tregtarët e ekranit me dridhje të qëndrueshme të koksit
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 uzinës që mbikëqyrin shqyrtimin e koksit, Sfidat e zakonshme ndikojnë drejtpërdrejt në përfitimin dhe kohën e funksionimit. Excessive fines carryover due to inefficient separation leads to product quality issues and revenue loss. Verbimi i shpeshtë i leckës së ekranit nga ngjitja, moist coke drastically reduces throughput, forcing costly, mbyllje të paplanifikuara për pastrim manual. The intense abrasion of raw coke accelerates wear on critical components, resulting in high parts replacement costs and inventory overhead. Për më tepër, excessive vibration transmission to the support structure creates longterm integrity concerns and unsafe working conditions.
How do you achieve consistent product sizing with minimal fines generation? What solutions exist to drastically reduce screen maintenance intervals and associated labor costs? Can a Ekrani i dridhjeve të koksit be engineered to withstand extreme abrasion while protecting your plant’s infrastructure? The following content addresses these operational challenges with a focus on measurable performance and total cost of ownership.
2. PËRMBLEDHJE E PRODUKTIT
A Ekrani i dridhjeve të koksit is a heavyduty industrial screening machine designed for the highvolume separation and classification of metallurgical coke, koks nafte, dhe koks shkritor. Its primary function is to size coke into precise fractions (p.sh., koks furre shpërthyese, koks arrë) while removing undersize fines and contaminants.
Rrjedha e punës operative është projektuar për detyrë të vazhdueshme:
1. Prezantimi i ushqimit: Bulk coke is uniformly distributed onto the feed end of the inclined screen deck(s).
2. Stratifikimi & Ndarja: Intensiteti i lartë, linear or elliptical vibratory motion stratifies the material bed. Grimcat më të vogla kalojnë përmes hapjeve të panelit të ekranit me madhësi të saktë.
3. Transporti & Shkarkimi: The vibratory action conveys oversize material along the deck length to a designated discharge spout, while sized fractions are discharged separately.
4. Mbajtja e pluhurit: Enclosed designs with integrated dust skirts minimize particulate emission.
Application scope includes primary screening after crushers, final product sizing before shipment, dhe scalping e shkarkimit të furrës. Limitations include handling extremely wet or sticky materials without predrying or specialized deck treatments.

6. Skenarët e APLIKIMIT
Përgatitja e ushqimit për furrën e shpërthimit të fabrikës së çelikut
Challenge A major integrated steel mill faced inconsistent blast furnace coke sizing (2575mm), with high fines (<10mm) carryover exceeding 7%. This led to irregular furnace permeability, increased coke rate consumption (~5kg/THM), and frequent screen cloth changes every 10 javë.
Solution Installation of a doubledeck linear motion Ekrani i dridhjeve të koksit fitted with customaperture polyurethane panels.
Results Fines carryover reduced to under 2%. Panel life extended to over 11 muaj për grup. The improved size consistency contributed to a documented reduction in specific coke rate by approximately ~4kg/THM.
Petroleum Coke Terminal PreShipment Screening
Challenge A bulk terminal needed to ensure strict size specification compliance for multiple clients shipping calcined petroleum coke (<50mm lumps). Their existing screens caused excessive degradation, generating excess fines that reduced saleable product yield.
Solution Implementation of a singledeck elliptical motion Ekrani i dridhjeve të koksit with a gentler discharge trajectory designed for fragile materials.
Results Product degradation during screening was reduced by an estimated ~40%. Saleable product yield increased by over ~3%, directly improving revenue per shipment while meeting all client specifications consistently.
