1. ABERTURA ACIONADA POR PAINPOINT

Is your coke screening operation a source of constant cost and disruption? Para gerentes de fábrica e empreiteiros de engenharia, os desafios da triagem de coque metalúrgico a granel impactam diretamente o rendimento, qualidade do produto, e orçamentos de manutenção. Os pontos problemáticos comuns incluem:
Tempo de inatividade excessivo: Frequent screen cloth changes due to rapid blinding and abrasion from sharp, hard coke particles halt your entire processing line.
Geração Não Controlada de Multas: Inefficient screening creates excessive 5mm fines, degrading product value and creating handling issues for blast furnace operations.
Altos custos de manutenção: The punishing environment leads to premature failure of screen decks, molas, e rolamentos, driving up spare parts inventories and labor hours.
Classificação inconsistente do produto: Separação inadequada resulta em material fora das especificações, leading to customer rejections or penalties tied to size distribution guarantees.
Ineficiência Energética: Poorly designed vibratory systems consume excess power without delivering proportional screening performance.

Are you seeking a robust solution that reduces total cost of ownership while ensuring consistent grade control? The right industrial coke vibration screen is engineered to address these exact operational challenges.

2. VISÃO GERAL DO PRODUTO

A heavyduty coke vibration screen is a highcapacity, linear motion screening machine designed for the scalping and precise size classification of hot or cold metallurgical coke. Its primary function is to separate crushed or processed coke into defined fractions (por exemplo, +25mm coque de alto forno, 1025mm coque de nozes, 10mm brisa) with high efficiency and reliability.

Fluxo de Trabalho Operacional:
1. Alimentar & Distribuição: Bulk coke is fed onto the robust feed box, que distribui uniformemente o material por toda a largura da plataforma de peneira primária.
2. Separação de tamanho: The dual eccentric shaft vibrator assembly drives the screen box on a linear path. Coke travels over sequentially finer screen cloths (typically wire mesh or polyurethane panels), with undersize material falling through each deck.
3. Descarga & Coleção: Correctly sized fractions are discharged from separate discharge spouts into designated chutes or conveyors for stockpiling or further processing.

Escopo de aplicação & Limitações:
Escopo: Ideal para plantas de sinterização, sistemas de carregamento de alto-forno, and coke handling terminals. Suitable for hot coke screening (with heatresistant components) up to ~200°C and cold screening applications.
Limitações: Não projetado para materiais pegajosos sem pré-tratamento. Maximum feed size is constrained by deck aperture and machine design; typically handles feed up to 150200mm.

Solution Installation of a customdesigned twodeck linear motion coke vibration screen with precisely tuned polyurethane panels on the bottom deck for fines removal.
Results Achieved consistent product grading with less than 3% fines in the nut coke fraction. This contributed directly measured improvements in sinter plant yield.

Merchant Coke Producer – Blast Furnace Coke Line

Challenge Excessive downtime for screen maintenance was bottlenecking their final product line before shipment, causing delivery delays.
Solution Replacement of two older screens with new heavyduty units featuring modular deck systems and centralized lubrication points accessible from walkways.
