1. ABERTURA ACIONADA POR PAINPOINT

Is your coke handling and screening operation a constant source of bottlenecks, dores de cabeça de manutenção, and product quality inconsistencies? Para gerentes de fábrica e empreiteiros de engenharia, the challenges of screening coke are distinct and costly.

Tempo de inatividade excessivo para alterações no deck de tela: Frequent blinding and wear on traditional screens force lengthy, laborintensive media replacements, interrompendo toda a sua linha de processamento.
Geração Não Controlada de Multas & Degradação do Produto: Aggressive vibration or improper screen action can break down coke lumps, creating excess fines that devalue your product and reduce yield.
Altos custos de manutenção & Fadiga dos Componentes: A natureza abrasiva do coque acelera o desgaste nas peneiras, molas, e mecanismos vibratórios, leading to unpredictable repair cycles and spare parts inventory costs.
Separação Ineficiente & Missed Contaminants: Inconsistent material travel or insufficient screening intensity can allow oversized contaminants or undersized fractions to pass, compromising blast furnace feed quality.

Are you evaluating equipment that can extend service intervals, proteger a integridade do produto, and deliver a measurable return on investment through sustained throughput? The engineering behind your Peneira vibratória de coque is critical to solving these operational challenges.

2. VISÃO GERAL DO PRODUTO

A peneira vibratória de coque para serviço pesado é uma peneira vibratória de alta capacidade, linear motion screening machine engineered for the precise sizing and scalping of metallurgical coke in bulk material handling systems. Its design prioritizes durability and consistent performance in harsh, ambientes abrasivos.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Coke from a crusher or feed conveyor is evenly distributed across the full width of the screen’s inlet.
2. Estratificação Linear & Dimensionamento: Motores vibradores duplos em contra-rotação geram um movimento de lançamento linear. Esta ação estratifica o leito de material, allowing finer particles to contact the screen media while conveying larger lumps toward the discharge end.
3. Separação precisa: Sized fractions pass through defined screen deck apertures (typically wire mesh or polyurethane panels) into separate discharge chutes.
4. Descarga Eficiente: Coca de tamanho correto (por exemplo, coque de alto forno) is discharged as product, while oversize material (por exemplo, +80milímetros) or undersize fines (por exemplo, 25milímetros) are diverted for recirculation or disposal.

Escopo de aplicação: Primary sizing/scalping of metallurgical coke postcrushing; separação da brisa de coque; dedusting applications.
Limitações: Not designed for sticky or moist materials without pretreatment; maximum feed size is limited by inlet design and deck robustness.

6. CENÁRIOS DE APLICAÇÃO

Usina Siderúrgica Integrada – Preparação de Alimentação de Alto Forno

Desafio: A major steel producer experienced excessive blast furnace fines due to aggressive screening action breaking down coke lumps at their sinter plant feed line. This led to reduced permeability in the BF and higher fuel rates.
Solução: Implementation of a customengineered Coke Vibration Screen with controlled linear stroke technology specifically tuned for lump integrity preservation.
Resultados: Incidental fines (10milímetros) generation was reduced by 18%. This improved BF operational stability and delivered an estimated annual fuel cost saving based on improved burden permeability.

Coke Production Facility – Product Classification

Desafio: Postcrushing screening operations were plagued by rapid screen cloth blinding from sticky residual volatiles, requiring weekly shutdowns for cleaning and replacement—costing over 300 horas de produção perdida anualmente.
