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, qualité du produit, et budgets d'entretien. Les principaux défis comprennent:
Blindness & Colmatage: Adhesive coke fines and moisture cause rapid screen mesh blinding, nécessitant des arrêts fréquents pour un nettoyage manuel. This can result in 1530% downtime on a single line.
Usure excessive & Entretien: The abrasive nature of metallurgical coke accelerates wear on screen decks, ressorts, et mécanismes vibrateurs, leading to high parts replacement costs and unpredictable failures.
Inconsistent Size Distribution: Poor separation allows undersize fines into the blast furnace feed or oversize material into the byproduct stream, disrupting furnace permeability and reducing yield.
Fatigue structurelle & Transmission des vibrations: 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, coût inférieur, and precise grading to protect downstream processes?

2. Présentation du produit: HeavyDuty Coke Vibration Screens

UN Écran vibrant de coke est une grande capacité, 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.

Flux de travail opérationnel:
1. Présentation du flux: Runofoven (ROO) coke is uniformly distributed onto the inlet end of the inclined screen deck.
2. Séparation vibratoire: An eccentric vibrator assembly imparts a linear or elliptical throwing motion, stratifying material and propelling it along the deck.
3. Ségrégation par taille: Particles smaller than the screen aperture fall through as undersize (brise de coca), while larger particles travel across the deck as productsized coke.
4. Décharge: Correctly sized coke discharges at the deck end for furnace charging; undersize material is collected separately.

Champ d'application: Primary sizing of metallurgical coke (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.
