1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Votre opération de manutention de coke est-elle en proie à une qualité de produit incohérente, génération d'amendes excessives, and unplanned maintenance halts? Pour les directeurs d'usine supervisant le criblage du coke, common challenges directly impact profitability and throughput:
Contamination du produit & Rejections: Inefficient separation allows undersize fines to contaminate blast furnace feedstock or anodegrade product, leading to customer penalties and degraded metallurgical performance.
Premature Screen Deck Failure: The extreme abrasiveness of hot or cold coke accelerates wear on screen panels and support structures, provoquant de fréquents, costly replacements and production stoppages.
Aveuglant & Reporter: Sticky coke particles and moisture can blind screen apertures, while insufficient vibration leads to material carryover, drastically reducing effective screening capacity and classification accuracy.
Fatigue structurelle & Transmission des vibrations: Poorly engineered vibratory motion transmits damaging harmonics to the base frame and surrounding infrastructure, risking longterm structural integrity.

Are you seeking a screening solution engineered not just to move material, but to precisely classify it while withstanding the punishing environment of coke handling? The right bespoke vibration screen is a capital investment in predictable grading and operational continuity.

2. APERÇU DU PRODUIT

A Bespoke Coke Vibration Screen is a heavyduty industrial screening machine specifically designed for the sizing, scalper, or dedusting of metallurgical coke (cold or hot) et coke de pétrole. Engineered from the ground up for this application, it replaces generic screens that fail under abrasive loads.

Flux de travail opérationnel:
1. Alimentation contrôlée: Coke is introduced via a regulated feed chute onto the screen’s inlet section, distributing load across the full deck width.
2. Stratification à haute intensité: A precisely tuned vibratory mechanism (typically dual eccentric shaft or bruteforce design) imparts a linear or elliptical motion, aggressively stratifying material. Fines are forced downward to contact the deck.
3. Séparation précise: Stratified particles pass through accurately sized screen panel apertures (grillage, polyuréthane, ou plaque perforée), separating into defined size fractions (par ex., +50mm, 50mm+25mm, 25mm).
4. Décharge efficace: Sized fractions discharge via dedicated chutes into separate collection conveyors or bins for downstream processing.

Champ d'application: Criblage primaire et secondaire du coke métallurgique (blast furnace foundry), coke de pétrole anodisé, calcined coke. Suitable for sinter feed preparation and coke breeze recovery.
Limites: Not designed for wet screening processes or as a replacement for crushers. Maximum feed temperature and particle size are defined by specific material specifications.
