1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your coke handling operation struggling with persistent bottlenecks and escalating costs? Pour les directeurs d'usine supervisant le criblage du coke, common challenges directly impact profitability and uptime. Excessive fines generation due to aggressive screening action can degrade product value. Frequent screen cloth blinding from moist or sticky material leads to constant manual cleaning, halting the line. Unplanned downtime for deck replacements or structural repairs creates costly production gaps. High vibration transmission to the support structure accelerates wear on surrounding infrastructure, increasing maintenance overhead. Êtes-vous confronté à une augmentation des coûts opérationnels, classement des produits incohérent, and unreliable throughput in your classification process? The efficiency of your downstream processes depends on the performance of your primary screening equipment.

2. APERÇU DU PRODUIT

The Custom Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise dry separation of metallurgical coke and petroleum coke. Its design focuses on durability and consistent performance in harsh, abrasive environments typical of coke handling plants.

Flux de travail opérationnel:
1. Présentation du flux: Bulk coke is fed uniformly onto the feed box of the Custom Coke Vibration Screen.
2. Stratification & Séparation: A highGforce linear or elliptical motion stratifies material rapidly; sized particles pass through precisely tensioned screen decks.
3. Décharge du produit: Correctly sized coke (par ex., coke de haut fourneau, coca aux noix) is discharged via designated chutes, while oversize material is separately conveyed for potential crushing.

Champ d'application: Primary sizing of hot or cold coke, dépoussiérage (removal of breeze), scalping of oversized material ahead of crushers.
Limites: Non conçu pour le criblage humide ou les applications de boues. Optimal performance requires controlled feed rates and specific moisture content parameters to prevent blinding.
