1. ABERTURA ACIONADA POR PAINPOINT

Is your coke processing operation struggling with inefficient screening that directly impacts product quality and plant profitability? Common challenges with outdated or undersized vibration screens include:

Contaminação excessiva de finos: Inconsistent particle separation allows undersized coke fines into the product stream, degrading metallurgical grade quality and triggering price penalties from buyers.
Entupimento frequente da tela & Tempo de inatividade: Moisture or sticky material leads to rapid blinding of screen decks, exigindo frequência, costly production stops for manual cleaning.
Alta manutenção & Custos de substituição: Constant vibration and abrasive coke particles cause premature failure of screen panels, convés, e excitadores, leading to high spare part inventories and labor costs.
Insufficient Capacity for Peak Loads: A screen that cannot handle surge feed from crushers or upstream processes becomes a bottleneck, limitando o rendimento geral da planta.

Are you asking how to achieve sharper size cuts, reduce unplanned stoppages, and extend the operational life of your screening equipment? The solution lies in selecting a purposeengineered Coke Vibration Screen Processing Plant.

2. VISÃO GERAL DO PRODUTO

A Coke Vibration Screen Processing Plant is a centralized screening system designed for the highvolume, abrasive classification of metallurgical coke. It typically integrates heavyduty vibrating screens with feed and discharge chutes, gabinetes de poeira, and support structures to form a complete processing module.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Crushed coke is conveyed onto the screen via an adjustablerate feeder, ensuring even distribution across the full width of the screening surface.
2. MultiDeck Separation: The material travels over vibrating screen decks equipped with abrasionresistant wire mesh or polyurethane panels. Defined topdeck apertures remove oversize material for recirculation, while bottomdeck apertures separate onspec product from fines.
3. Stream Segregation: Correctly sized product discharges via the main outlet. Oversize and undersize fractions are directed into separate collection chutes for return to crushers or disposal.

Escopo de aplicação & Limitações:
This system is engineered for dry screening of metallurgical coke (alimentação de sinterização, coque de alto forno) and similar carbon materials. Optimal performance requires controlled feed moisture; highly wet or sticky materials may require predrying or alternative screening technologies such as roller screens.
