1. Addressing Critical Screening Challenges in Coke Handling
Is your coke screening operation a source of consistent cost overruns and production bottlenecks? Inefficient particle separation directly impacts blast furnace efficiency, cilësinë e produktit, dhe buxhetet e mirëmbajtjes. Sfidat kryesore përfshijnë:
Blindness & Bllokim: Adhesive coke fines and moisture cause rapid screen mesh blinding, që kërkon mbyllje të shpeshta për pastrim manual. This can result in 1530% downtime on a single line.
Veshja e tepërt & Mirëmbajtja: The abrasive nature of metallurgical coke accelerates wear on screen decks, burimet, dhe mekanizmat e vibratorëve, leading to high parts replacement costs and unpredictable failures.
Shpërndarja e paqëndrueshme e madhësisë: Poor separation allows undersize fines into the blast furnace feed or oversize material into the byproduct stream, disrupting furnace permeability and reducing yield.
Lodhja strukturore & Transmetimi i dridhjeve: High Gforces needed for effective coke screening can damage support structures and transmit harmful vibrations to adjacent equipment.
Are you evaluating screening solutions that offer higher availability, kosto më e ulët, and precise grading to protect downstream processes?
2. Pasqyrë e produktit: HeavyDuty Coke Vibration Screens
A Ekrani i dridhjeve të koksit është një kapacitet i lartë, bruteforce separator designed for the rigorous dry or slightly damp screening of metallurgical coke. Its primary function is to ensure a consistent, specificationgrade feed for blast furnaces while removing undersize coke breeze for other uses.
Rrjedha e punës operative:
1. Prezantimi i ushqimit: Runofoven (ROO) coke is uniformly distributed onto the inlet end of the inclined screen deck.
2. Ndarja vibruese: An eccentric vibrator assembly imparts a linear or elliptical throwing motion, stratifying material and propelling it along the deck.
3. Size Segregation: Particles smaller than the screen aperture fall through as undersize (fllad koks), while larger particles travel across the deck as productsized coke.
4. Shkarkimi: Correctly sized coke discharges at the deck end for furnace charging; undersize material is collected separately.
Fusha e Aplikimit: Madhësia kryesore e koksit metalurgjik (typically 25mm80mm fractions), scalping of oven discharge material, and recovery of coke from slag. Not recommended for wet screening or extremely sticky materials without specialized deck technology.

6.Skenarët e aplikimit
Impianti i integruar i çelikut – Përgatitja e ushqimit të furrës së shpërthimit
Sfida: A major mill experienced frequent blinding on its primary coke screens during humid months. This caused backfeeding onto conveyors and inconsistent size feed (<25mm fines exceeding spec), disrupting blast furnace stability. Manual cleaning was required every two shifts.
Zgjidhje: Installation of a new heavyduty Coke Vibration Screen featuring a polyurethane balltray antiblinding system and variablespeed drives.
Rezultatet: Screen blinding was eliminated entirely between scheduled monthly inspections. The ability to adjust vibration parameters ensured consistent sizing yearround, resulting in a measured <2% oversize/undersize fraction. Furnace permeability improved by an estimated 8%.
Merchant Coke Producer – Byproduct Revenue Optimization
Sfida: The client’s existing screens allowed excessive productsized coke (25mm+) into the breeze stream sold as lowvalue fuel. This represented a significant loss of premium product revenue.
Zgjidhje: Retrofitting their screening station with precision Coke Vibration Screens featuring multideck configurations for tighter cutpoint control.
Rezultatet: A postinstallation audit showed a reduction in misplaced product from ~12% to under 3%. This recovery added approximately $180k annually in recaptured revenue at prevailing market prices.
