1. ABERTURA ACIONADA POR PAINPOINT

Sua operação de manuseio de coque é atormentada por gargalos persistentes e custos crescentes de manutenção?? Para gerentes de fábrica que supervisionam a triagem de coque, desafios comuns impactam diretamente os resultados financeiros. Excessive fines carryover due to inefficient separation can degrade product quality and reduce saleable yield. Frequent screen cloth changes, caused by premature wear from abrasive coke, lead to hours of unplanned downtime and high consumables expenditure. Vibration isolation failures transfer destructive forces to support structures, criando preocupações de integridade de ativos de longo prazo. Além disso, inconsistent feed rates and moisture content can overwhelm standard screens, causing blinding and a significant drop in throughput. Você está enfrentando custos operacionais crescentes, disponibilidade imprevisível, and an inability to meet stringent sizing specifications consistently? The reliability of your entire downstream process hinges on the performance of this critical node.

2. VISÃO GERAL DO PRODUTO

The Coke Vibration Screen is a heavyduty, linear motion screening machine engineered for the precise size classification of metallurgical coke and similar abrasive materials in bulk handling plants. Its core function is to separate crushed coke into defined fractions (por exemplo, coque de alto forno, coque de nozes) ao remover multas.

Fluxo de Trabalho Operacional:
1. Alimentar & Distribuição: Crushed coke is evenly distributed across the full width of the screen via a robust feed box.
2. Estratificação & Separação: Dual counterrotating exciters generate a linear vibrating motion, stratifying material and conveying it along the deck while precise sizing occurs through the screen meshes.
3. Descarga de Fração: Correctly sized oversize material discharges from the front of the deck; onsize material passes through to lower decks or chutes; fines are separated and discharged separately.

Escopo de aplicação: Triagem primária e secundária de coque metalúrgico, recrusher feed screening, separação da brisa de coque.
Limitações: Não projetado para pegajoso, highly cohesive materials without specialized deck systems. O tamanho máximo do pedaço é limitado pelo design da calha de alimentação e da abertura do convés.
