1. ABERTURA ACIONADA POR PAINPOINT

Sua operação de manuseio de coque é prejudicada pela qualidade inconsistente do produto?, geração excessiva de multas, e paradas de manutenção não planejadas? Para gerentes de fábrica que supervisionam a triagem de coque, common challenges directly impact profitability and throughput. Você está experimentando:

Cegagem & Transferir: Moisture or sticky fines blinding screen decks, causing product contamination and forcing premature shutdowns for manual cleaning.
Tempo de inatividade excessivo: Frequent bearing failures or structural fatigue on vibrating screens leading to 2040 hours of unscheduled downtime annually for repairs and parts replacement.
Altos custos de manutenção: The abrasive nature of coke accelerating wear on screen panels, convés, e excitadores, resulting in high consumable costs and labor for changeouts.
Inefficient Sizing: Inconsistent feed rates or improper vibration dynamics producing offspec material, leading to customer rejections or reprocessing costs.

A questão central é: como você pode conseguir resultados precisos, reliable coke classification while maximizing equipment uptime and minimizing total cost of ownership? The answer lies in selecting a purposeengineered Peneira vibratória de coque.

2. VISÃO GERAL DO PRODUTO

UM Peneira vibratória de coque is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions—typically nut coke, brisa, and lump coke—after the quenching process. Its robust construction handles highly abrasive materials while resisting corrosion from residual moisture.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Quenched coke is conveyed onto the screen’s feed box, distributing material evenly across the full width of the top deck.
2. Separação de alta intensidade: A dualvibrator mechanism imparts a linear or elliptical motion, stratifying material and propelling particles across the screen cloths.
3. Dimensionamento preciso: Oversize material travels across the top deck apertures, while correctly sized particles pass through to lower decks for further fractionation.
4. Descarga & Transporte: Separated fractions discharge via dedicated chutes onto designated conveyors for stockpiling or direct feed to blast furnaces.

Escopo de aplicação & Limitações:
Escopo: Ideal for sinter plants, sistemas de carregamento de alto-forno, and foundry operations requiring strict size control (por exemplo, 2540mm nut coke). Effective for hot or cold coke screening postquenching.
Limitações: Não projetado para processos de peneiramento úmido ou como substituto para telas de escalpelamento que manuseiam telas extremamente grandes (+300milímetros) feedstock without prior crushing. Performance is contingent on proper installation on a structurally adequate support base.
