1. ABERTURA ACIONADA POR PAINPOINT

A sua operação de triagem de coque é afetada por, ineficiências dispendiosas? Para gerentes de fábrica e empreiteiros de engenharia, the challenges of screening metallurgical coke directly impact throughput, qualidade do produto, e lucratividade final. Os pontos problemáticos comuns incluem:

Geração excessiva de multas: Aggressive or poorly tuned vibration can degrade premium coke into undersized fines, reducing valuable product yield and creating excess waste material.
Cegagem & Transferir: Sticky coke breeze and moisture cause screen mesh blinding, while insufficient vibration leads to material carryover. Both scenarios force frequent stoppages for manual cleaning and result in inconsistent size fractions.
Alto tempo de inatividade para manutenção: Constant, heavyduty operation leads to premature failure of screen decks, molas, and vibrator motors. Unplanned downtime for repairs disrupts blast furnace feed schedules.
Inefficient Capacity Management: A singlescreen setup cannot adapt to varying feed rates or different size specifications, creating bottlenecks in highvolume operations.

Are you facing rising operational costs due to screen maintenance and product loss? Is your current equipment failing to deliver consistent grade separation under full load? The solution requires a purposeengineered approach to material handling.

2. VISÃO GERAL DO PRODUTO

The Coke Vibration Screen is a heavyduty industrial screening machine designed for the precise separation of metallurgical coke into defined size fractions (por exemplo, coque de alto forno, coque de nozes). It operates on the principle of applied vibration to stratify and convey material across a screening surface.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Sized coke from the crusher is evenly distributed onto the inlet end of the vibrating screen deck via a feed box or conveyor.
2. Estratificação & Separação: Alta frequência, lowamplitude vibration fluidizes the bed of material. Smaller particles sift through the apertures of the screen cloth (painel), while oversized particles travel across the deck surface.
3. Descarga Eficiente: Correctly sized material (throughs) discharges from a lower outlet chute. Material superdimensionado (overs) travels along the deck length and discharges from the end, directed to downstream processes.

Escopo de aplicação: Primary and secondary sizing of metallurgical coke in coke plants, siderúrgicas, and ferroalloy facilities. Adequado para triagem de coque quente ou frio.

Limitações: Not designed for wet screening or slurries without significant modification. Maximum lump size is constrained by feed chute and deck design specifications.
