1. ABERTURA ACIONADA POR PAINPOINT

Is your coke handling operation losing profitability to persistent screening bottlenecks? Common challenges with standard coke vibration screens include:

Excessive Blinding & Transferir: A umidade e partículas finas de coque aderem às plataformas de peneiramento, blinding apertures and forcing oversized material into finished product bins, compromising quality and risking customer rejection.
Premature Deck & Fadiga Estrutural: The abrasive nature of metallurgical coke, combined with highimpact loading from feed chutes, leads to frequent screen cloth replacement and unexpected structural weld failures, causando tempo de inatividade não planejado.
Separação ineficiente de multas: Inadequate vibration dynamics fail to properly stratify material, resulting in valuable coke fines reporting to the oversize stream or insufficient removal of subspec material, directly impacting yield and revenue.
Alta carga de manutenção & Tempo de inatividade: Traditional designs require frequent bearing lubrication, lengthy deck changeouts, and constant tension adjustments. This translates to high labor costs and lost production hours.

Are you seeking a coke vibration screen solution engineered to maximize uptime, protect product grade integrity, and reduce your total cost of ownership?

2. VISÃO GERAL DO PRODUTO: Peneira vibratória de coque resistente

Este equipamento é de alta capacidade, linear motion vibrating screen specifically engineered for the sizing and scalping of metallurgical coke in battery charge preparation and coke sorting plants. Seu design prioriza durabilidade, material separation accuracy, and operational continuity in harsh 24/7 ambientes.

Fluxo de Trabalho Operacional:
1. Controlled Feed Reception: Coke from crushers or feed conveyors is directed onto the screen’s robust feed box, que distribui uniformemente o material por toda a largura do primeiro deck.
2. Estratificação Eficiente & Separação: A powerful dualvibrator motor system generates a linear throwing motion, aggressively propelling material forward while stratifying it by size for precise passage through deck apertures.
3. Accurate Product Stream Division: Sized fractions are discharged via dedicated spouts—typically producing clean oversize (por exemplo, +25mm blast furnace coke), intermediate product (por exemplo, coque de nozes), and controlled fines (por exemplo, 10mm breeze).

Escopo de aplicação: Primary sizing of hot or cold metallurgical coke, scalpings of oven charge material, dedusting of coke breeze. Not recommended for sticky materials without specialized deck systems or for extremely corrosive chemical environments without specified material upgrades.

3. RECURSOS PRINCIPAIS

6. CENÁRIOS DE APLICAÇÃO

[Steel Plant – Blast Furnace Coke Preparation] Desafio: A major integrated steel mill faced inconsistent blast furnace coke sizing (+25fração de mm). Their existing screens experienced rapid blinding due to moisture variation, allowing oversized (+50milímetros) lumps into the BF feed conveyor system.

[Coke Sorting Plant – Product Yield Optimization] Desafio: A merchant coke producer needed sharper separation between nut coke (1025milímetros) and coke breeze (10milímetros) fractions to meet premium customer specifications. Their legacy screens suffered from poor stratification.

[Solução:] Implementation of a customdesigned twodeck linear motion vibrating screen featuring antiblinding ball tray decks on the top panel for scalpings. The bottom finescreen deck utilized a slotted polyurethane panel for precise fines removal.

[Resultados:] Oversize contamination in the BF feed fell by over . Product consistency improved significantly. The new design also reduced annual maintenance downtime related to screen changes by an estimated .

[Solução:] Installation of a highprecision threedeck vibrating screen. The unit was configured with a steppeddeck design using specialized urethane screen surfaces optimized for nearsize separation.

[Resultados:] Screening efficiency for the target fractions increased from . This directly enhanced product value. The robust construction also reduced vibration transmission to the supporting structure.
